monitor description

The output speed sensor SP2 monitors the output shaft speed. The ECM controls the gear shift point and the lock-up timing based on the signals from the output speed sensor SP2 and throttle position sensor.

If the ECM detects no signal from the output shaft speed sensor SP2 even while the vehicle is moving, the ECM will conclude that the output shaft speed sensor SP2 is malfunctioning. The ECM will illuminate the MIL and set the DTC
