Hi Guys,

Please i need help with my 2010 corolla S P0500 (Vehicle Speed sensor) issue.

Since i got the vehicle August last year, everything has been functioning well except for the ABS, VSC OFF (blinking) & skid control lights on the dashboard. My mechanic diagnosed the vehicle and told me the ABS Pump Assembly was bad and needed replacement... (the code was C1246 - Malfunction in master cylinder pressure sensor). All these didn't affect the vehicle performance except that it would skid when i push hard on the brakes.

Recently I've replaced the ABS Pump Assembly but i now have a P0500 code and my car only shifts between gear 1 and 3. I sometimes have very low RPM when I'm idling too.

Please i need some advice on what to do cuz I've tried the following...
1) I've put back my previous ABS Pump Assembly and it's still the same (now with the abs lights on and check light on too - P0500 & C1246 codes). N/B the new ABS Pump Assembly has the same numbers on them (44540-02110 89541-12450. 133800-4290 QK.)

2) I've replaced the gearbox speed sensor (shown in the picture attached). And it still didn't solve the problem.

3). I've had an auto electrician trace the wires from the gearbox sensor all the way to where it enters the brainbox and he has confirmed there's continuity.

4) All the wheel speed sensors are okay and they are reading correctly (As shown on Live data on a diagnosis machine - Picture attached).

5) I've replaced my vehicle ECU (as directed by my mechanic - he suggested they might have interchanged polarities when they tried jumpstarting the vehicle after i parked it for a long time) and it still didn't solve the problem.

Please i need your inputs cuz I've spent money trying lots of ideas and the latest of them all is that my mechanic asked me to get a new gearbox.

My RPM get's high up to 3600 @ 100km/hr and even up to 4500 @ 120km/hr... Very abnormal

Please if you've experienced this kinda problem, share how you got out of it.

N/B: My odometer wasn't engineered, there's actually 103k now - display ink issue i guess.

Thanks in advance.

OP, these are my final words on this thread, you asked for advice but have consistently ignored well meaning advice.

I will only reopen communication when I see (please see picture below).

Now for the benefit of anyone else who has a 2010 Corolla with P0500:

This is what you need to know.

First, take note that repairs will require access to factory information.

Second, the factory diagnostic information is different depending on the engine installed in your Corolla.

Third, it is not sufficient to search for hits in the open internet, the information therein is incomplete at best and irrelevant/outdated at worst.

Fourth, P0500 is a generic code and implementation varies from manufacturer to manufacturer, and consequently testing and fault isolation procedures can never be the same.

Fifth, due to copyright concerns and indeed respect for copyright, I can only provide highlights....

These are the highlights:

41 documents were responsive to the search.

4 of which are super relevant, the rest address the issue of looking at symptoms not individually but as part of a system, repairing cars today requires that the automotive technician deploy systems thinking and not symptoms thinking.

The information was last modified/updated on: 4-17-2018, that was just 3 months ago for a 2010 car! Those of us with PDFs gotten off the internet would most definitely miss the update!, the update is not even in PDF format but HTTP.

There are 3 other related codes.

The factory manual lists 4 areas to check to resolve this issue and the transmission is not one of them!



From Day 1, I have always made the point that if you bring your repair to me, I will do it exactly the same way as the manufacturer would or a dealer would, I would play by the book, I cannot imagine any other way to fix a car aright.

And that is why my brand specific threads are aptly titled Dealer-Level Diagnostics.

By the way, I am cheaper than the average dealer but costlier than the average shade tree mechanic, but I stand behind my work!

May I respectfully bow out of here.

cc: Uboma

Car manufacturers are also into the business of creating, updating, revising and selling information.

Gone are the days when a single PDF document had all the information one needed to fix a car.

Nowadays, lots of separate PDF documents containing hyperlinks forming a maze of cross-referenced documents form what may be termed the factory service manual for a modern vehicle.

The documentation is so extensive that the vehicle manufacturers have had to resort to technologies such as the below ( see attached picture)

So if you are hunting for factory service manuals online...you are certainly missing out on a lot of information and a lot of interactivity.

Single PDF documents have limitations, but when hyperlinked and interconnected and with the help of the technology highlighted by the technology in the picture below....there are no more limitations!

