Monitor Description

WARNING: This page is about a different variant/trim than selected.

The output speed sensor SP2 monitors the output shaft speed. The ECM controls the gear shift point and 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, it will conclude that there is a malfunction of the output speed sensor SP2. The ECM will illuminate the MIL and store a DTC.
