Monitor Description

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

The transmission revolution sensor (NC) monitors the output shaft speed.

The ECM commands gear changes and controls the lock up timing based on the signals from the transmission revolution sensor (NC) and throttle position sensor.

If the vehicle is being driven at 25 km/h (16 mph) or more and the speed sensor (NC) signal sent to the ECM is less than 300 rpm, or if the transmission revolution sensor (NC) input signal voltage is less than 0.1 V or more than 1.9 V, the ECM will illuminate the MIL and store a DTC.
