Monitor Description

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

If the ECM detects no signal from the transmission revolution sensor (NOUT) even while the vehicle is moving, it will determine that in the transmission revolution sensor (NOUT) is malfunctioning, illuminate the MIL and store a DTC.
