Pop quiz hotshots.

Someone told me that if the CEL is on, the engine runs on reduced power. True or False. The clock's ticking...........

Thanks people.

FALSE,,,,,,sort of!!! Depends on what DTC the CEL is reporting! If the DTC (problem) can damage the engine, it will cause the PCM to go into reduced power mode. If it is just an emissions related issue NO it will not cause it.

I agree with Bill, it all depends on what the PCM "thinks" is wrong if it will put the engine into reduced power mode.

More than likely you have a faulty gas cap. When you got gas you repositioned it and it sealed. This just happened to me and I just turned the gas cap and the light went out in about 5 mins. I got a new cap.

No oil, no coolant - she's a no run at full power.

The computer is trying to tell you something. Check the codes. Search the forum on how to do do and what the codes mean.
