Monitor Description

The ECM receives a signal from the secondary pulley speed sensor [transmission revolution sensor (NOUT)] installed in the continuously variable transaxle and determines the output shaft speed in order to control the gear ratio.

If the ECM detects no signal from the secondary pulley speed sensor even while the vehicle is moving, it will conclude that there is a malfunction in the secondary pulley speed sensor. The ECM will illuminate the MIL and set the DTC.
