Does anyone know how to turn off the "check engine" light in a 2006? My truck is regularly serviced by a private garage and they don't know the procedure. Thank you.

RE: How do you turn off the "check engine" light i

Time to find a new garage! If you have a 2006 you should be able to swing by any dealership and they can turn it off for you.

This is an old thread, I hope this got resolved. 90% of the time the "check engine light" is caused by a gas cap not being put on tight enough.

a gas cap not being tight enough is sounding like something might needing to be adjusted. i would suggest taking it to a dealership for sure to check on it

With the new US emmission laws, that's the #1 cause of the check-engine lite. Either the gas cap was not put on properly or there is a broken seal when it is put on. Get a new gas cap and see if that helps. I think it can take up to 3 or 4 cycles of running the engine to clear out.

Engine Cycle: Cold start ----> Warmed up ----> Driving -----> Shut off and let cool down.

It can be turned off by anyone with a reader, I believe. Definitely time to find a new shop. Strange that the gas cap being loose results in the light coming on.
