Passat (B6) :: How To Test If Check Engine Light Is Working
What's the quickest way to check if the Check Engline Light is working?
I took my passat to get apr chipped. The shop spent few hours, and even worked with APR, and they could not figure what the issue is.
They were able to upload the software fine, but couldn't figure out which mode it is in, as they say my CEL isn't flashing, and therefore unable to switch modes.
APR got the shop to flash back the original software, and had them do a 'test'. I was told they tried unplugging a sensor, and the CEL didn't show, and made the conclusion that there is an issue with my ECU, which got me worried.
I am guessing they unplugged the MAF, as it is the easiest/closest sensor to unplug. And from what I read, it might not throw a CEL. In addition, APR's website state some B6 Passat Auto only support 1 mode.
Is there any easy way to test if my CEL is working or not? It lights up for a quick sec when I start the car, so I know it is not a fuse or bulb issue. Could it really be my ECU that is faulty? or is my ECU working ok, but only support 1 mode?
Passat (B5) :: 1999 - Failed Emission Test
I recently failed emission test for my 1999 V6 Passat. I replaced the cats., thermostat, O2 sensors (before cats), and the list goes on. Is there a reflash in the ECM that needs to be reset that only VW can do with their scanner?
View 4 RepliesLincoln - Towncar :: Check Engine Light Came On - Emission Leak
1997 Lincoln Town Car, We had an accident three years ago in which the right rear wheel was destroyed and the axle bent. They were replaced. . Shortly afterwards the check engine light (emission leak) came on. My local mechanic thought he found and repaired the problem. It came on again. We changed the gas cap. No dice. The local Lincoln dealer did a smoke test and decided the problem is the SOLENOID ASSEMBLY CANISTER VENT. But the part is obsolete. An after market part did not solve the problem and neither did a used part the dealer installed. The car operates normally but I won't be able to pass inspection.

I have an 07 Impala. Just recently, the engine light came on. I contacted OnStar who did a vehicle diagnostic and told me the problem was the emission control and further told me I should tighten my gas cap which might take care of the problem. It didn't. How important is it to take care of this?

I have a 2005 Ford Escape 3.0L V6. The emission systems/check engine light keeps coming on. I have taken it to 4 different places and the diagnostic keeps referring to the MAP Sensor. It has been replaced twice (granted one was free) and the light is still on. I have also replaced a coil, the plugs and boots.

Chevrolet - Equinox :: Check Engine Light Is On For Evaporative Emission System Leak Detected
I have a 2008 Chevy Equinox, and recently I noticed a gas smell...I saw Chevy had a special policy to replace the fuel pump module, so I took it to the dealership hoping that would be the problem. Fortunately it was, and they replaced it for free. I got my car back Thursday afternoon, drove it Friday, and it sat yesterday without being driven. This morning I drove to the grocery store, and on the way home my check engine light came on. I have an ODBII scanner, so I plugged it in and got this code:
P0455: Evaporative Emission System Leak Detected (gross leak/no flow)
So I was wondering: (1) what is the cause and/or solution to this problem, and (2) is it possible the dealership caused this problem when they replaced my fuel pump module?
It seems awfully coincidental not to be related to the repair, since it is a fuel system problem, but I don't know enough about cars to be sure...
Toyota - T100 :: Check Engine Light On Due To Faulty Emission Evap Control Pressure Sensor
Engine runs perfectly but "check engine" light" stays on due to faulty Emission Evap control pressure sensor (P/N; 89460-0w020). Problem is Toyota no longer makes this part and there is no after market for it. It appears I may have to "junk" a perfectly good truck.

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......

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.
View 2 RepliesPassat (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?