Points to Ponder! Why would a car manufacturer employ/deploy Big Data to deliver service information?

If your automotive technician is not computer literate and internet savvy, you are on a long thing!

Hi please I would like some professional help, I was advised to change my Nissan Morano Engine and, I did to a new one. Before I changed the engine it was developing fault and, the car was not raising (can't accelerate) the Mechanic checked and said Gear was fine, the engine is bad any way so we changed the engine so we know no major issues than electrical. So we changed the Engine.

Now the car still doesn't raise,
When we put it on it burnt two coils on the new follow come engine.
I have been through hell how come the Electrician mentioned Brain box, but we suspect the wiring is wrong as well.

But given the fact that the car never raised before we changed the engine/(the same electrician said the problem was the engine) and, still isn't raising and the electrician scanned the car nothing less than 3 times and even had to use computer to reset the car and in all this time him and his team of Electricians didn't mention any thing like brain box I want to get rid of him sharply.......

Narailanders we need professional Nissan Morano 2004 USA spec Electrical Bosses and, We need your advice.

(Subject Electrical faults, brain box, burnt coil, new Engine on Nissan Moran 04)

Thank you and God bless Us all...

You never answered me....I just hope those working for you are consulting factory documentation, otherwise, I wonder how they would resurrect a vehicle so greatly abused.

I fixed the drain.

It is now 0.04 amps 5 minutes after shut down

GeorgeIV:
My Murano stops moving when on motion, it also stops when I put on my A/C. My rewire doesn't seem to know what to do, all he keeps telling me is that it's one faulty sensor.
A friend recommended another rewire that used his "machine" to test it, confirmed it was one sensor...worked on it for 32k but it still stops.

Please help out, I've had the car for 4 years and it's been fine until it started stopping lately.

Year?
Location?

Ehybrid:
Good job! I like how you pay attention to detail and specifics as you troubleshoot.
Hope OP was happy with your work.

Will put up pictures later.

Almost done.

I need to redo the wiring of the aftermarket radio connections.

That is what I am doing now.

I took time out to work on a similar vehicle a 2003 Lexus ES330. The problem vehicle in question is a 2004 Lexus ES330 (the one with pictures).

The above stated points are distinctly personal, not professional, the part in bold, specifically.

If his response to a good natured recommendation from you was, in your opinion, uncouth or downright rude, the professional path would be either to state your position, in terms devoid of any bias, or simply to ignore the apparent provocation, like you mentioned you were trained to.

But seizing on an issue on a completely unrelated thread to take subliminal jabs at a contemporary really is not professional. It is personal.

You do not need to respond, as you have stated you do not intend to.

Perhaps the better path, considering the acrimony with that specific contemporary, would be to make your points and proffer your solutions, devoid of any references to him, positive or negative.

That would be the professional thing to do.

Noted with thanks.

I shouldn't have quoted that post.

He gave a restraining order and I wanted to be guided by it.

I should have made my point without quoting the post.

I had no intentions whatsoever of denigrating him.

Thanks for bringing this to my attention.

That was why I deleted his name so I do not appear to be contravening his restraining order...and since it is possible to quote and modify...I did but publicly acknowledged that the original author had not been been quoted word for word.

Any other meanings ascribed to the above was not intended.

Cosplay:
Yes, I did come across that thread as well.

Your professional grouse concerns his, in your opinion, apparently hasty and/or premature transmission change solution to the fault mentioned in that thread?

Did you see when I made a recommendation?

Did you see when I said the likelihood of the issue being remedied free of charge is low?

Did you see the professional response to my recommendation?

Was the remedy provided free of charge in the end?

If no, what was the aim of that retort?

Given the expressly stated feelings of the OP, did the expenses incurred result in a resolution of his crises?

The thread speaks for itself.

Apparently I did wrong to recognize him by recommending him.

I consulted Toyota documentation and technician only repair resources and found the solution to guys problem.

So I will be guided by his expressly stated intentions.

I have nothing more to say on the issue.

Cosplay:
Mr AutoElectNG

I have come across multiple threads laced with efforts by you at, in your words, 'shameless self-promotion'.

