    Do I need a crank sensor relearn?

    I just COMPLETELY rebuilt my motor. New crank, cam, rods, pistons, etc...I am awaiting a tune because it stalls. Anyways. A dealer said I will need A crank sensor relearn since I pulled the motor or it will throw misfire codes. Is this true?

    Thinking that's correct - is the car throwing codes? Could throw random misfire or a CKP code.

    It hasn't ran long enough to get a good read on it. Mind you I dont have a dialed in tune yet so I have to get it tuned before it will idle on its own because of the after market cam

    Just got a basic tune, I read on the website you just gave me hat if the pcm has been reprogrammed(tuned), you dont need a crank relearn...True?

    Alot of people/tuners turn that code off. Does not interfere with the performance of the vehicle what so ever.
