Prius (Gen 3) :: Check Engine Light Came On - No Apparent Reason

A month ago my check engine light came on so, after checking to ensure the gas cap was screwed on correctly, I did what the manual recommended and took my car directly to the dealership. After paying a diagnostics fee and losing my car for an entire day while they ran tests and contacted Toyota, my dealership told me they couldn't find a problem and just reset the indicator.

Within a few days the light came on again but before I had a chance to take it back to the dealership it went off. Now some 3 weeks later it is on again and I'm wondering what to do.

Passat (B6) :: Engine Shut Off For No Reason And Wouldn't Start Up Again

Here's the story, got in my car yesterday and the AC wasnt working, after driving for about 20 minutes in traffic, the AC came back on, about 5 mins and half a mile later, the engine shut off and wouldn't start up again. Had the car towed to the closest garage (not a VW mechanic). This morning, he tried to start it and it fired right up with no problems. He drove it and let it run and everything seemed fine. He ran diagnostics on it and said the computer didn't detect any problems. Picked up the car, and now the AC is blowing hot air, but the engine seems to be running ok.

Passat (B5) :: Check Engine Light Came On After New Engine Installed

Okay, I bought this car used and the previous owner apparently didn't maintain it. So I spent the last couple months having a new (used) engine installed. All said it's been in the shop longer (by twice) than I've been driving it. On the way home from the mechanic the check engine light came on.

If I keep changing my oil every 2000 miles will it sludge again? Dealer recommended every 1500 to 2000 miles! I've spent 15k on this car so far, and driven it about 2k miles......

Passat (B5) :: 2003 W8 - Check Engine Light Came On

I have a 2003 W8 and the check engine light came on today for the cam b sensor... The car has had no problems and drives fine, I do not quite get why all the sudden it is on, and before I bought the car, 2000 miles ago the cam sensor was replaced for inspection, and I drove it for 1000 miles, and now the mil is on and it is running a little ruff... Where exactly on the head is it located? which head would have cam b sensor? I really do not think it is bad again.

Passat (B5) :: 2001 V6 - Check Engine Light On?

I have had a check engine light on in my car for a while now. I am pretty sure that it deals with the disconnection of the vacuum servo that controls the intake manifold's flaps that designate which track the air takes through the manifold. It has been running fine like this for a while under the assumption that because the performance of the vehicle hasn't changed, there is no need for immediate repair.

Here is my new problem which I am trying to determine if it has to do with the above issue. Over the past few days my car has been giving me EPC and ASR lights along with switching to back-up power. I have been on expressways driving 80, i have been going around corners doing less than 20, and it has happened everywhere in between. Keep in mind that when it happens i slip my car into neutral, pull over, and reboot. After that everything is fine for a short while. I stopped at Auto Zone to get a diagnostic, and for some reason, which i did not feel like questioning due to the way the autozone employee was mentally equipped, they did not give me codes, but descriptions.

(1) Camshaft Positioning Sensor Fault A Bank 1
(2) Camshaft Positioning Sensor Fault A Bank 2
(3) PCM Processor Fault
(4) Running too lean on Bank 1
(5) Running too lean on bank 2.

These are the descriptions for the 5 fault codes. I am planning on stopping back today and getting the proper codes. But would like to get some opinions in the mean time. I've check fuses and relays pertaining to this issue and all have tested ok. Nothing is leaking from my engine and nothing is visibly damaged, except for the vacuum servo arm which is broken (see above paragraph). I feel like the issue is with the ECM (PCM, PCM, ECU, whatever).

Another interesting thing is that when i operate my car using the cruise control, there are no issues what so ever. Possibly an issue with the throttle or its many components?

Passat (B5) :: How To Reset Check Engine Light

After I finally got around to replacing my ABS pump I went to get my smog check done. Passed except I didn't drive enough miles to qualify.The SMOG tech told me to drive 150 miles and come back. I drive the 150 plus miles and within that time my check engine light comes on. I go to the shop and have it reset.

How many miles do I have to drive the car after a Check Engine Light reset in order to qualify for a Cali SMOG Check.

Passat (B6) :: Check Engine Light - Air Intake?

I have taken my car into service twice because of the check engine light being on. They fix it and say it has something to do with the intake. It is now on for a third time. Obviously they are not fixing the problem. BTW, I have done no modifications to my car.

Passat (B5) :: Check Engine Light Came On - How To Get Diagnostic

Ok, recently my check engine light came on and i read the code with a cheap-o scanner. It read an o2 sensor code (up stream) i then read it again with a scanner that advanced auto parts offers for use, and it read p 1138 i think. I looked the code up on line and it was a fuel lean bank 1 or something like that. All the info i found sugests a smoke test of the vacumm system. I fist did a visual check of the hoses and also a few burst of carb cleaner and listened for the idle to raise but got no results. I also changed the o2 sensor for good measure, is there anything else i can try before i shell out the cash for a full diagnostic.

Passat (B5) :: Check Engine Light Pop Up - IAT Sensor

I had a check engine light pop up and I went and got it checked out. Comes to be its a IAT sensor or bad connection with this sensor. I change the sensor and made sure the wires on it is all good. The question is, I still have the check engine light up, does the code need to be deleted? And what happens if the code gets deleted and problem is not fixed?

Passat (B5) :: Check Engine Light Came On Repeatedly - Gas Cap?

So I've just come back from the 5th time visiting the dealership for them to clear the "CHECK ENGINE" light off of my dash. Each time they've told me that it is my gas cap....so on the 4th time I bought a brand new gas cap. This time the car drove for 478kms...then the light came on again. I know they are just gonna say EVAP (gas cap issue).

What is the next step? What else could be tripping this fault?

Passat (B5) :: Check Engine Light After Oil Change?

My MIL light came on today for some reason. The owner's manual mentions it may be tied to an emissions problem. I just purchased this car a few months ago and had the oil changed two days ago for the first time. Could there be any connection? What are the most common reasons for the light coming on? I know with other types of cars, that light could mean one of many different things.

Passat (B5) :: 2000 - Check Engine Light On And Off?

Alright so my mothers car is a 2000 passat 30v v6 5 speed and the check engine light will come on and off at random times.
