I have a 2005 Acura TL with 82k miles. The car doesn't move on D or M, the engine light is on, and the code says "output shaft speed sensor circuit no signal". How do I fix this?

P0720 Output speed sensor circuit malfunction

Your transmission doesnt use a output but rather a counter shaft speed sensor signal.This sensor is Hall-effect,meaning it measure road speed. If your cant go into gear you need to check for a mechanical condition, engine off,check the transmission fluid,there is a dip stick there measure transmission fluid is its low adds some.also check for transmision leak
