Car Forum / Chrysler Cars / September 2004PT check engine light
'01 PT check engine light came on, ran rough,determined #1 not firing. Replaced plug, runs great now, smooth as before. BUT check engine light is still on. Shouldn't it go out now, or does it have to be somehow manually reset ?

The Task Manager program in the PCM (Computer) needs to make a full diagnostic cycle before it will go out. If it doesn't go out in one tank of gas usage, you may want to take it to the stealership and let them reset it with their scantool. > '01 PT check engine light came on, ran rough,determined #1 not firing. > Replaced plug, runs great now, smooth as before.
