Anybody tell me how to test the speed sensor on on 93 tracer auto trans. speedo works fine. need to check if it is sending signal to pcm. Will it check if ohm meter says no resistance? Have a shift problem where it won't come out of first gear. No power to 1-2 Solinoid from pcm. replaced pcm same problem. Speed sensor must not be sending signal to pcm? can I check with ohm meter?
