So I noticed the other day that if I go on a long drive which is over 25 miles or something my car's check engine light turns on (exclamation mark) but than when I come home and park it goes away, doesnt show up till I drive to dallas for example from Arlington which about 25 miles.

What could it be? My temperature is normal. Anyone experience this before, i cant see the code because it disappears lol

 

Check the owners manual, sounds like the TPS sensor.

CEL on our cars says "service engine soon"

 

OMG i feel like an idiot, i guess you are right. I completely forgot about that but its weird though that the TPS light on the little digital thing doesnt show anything, usually the little psi thing pops up on it.

weird why it would only show on long drives

 

Mine turns on with long drives as well. I always just figured it was because I put aftermarket wheels on and it doesnt get a signal from the TPMS sensors(They need to be reprogrammed).
