Please I need a lasting solution or advice based on who ever has experienced it before.
Am using a vw touran 2005 with an Fsi engine 2.0.
At first I started noticing after 15 minutes drive ,the car will flashing a check engine light and it will be jerking as if the plugs or coils are not working.
But after the scan was done ,it was not a misfire but and (injector 1 cylinder open circuit).
We brought out the injectors and service them and the seem to be fine .
Now we took the Injector 1 and send it to cylinder 4.
Started the car and it ran for 15 minutes and the jerking came back again .we scanned it again and it still showed injector 1 cylinder open circuit again.
Rewire is suggesting we change the ecu brain box that it might be the problem.
Since we check the socket wirer to the injector and it was good and tight.
Rewire is suggesting and ecu replacement..
Please I need help on this issure

Change your mechanic and go for labscope non- invasive engine dynamics test .Both electrical and mechanical elements will be taken care in Jst one reading all within 10 minutes or so less .Troubleshooting has gone high tech and sophiscated with 21st century testing method ,Disruption has already taken over the industry, unfortunately our so -called technician are still living in the dark ages of "check this check that syndrome ".

Can this make the a.c not to even come on at all? It's not that it comes on but doesn't get cold, it just doesn't come on at all

I am still referring for the ac that come on but doesn't get cold.The way it works is that the ac computer need to some set of appropriate input signal to make the decision to turn on the compressor or not and there is likehood of ac computer not seeing input evaporator temperature signal or the right pressure of refrigerant pressure signal which are major determinant input signal to turn on the compressor.

adahib:
Good afternoon all.
The AC of my 2007 Camry has refused to come on. The electrician has checked all the fuses and relays but they all seem to be working. We have even gone as far as getting two different control knobs but they still didn't work.

As it stands the electrician has no idea how to proceed.

Please if anyone has any idea what the problem could be, I am very willing to listen.

Thank you.

Check the evaporator temperature sensor.

Dozieson:
you need a scanner to scan your car when you see any check light
for oil pump, you will see the symbol on your instrument cluster

Scanner is useless on this case o ,u need more advance tools and this is beyond diy

theForth:
Hello namesake, where can I get the car scanner?

Any link?

Scanner to do what ? Scan oil pump .
U better look for a more competent technician to do a thorough investigation and test.

Blackbishop:
2 things are involved, 1. Crankshaft Position Sensor.
2. ECT Sensor

Finally toook it to a coolant specialist, he did diagnosed it and noticed it’s one of those nuts that go rust and needs changing , he did change it and everything is working perfectly well now

Thanks for the feedback .

Grupo:
Ah!

All the times I disobeyed that rule, I paid for it.

Well, may not apply to everything.

But are you encouraging indiscriminate changing of gear oil knowing that something could go wrong if not done well.

Not Indiscriminate but scheduled change of oil ,refer to as maintenance.

Grupo:
If it's not broken, don't fix it.

That is not applicable in every instance o cos if u wait till u it broken,fixing might not be possible again .

ReformerD:
Good day house, I hope someone sees this and respond , for the past few days I noticed my radiator water always go down( low) which seems so kind of strange , with that effect, I tried to topple my radiator with another water but I noticed after driving for awhile , I noticed water and coolant leaking underneath the car which I tried to call my mechanic and told him about it , I took it to him for checking , he said maybe the radiator is dirty and needs so cleasing which he did but still the same thing, please what can I do stop fix this …. The water inside my radiator do go down on time and it’s showing some leaking underneath

Car name is Kia Optima 2013

Find a technican that has a coolant pressure tester to troubleshoot the leak .

engineer4mos:
Please kindly share your experience with me.
I am seriously experiencing peperish smoke from my car, Toyota Camry Pencil Light V6 Engine.
Oxygen Sensor changed, Nuzzles changed, plug changed, Airflow meter is okay according to my mechanic but when I run at 100km/hr that hot peperish smoke will show face. Engine is not shorting oil rather it goes above the guage on daily check.


Please what could be responsible for this?

What is the colour of the smoke ,if black then u have fuel metering issue and can be due to ecu receiving faulted sensor signal.
Change your mechanic and look for good technician that is good @ diagnosis to help u with this

xavuv:
Hi guys

Recently i noticed that my engine does not start at once in the cold morning, cold afternoon or cold evening. It takes 2-3 cranks before the engine comes to life.

However, on warmer mornings or afternoons or evenings - the engine starts at once but with initial shaking/vibration of the engine but this disappears in about 3 secs.

This problem, engine refusing to start at once, only happen at first engine start of the day. Every other starts during the day are fine.

Again, Sometimes during driving, at hold ups and at any time of the day, the RPM needle goes below 0.8, like between 0.4 -0.6, and still the engine would not shut off.

Car drives fine, transmission in good shape.

What could be the problem, what is the fix?

Car is camry 2005
2az fe engine

Post any troubleshooting technical data that u might have retrieved here eg ,scan codes ,data etc etc

Alphil:
Good evening housemates!
Here I am again with the complaint of my Honda City 2007 edition still vibrating like a mountain about to experience earthquake. Engine seats checked and changed, carburettor flushed, spark plugs and plug cables considered, engine oil changed, etc, but the problem continues. Getting fed up. I need help.
Thanks

Change your mechanic and go for deep diagnostics .