While there indeed is nothing untoward with tooting one's own horn, doing so while denigrating or casting aspersions on others' efforts, overtly or subliminally, is rather ungentlemanly.

In addition, the proof of pudding is often in the eating. Perhaps you should let your work speak for itself.

Further, whatever personal grouses you may hold with any members should stay that way: personal.

If, on the other hand, you have a professional bone to pick, you should do the responsible thing and state your issues clearly.

Thank you.

Nothing personal.

The professional issue is clearly stated here https://www.nairaland.com/4568471/please-2010-corolla-p0500-issue.

I was trained to be civil no matter the level of provocation. I have tried to keep things that way.

Uboma,

I have no grouses.

https://www.nairaland.com/4568471/please-2010-corolla-p0500-issue.

Fellow in question left specific instructions in the above thread.

I am currently working on this vehicle as we speak!

I have zeroed in on the problem, an incorrectly installed aftermarket radio and a shoddy headlight assembly and indicator repair

Currently trying to resolve the mess that was created here.

It resulted in a current draw of over 100 milliamps when the car is turned off!

With the headlight assembly and indicator wiring fixed, it reduced to 35 milliamps.

With the aftermarket radio disconnected, it reduced to less than 10 milliamps.

uboma:
Car batteries do not just go bad. The battery I am presently using is 4 years old and counting.

The Alternator may be faulty.

If you in Lagos, contact Gazz.uzz.


Contact ....... if you are in Abuja close by

With all due respect, I have had to make edits to your quote.

I just wanted to make the point that in some climes people are used to batteries lasting as long as 10 years, as well as shameless self-promotion.

And by the way, I can solve any case of battery discharging overnight. I just solved one. A Lexus ES330 with a drain of 100ma that drains overnight. Vehicle bought brand new tokunbo. Seller told buyer that the battery is bad, so buyer sent funds to buy a new battery. Owner bought another battery after it drained the first time. The second time it happened, buyer knew it was not a battery issue. The drain has now been reduced to 10ma after painstaking detective work. But I went a step further...I detected and fixed a number of shoddy electrical repair work involving the airbag circuits (airbags would not deploy in the event of an accident) as well as wrong connections that would cause the dashboard lights to go off if the headlamps were turned on.

When customer service is a priority, your mistakes don't have to cost the client a kobo

amba2017:
what house what could be the. cause and possible solution to missing Battery and key symbol on 2017 landcruiser prado . and the car not starting. have been spending on mechanics since yesterday to bo avail

Was this ever resolved?

Collision repair without connecting airbag sensors to vehicle frame and air bag light blinking on the dashboard is that a proper repair?

Collision repair in Nigeria is monkey business.

Got pictures to back up my claim.

I think we need to introduce collision repair classes to our curriculum and let the public know what signs to look out for when buying vehicles that have been involved in accidents.

Specimen vehicle is a Lexusus ES330 that kills batteries overnight.

Research indicates the vehicle has been involved in two frontal impact accidents.

Repair is more than just cosmetics, repair also has to be electrical and computerized.

I saw a very nice flow chart that explains the difference in the mindset of a mechanic and automotive technician( a cross between mechanic and electrician)

Hook up battery tester. If fail, replace battery. That is if he even has a battery tester

Car starts? Done.

Battery test passes? Battery could still be bad, so replace battery.

Car starts? Done.

Car doesn't start? Send it to the good auto electric guy to test out the alternator and diagnose other problems (and on to the next oil change).

Seriously?

America pays attention to skills in much the way as Nigerians have chosen to pay attention to paper certifications.

SkillsUSA held its 54th annual National Leadership And Skills Conference from June 26.

The competition held on June 27 and 28.

The program would be closing today.

A total of 102 practical skills would be tested in the competition including automotive related skills.

More details here https://www.skillsusa.org/events-training/national-leadership-and-skills-conference/

According to Tomorrow's Technician:

"The SkillsUSA Championships is the nation’s largest workforce development event for middle-school, high-school and college/postsecondary students enrolled in public career and technical education programs."

