Well said but i do not know where ti find these people.

So stuck mehn..

Tow it to Gazzuzz workshop

DukeNija:
Please I need expert opinion on a car I want to buy. It’s a Toyota Matrix. I scanned the car and this code came out p0012 camshaft position sensor Bank 1. Should I run away? Please help

Not a good decision to use a mere scan DTC to make judgement if a car is good or not for purchase .Get an expert to do a complete inspection check for you.

How can I easily identify upstream from downstream sensors so as not to make the same mistake I made earlier...?

Use part number

i noticed voltage on d downstream sensor is abt 0.4 - 0.7V. i believe this one is a narrowband sensor right
Yes cos the primary reason for the downstream is for catalyst monitoring ,fuel management is secondary (upstream is basically fuel management) and using wi
de band for such purpose will not be cost effective (wide band is more sophisticated and expensive) when narrow can readily serve the purpose .
I am yet to see a a manufacturer that will wide band for downstream !!
now my question is can a person use narrowband sensor to replace d upstream (wideband) sensor?
No Sir ,unless you want to change to ecu that support narrowband upstream like the 1999 downward model which just like downgrading your fuel management to worse than before .
Upstream is upgrade of narrowband for better fuel management and to achieve near zero emission standard .

OgaKazeem:
My ogasnin d house. please i need your help with a diagnosis. Been doing little tune ups and maintenance on a 2001 toyota camry. Since the time i can remember, whenever I check the output voltage from the upstream O2 sensor I have always gotten a reading of 3.xx V. However, checking online I saw that the normal voltage shoud be between 0.1V and 1.0V at worse. Yesterday i got another O2 sensor just to confim, i got the same reyading. Now the crazy thing is when i disconnected the O2 sensor, though the Check engine light came on (P1135 error code or so)... funny thing is ECM was still reporting a reading of 3.xx V even while the sensor was disconnected. Pls how do I resolve this? Where do I start from?

Don't get yourself confused ,what you need the basic operation ubderstanding .
there are two types of O2 sensor narrow band and wide band .Narrow band typically switch from 0V to 1V to react to air fuel mixture variation and relies on voltage solely to achieve this whereas wideband sensor uses current to follow air fuel variation and the small 3.3V -3.*** V voltage margin is used to represent the wide margin of current fluctuation(this might sound a little bit complicated) which is why the voltages fluctuation is small.
Toyota is one of the early adopter of wideband O2 sensor so that which is the reason for your car 3.×× v values ranges ,it is using current internally to respond to air fuel ratio variation but voltage can only varies in corresponding small step to depict this.
The ecu uses the sensor current variation to make fuel trim adjustment and diagnosis .
From my own practically experience ,the sensor voltage stays between 3.3v -3.28v when the sensor is not working regardless of various instances of fuel and air variation .
The voltage can peak up to 5V at extreme lean condition and go as low as 2V when fully rich but stays around 3.28v -3.21v at idle condition which is totally a different rules u get in narrow band ones that you read about in books and YouTubes.
I will soon upload some live practical pids pix when I am less busy

Wrichies:
Pls where can I get an ultrasonic fuel monitoring sensor here in Nigeria

Depending on the area of application .

m4goodlife:
Thanks for the comment.

Sincerely, i love Toyota, but like I said earlier in the post, I'm constraint with cash. The Lowest price i got for the corrola is 600, which is above my budget of 500.

If your choice of Nissan is cos budget constraint ,you just made a bad decision .

babalonimi:
My problem s removing camry 2002 filter required removing entire dashboard. The design s awkward. Pls wat can I do without removing d dashboard cos my Ac s performing below standard? Experts pls

If your ac is performing below standard ,how do u conclude that removing filter is the solution.

Thanks for the reply.
It cranks well but doesn't start. At times if it starts luckily it doesn't idle well and dies immediately after trying to press the throttle. Also, in some cases, it doesn't want to climb up hill or anything no matter how high or low.(that's when it still start o, for now no starting at all but it cranks)

What is the repair history of the car to fix this issue apart from scanning .

tobiuseful:
Good day,
Please I need an expert advice from my ogas here about my Mazda 626 2002 millennia that won't start in the morning. It has been worked on by rewires and mechanics but the problem still persists.
I got it scanned and I got the code P0743 ( Torque Clutch Converter Electrical) persistently. Other codes scanned has been worked on and cleared.
My mechanic told me to change the transmission or replace it with a manual transmission.
Please I'll like to know if the problem is repairable without changing the gear and also if that particular code can cause my car not to start.
Thanks.

No relationship at all .Provide more information about the issue ,is it a no- cranking or no starting issue

Taking my data for with that car ,even without catalyst ,your MPG will average around 24mpg ie 10km per litre which prove that absence of catalyst for that model of car is not significant .
If you experiences poor fuel mileage with your corolla ,look beyond catalyst for the culprit.

