Output Speed Sensor Circuit Short to Battery (P072012,P072014,P072031)
DESCRIPTION
This sensor detects the rotation speed of the transmission output shaft and sends
signals to the ECM. By comparing the input turbine speed signal (NT) with the output
shaft speed sensor signal (SP2), the ECM detects the shift timing of the gears and
appropriately controls the engi ...