Will Nigeria/Nigerians ever realize the importance of skills (automotive or otherwise) in today's world?

ayogabriel:
When gazzuz ignores a post twice, does that mean he doesn't have a solution or he is researching

My thoughts on your question:

He has to run his business (make a profit)...receives 150 calls a day(some asking for free not paid advice)...he has a family...he has to spread his time across all those...and all the requests for help on Nairaland...there is so much or so little one can do in 24 hours

radautoworks:
They don't check that in Texas. At annual inspection maybe but it's really about emissions here.

Emissions is what drove OBD II in the first place

I once wrote:

What is OBD II?

The second iteration of the OBD standard, i.e., An enhanced iteration of the OBD standard (capability-wise and standardization-wise)

Before OBD II, different manufacturer had different connectors, different pinouts, different electrical signaling protocols, and different messaging formats, non-standard DTCs.

In other words, you had purchase a different scan tool for every make of vehicle - imagine the cost implications for technicians and their shops in the days prior to OBD II

OBD II is an enhanced diagnostic monitoring tool that is integrated into vehicle PCM or ECU

OBD II allows your PCM or ECU to provide real-time data on its operations

Your PCM or ECU can generate a standardized series of diagnostic trouble codes (DTCs) which helps tremendously in the detection and remediation of faults in the vehicle

OBD II started life around 1994.

OBD II became mandatory in 1996 for all cars meant for the American market

It is basically an emissions standard and was initially designed for the reporting of vehicle emission status, but manufacturers latched onto the standard making it the de facto diagnosis and reprogramming protocol

If your vehicle's emission levels are greater than 1.5 times the originally certified emissions level, it with output a diagnostic trouble code (DTC).

The OBD standard was driven largely by the California Air Resources Board (CARB)'s mission of improving the quality of the environment - hence the statement that it was basically an emissions standard.

OBD II was built from the ground up sense failures in vehicle emissions control systems that would result in increased emission (read that to mean) pollution levels.

These failures could be electrical, chemical or mechanical.

With OBD II, if all systems (electrical, mechanical) except the catalytic converter are functioning perfectly, then there is a problem. A chemical failure. What chemical failure? A catalytic converter failure who is not doing its work.



https://www.youtube.com/watch?v=DXchXMVteyk

And what is the work of a catalytic converter? To chemically purify the air that passes through it! This failure is enough to cause the PCM/ECU to output a code.

This was not the case with OBD I, a chemical failure would not lead to a MIL!

The take-home lesson - OBD I brought drivability to the fore. OBD II brings emission (pollution) levels to the fore.

OBD II will however also output codes related to drivability - but that is not the primary reason why it is monitoring vehicle systems!

What this means is that irrespective of what you think or your friends and neighbors think, if your car was built to this standard, you are driving a modern car! smiley

Brother and Sister, if your technician does not understand this language, you are in big trouble.

If your vehicle is a post 1996 vehicle. If your technician says don’t worry about the MIL, you are in even bigger trouble, because the car is telling you I got an issue, I need a checkup and you are ignoring it.

If your MIL was deleted, by your or the person who sold the car to you, then you know who your enemy is, how you intend to deal with him, well, I’ll leave that to you!


Got questions on OBD II? We will try to answer them in a down-to-earth manner so that anyone can understand!

It was love @ first sight when I saw rx330 in a home movie some years ago (2008 to be precise) it was driven by Emeka Ike in the movie. There and there I said I must own it some day.
Thank God this year I bought mine (ibos say whenever a man wakes up is his morning).
My problem now is that the car runs battery down.
Av bought new battery but case is still same.
If I Park d car by 7pm b4 7am in d morning, d battery wld run down.
I bought another one (a diamond battery) but case is still same.
Pls what do I do. Am scared of 'kassims' in Warri to start tearing my new baby up.
Pls I need advice and like which workshop do I take her to. Even if its ph or Benin am ready to take her there, that's if there r no good car electros in Warri.

Was this ever resolved?

Pitokwe:
May this never be our portion o.

Please car experts,what could lead to car catching fire?
Please educate us so that we can know preventive measures.

A stitch in time.....

