frown Check light

Does anyone have any ideas on why the "check light" light illluminates? My truck had one show up yesterday, but there seems to be no problem with the way my truck runs or drives. Can it illuminate when you are running low on coolant???

Re: Check light

Any number of reasons might trigger the light.

A loose spark plug wire or???

Most cars/trucks show the light after a set number of miles. If it were serviced at a dealer or reputable shop, they would reset the ECU after retrieving the codes during normal maintenance.

I'd disconnect the battery for a few minutes and then see if it comes back on.

Re: Check light

Your best would be to either take it down to Ford to let them pull the codes or, if available, take it down to one of your local parts houses. Nearly all of them will pull the codes and interpret them for you for free. There's a whole lot of things that could cause the light to illuminate and to try and figure it out without any driveability problems is a tough chore.

Re: Check light

Most of the time it's a bad O2 sensor in my experience.
