Advanced Diagnostics - DTC P0717: Problem in CVT Input Shaft (Drive Pulley) Speed Sensor Circuit (No Signal Input)











General Description
The CVT input shaft (drive pulley) speed sensor is attached to the outside of the transmission housing. The CVT input shaft drive pulley) speed sensor detects the number of revolutions of the gear on the drive pulley and sends a pulsing signal to the powertrain control module (PCM). The PCM converts the pulsing signal into drive pulley speed. If no pulses occur with the drive 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 correlation between the CVT input shaft (drive pulley) speed sensor and the crankshaft position (CKP) sensor, the PCM detects a malfunction and stores a DTC.

Enable Conditions






Malfunction Threshold
The drive pulley speed measured by the CVT input shaft (drive pulley) speed sensor is 100 rpm or less for at least 3 seconds when the engine speed measured by the CKP sensor is 600 rpm or more.

Driving Pattern
1. Start the engine.
2. Drive the vehicle at a speed of 19 mph (30 km/h) or more for at least 30 seconds.

- Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.

Diagnosis Details

Conditions for setting the DTC
When a malfunction is detected, the MIL comes on and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the PCM memory.

Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command or by disconnecting the battery.