1. Electrical Faults poorly repaired can cause a fire, these would include poor insulation of wiring harnesses that were exposed during repair and short circuits

2. Faults affecting the fuel system improperly repaired leading to leaking fuel spraying on hot surfaces and starting a fire

3. Driver negligence...failure to monitor cockpit signals especially the coolant temperature resulting in an engine compartment fire

The maybe others, these readily come to mind

That's our rodent brothers not kazeem

There has got to be a solution to this.....don't you think?

How can highly intelligent beings be at the mercy of lesser intelligent creatures?

You write okay but not as the write in the Quora link in my opinion.

Oh dear...got work to do to become like Wole Soyinka!

magnumwhales:
@autoNG Bro not bragging I no how to use more than 15machines for diagnosis and programming :Techstream for Toyota,ford Ids,HDS for honda, HDMI for BMW and Cooper, Abrite,VAG for VW Star for benz, X100 and T code for key programmin , Tango and Xprog,JLR for Land rover and Jaguar, launch diagun master and many autel product Xtunner and the rest. I was well thought by my former boss I only lost my library to hard disk crash I worked with different cars on electronics and electrical if I will do any training it will be on mechanical which on not ready for now.

Nice resume...all the best in your business...have you raised the remaining balance of the dollars you were looking for to purchase equipment?

And just to make your star shine ever brighter, please refer to the list of 9 essential skills for today's automotive technician as established by the Government of Canada and other national and international agencies, make sure to improve in each one of them...because there is more to being a modern automotive technician than the use of factory diagnostic tools.

You don't have to attend the training I am organizing to benefit from studying and improving the 9 skills listed here https://www.nairaland.com/4560475/american-automotive-technician-training-live

Given your background, your presence should be felt more in these forums, is that something you might consider working on?

All the best in your career now and in the future.

magnumwhales:
The automotive industry is a wide range of companies and organization involved in design,development, manufacturing and marketing. Millions of people were gainfully employed by enterprises in automotive industry.With these, no doubt about the fact that it is a major industrial and economic force worldwide with very strong influence and importance. However there is a need for young technicians to be well thought" No limit to what you can know",experience technician on this platform can do this by being generous with their library or collection of e-books. There effort and contribution on this section has benefited me a lot as young technician,in fact they are like old wine. Please share your e-books on car remote and key programming, ECU programming,Immobilizer programming ,electrical and mechanical subject. Email alwhayz77@gmail.com. your magnanimity will be highly appreciated.

My advice to you?

Technology is not static.

What will serve your interests best is not ebooks...but participating in current automotive courses run by automotive OEMs.

In case you don't know, e-learning is now the standard format for delivery of educational instructions by car OEMs and not ebooks.

The alternative to automotive OEMs is industry organizations like ASE Education Foundation for the US and the equivalent programs from the Five Eyes.

All the best in your search for ebooks, but given the march of technology those become outdated rather quickly.

An education in yesterday's technology is of limited utility at best.

Not saying ebooks are of no value, all I am saying is be fully aware of their utility and value.

HRtechnique:
Read from top to bottom.
You write those yourself?.
Aren't you in Nigeria?

But please you write soo well.
It's very clear and I think I know the right decision to take now.

When I said my...I didn't mean the thoughts in the Quora link are mine. I meant that you should see the Quora link in the above post by me. Since I have so much to do and so little time to do it, I found someone who said exactly what I wanted to say to you.

I am in Nigeria and I am available for engagements to fix any vehicle issue anywhere that is relatively safe, I delight in taking on vehicles that others have abused and no one wants to touch, that is where I can prove my onions, but this is always for a fee that recognizes the investment in time and brain waves to restore such a vehicle to pristine status.

I am also the anchor of this program https://www.nairaland.com/4560475/american-automotive-technician-training-live which obviously needs to be delivered live.

That said, would you still say that I write so well?

What value would you place on 24/7 online access to the same instructional materials used to train automotive technicians in the United States of America?

Would that not do wonders to your ability to grasp difficult topics? Isn't repetition a prerequisite for retention?

Choose wisely?

Don't be just an OBD II warrior!!

Understand automotive theory and principles of operation through and through.

Would you pay N100,000.00 for classroom instruction only?
or would you rather pay N100,000.00 for classroom and workshop instruction?

and this