MMM

I also get goods with UC logistics too. Anybody who knows whereabout of uche should help

U need to work on your perspective cos whatever you are enjoying today some people pays for it even with their life .You had better keep quiet and pursue your own purpose than making fun of people leave this earth better than the way they met it.

codehead777:
Thanks, I planned doing that. Do you have an idea of a diagnostics center around surulere?

All this so- call diagnostics na waste of money ,look for any tussh ,english speaking mechanic aka alakowe mechanic like Gazzuz ,mayor123 , etc

There is a saying that states "Science informs but Story transforms " there is nothing like a good story line to pass across important message and to spice up the weekend.
Thumbs up to Gazzuzz!!

opomulero:
good evening my people,
please what is the normal rpl of eod 2003 @ idle and normal rpm when AC is On.

mine is @ 1000 rpm idle and @500 rpm when AC is on.

when d AC is On the engine will be shaking a little.

is this normal.


Secondly,
the eod has single cell radiator and the fan starts rolling when the key is on ACC.
i thought d fan should pick up automatically when its hot enough..what can i do to rectify this issue.

kindly assist cara expert in the house.

Idle will get to normal (650-800RPM) after you have connected the fan to default configuration and reinstall your thermostat.
Then your idle control valve is clogged with dirt which is why your idle is going down with load so service the idle.
Lastly avoid Kazeem like plague

iamolufemi:
Good evening house. I drive a 1998 Toyota avensis and I just changed d AC compressor but the engineer never mentioned changing the condenser. After leaving his workshop that same day my new compressor hooked and stopped working. But his observation was that the condenser is dirty and damaged and needs to be replaced because it gave d compressor much stress.
Please how true is his suggestion?
Thanks

How true like how ?what technical diagnostics data have you provided for anybody here to make any definite advice .Get Ac manifold readings and post it here.

I doubt If you have ecu issue what you have is electrical issue ,your ecu is offline which is the reason your security flag is permanently on .
Install your old ecu back and get a professional technician and not a rewire o ; someone skilled in reading and interpreting wiring diagram to check this for you .

Unless NBC SKYE changes it's ways..... Please think twice before using them

That daniel guy is always forming busy and don't respond to chat

cmoney22222:
Thanks sir

Check if the RPM needle is flickering upon starting to confirm if it is fuel or ignition issue.
I doubt if it is the battery cos op confirm that another one has been used to check it but to no avail

pappy2000:
I need a mechanic who can help me change my Chrysler Voyager 2002 engine from 24 to 2.0

Seems u want to embark on a white elephant kazeemisation project cos there is nothing like 2.0 engine variant for voyager for that model year unless you want to manufacture one for yourself.
But if I may ask ,why seeking for such impossible downgrade of engine capacity ? Fuel consumption ?

Gallass:
No communication with ECU

I doubt this ,it was scan tool that was used that cannot understand the protocol.
Early model Nissan/Infinity cannot work with Generic scan/Obd2 tool except OEM
Look for a more professional scan tool

xtivin:
If you are on single cell, don't bother replacing it coz it was removed to avoid over heating. Other wise upgrade to a double cell radiator. If it's your first car and you are scared because of check engine, then be ready to keep paying engineer for scanning because the check engine will still show for another issue especially if it's naija used.

How does changing to double cell solve the issue at hand ,seems u know more than the manufacturer that spent millions of in R & D that design single cell radiator for that vehicle. Stop complicating simple issue.

help.. my Nissan almera car overheats.. all fans are working and my radiator has been washed with coolant poured in as well but all to no avail as the gauge can go as high as the red part

If you have gotten this issue for some considerable length of time ,there is high tendency for your headgasket to have broken as well .So you need to look beyond headgasket issue but the root cause of the overheating which is usually leaks 90% of the time .
Look for a reputable techie to perform cooling system test and stop running your fan direct again.

HenriXI:
If i could get live data from the ABS wheel speed sensors, i believe YES! There's communication with the ABS module.

Check it out on the Foxwell scan tool picture attached.

What do you think?

You have modules communication issues via the instrument cluster ,PCM is unable to retrieve VSS successfully from abs modules probably due to instrument cluster issue
To confirm this ,use a professional scan tool to scan the PCM module and confirm if you a have corresponding VSS values that is same as abs VSS.
Note that ABS is the source of VSS for other modules and the instrument cluster is the gateway modules for other the vss in that particular model of vehicle.

Toks12345:
Hello Somebody
I just observed that my 1998 Toyota Camry speedometer needle is not moving and remained at point zero even as I accelerate harder.
what could be the cause of this, please I need your help

Tell your techie to confirm vehicle speed signal from the vss on the transmission and if unavailable ,confirm wiring integrity and sensor.

"Sensor brainbox and open brainbox " any auto technician that say such doesnt deserve to open a car toy not alone a real car electrical system .