Shinanny:
Good morning boss, am one of ur followers on nairaland. Boss pls I have a nissan altima 2005, when driving this car suddenly the acceleration pedal will not move well on motion, I have to off the engine for some time and start again. I asked my mechanic who said I have to change the gearbox that the course is from the gearbox, pls hw true is this

If you have to switch off the vehicle on failure to for to regain better performance on motion then u don't have gearbox issue ,what u have is drivibility issue. Go for deep diagnostics (not mere scanning ).

Musabua:
No issues. I just decided to help him scan the car because I saw his check engine light & I have a scan tool I bought for my own car.

If no complain of any drivibility issue or high fuel mileage ,then erase the codes and check the fuel trims .

Ifebazz:
Ooh, but when I was running the engine yesterday, I noticed that once the AC is on, the fan is on, but I thought the fan comes on automatically when the AC isn't on. But anyways, thanks for the heads up, I will see if I can change the fan or thermostat. You guys are very dependable.

Your fan is normal that way, don't tamper with any yet .What u need to emphasis is to properly monitor the situation whenever the issue came up and try to confirm what is not working.

GAZZUZZ:
The codes are cause and effect.

Between the intake manifold and the airbox is an air leak. Unmetered air entering into the system bypassing the airflowmeter causing a system too lean code.

Just check the intake side for a leaking vacuum hose , or hoses not plugged in properly , clear codes after that and rescan after a day or 2 of driving

Wrong sir. This assumption has been taken too far.

Musabua:
Oga Gazzuzz and other gurus in the house. Pls help. A friend of mine uses Camry 2007 and here are the codes after scanning.

What issues are u experiencing is what really matters

t2sco:
Morning good people. Pls hv been using total oil but my mechanic ask me to change it to HARDEX. PLS IS HARDEX BETTER THAN TOTAL OIL?

Total ,harder are brand name that produces many kind of oil ,what matter is the viscosity of oil u are changing to .Is that your vehicle a Keke marwa?

okoroemeka:
if the ignition coils are good ,the spark plugs are good and nozzles are firing,what else do you think that can make 3 cylinders in one bank of a v6 engine to stop working?if it is not valve what else can cause such problem?and what can make the valves to fail at once,if not poor lubrication,I have worked similar problem in my previous car that's why I know.

Since my audience here is a diyer with his only training and learning based solely "on working on similar problem on his car ",and his mind so closed to accept superior knowledge ,I think I am done ,no comment .
Continue to wallow in your "knowledge"

JAYUK:
Kindly advise me on what to do, my vehicle a 2012 Sienna cools only from the front passengers vent, after a while the drivers side will feel as if it's cold,the tech guy added more gas nothing changed, he wants to check suction valve and condenser blockage. please am scared of dismantling the vehicle,he further said the compressor would pack up if not fixed, please assist me

Check the pressure reading of the system with manifold Guage to confirm the system integrity if it ok ,then check the blend doors.

Good evening Seniors, please I have issue with my Nissan Pathfinder 2001 model. I noticed that the engine wasn’t complete so I took it to my Rewire to help me service/changed the Nozzles to a Tokunbo and we changed the 6 plugs too but still the engine didn’t work well. We later discovered that it’s only 3 cylinders that are working out of the 6. And this have given us worried of what could have happened and this led us to even changed the brain box but no luck yet. So we suggest that we should scanned the car to know where the problem(s) is. The scanner said the problem is P1165 which is Swirl Control Valve Control Vacuum Switch. I don’t know what to do anymore. Please my brothers help me out because I’m really losing out on this car. Thanks

3 cylinders just going down like that is not mere
coincidence but certain denominator that is common to all 3 cylinders that is affected ,if it restricted to a single cylinder bank then it time to check the following item:timing ,power feeds and ground to the ignition and injector etc

okoroemeka:
if the 3 cylinders that are not working from one bank of the v6,it is time to bring the one top cylinder down and change the valves,also check the ignation coils if it is firing, mostly the cause of this type of valve failure is poor oil pressure getting to the top cylinder,let them bring out the bottom plate and wash the oil pump filter to increase pump pressure

Bad suggestion.
Don't ever start opening up engine indiscriminately based on mere what u feel but what u have confirmed 100%.Beside poor oil pressure will affect all cylinder not just 3 cylinder alone .

donuba61:
Good morning bro. These are the two brain box numbers. New brain box 37820RNAY83384911891
Old brain box: 37820RNAY844780124403

The new ecu is a right replacement, check other components

If the 3 cylinders that are not working is restricted to a particular bank then let your tech check the components that are common to bank eg valve timing or power or ground feed to ignition and injector etc

Scot1255:
Pls check The images for scan result. My mechanic doesn’t really know what to do.
Kindly help

Change your mechanic

obidevine:
The major problem I've been facing is engine stalling while driving. I've changed fuel pump but problem still persists

Oga ,are still on this same issue

obidevine:
For Gazzuzz the genius to refute what Autologic is saying , omoh I don dey fear if Autologic really sabi work oohhh.

Me, I am a seeker very open for learning and even correction .I never sabi anything o

GAZZUZZ:
To remove the wheel speed sensor On a corolla you need to remove the wheel hub sir. That's a total waste of very valuable time and resources.

A simple multimeter to check resistance is quicker.

I assume my audience is diyer that doesn't have experience in testing and not equipped with modern tool,beside resistance test is not even a reliable test .

KolaShangOne:
C1333.

Open circuit in left rear speed sensor

To confirm if the issue is from sensor or circuit ,swap the left rear sensor to good side and confirm with scanner if the same problem shows on that side too.

DukeNija:
Or oil level.

Cannot be oil level cos it will be felt already on braking
