Your 1994 dodge spirit check engine light - using on off on off on off on method - indicates codes 12 and 37 - what could be wrong with it?

This is for a part lock/unlock throttle control circuit. The brain of the trans. I'd reset the battery, disconnect for 5 mins, then rescan after driving so the car gets hot and cold and relearns as to reset the IM monitors. If problems are still present, then it will show up again.
