DTC P0722: Problem in CVT Output Shaft (Driven Pulley) Speed Sensor Circuit (No Signal Input): General Description

The CVT output shaft (driven pulley) speed sensor is attached to the outside of the transmission housing. The CVT output shaft (driven pulley) speed sensor detects the number of revolutions of the gear on the driven pulley and sends a pulsing signal to the powertrain control module (PCM). The PCM converts the pulsing signal into the driven pulley speed. If no pulses occur with the driven pulley rotating, the PCM detects a malfunction that may be caused by an open, a temporary open, or a short to ground. Based on the velocity ratio measured by the CVT output shaft (driven pulley) speed sensor and the vehicle speed sensor, a malfunction is detected and a DTC is stored.
