I have the 2.2 liter v-tech engine and when I drive it down the road it shifts fine until it warms up and then downshifts by itself to second gear. The trouble code was the turbine speed sensor circuit A. I tested the ohms on the input and output turbine sensors and they are both within 400-600 ohms. The check engine bulb has been removed by the previous owner but I don't know if that would have anything to do with it or not. I think the TCM may be bad but I need the check procedures to diagnose it correctly on the harness pins. Can you help me please?
