DTC Advanced Diagnostics: P0716
DTC P0716:CVT Input Shaft (Drive Pulley) Speed Sensor A Circuit Range/Performance / Input/Turbine Speed Sensor A Circuit Range/Performance

General Description


The torque converter turbine speed sensor is attached to the outside of the transmission housing. The torque converter turbine speed sensor detects the number of revolutions of the gear on the input shaft and sends a pulsing signal to the powertrain control module (PCM). The PCM converts the pulses to torque converter turbine speed. If no pulses occur with the input shaft rotating, the PCM detects a malfunction that may be caused by an open, an intermittent open, or a short to ground. Based on the correlation between the torque converter turbine speed sensor and the CVT drive pulley speed sensor, the PCM detects a malfunction and stores a DTC.

[ ]: HDS Parameter

Malfunction Threshold
The rotation speed [Torque Converter Turbine Speed] measured by the torque converter turbine speed sensor is less than the rotation speed [Input Shaft (Drive Pulley) Speed rpm] measured by the CVT drive pulley speed sensor by a factor of 0.56 for at least 10 seconds.

Possible Cause
NOTE: The causes shown may not be a complete list of all potential problems, and it is possible that there may be other causes.
Torque converter turbine speed sensor line open (includes connector loose connection or disconnection)
Torque converter turbine speed sensor line short to ground
Torque converter turbine speed sensor failure
PCM internal circuit failure

Confirmation Procedure
Operating Condition
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.
With the HDS
None.

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

Conditions for clearing the DTC
The shift position indicator comes off by turning the vehicle to the OFF (LOCK) mode. 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 12 volt battery.
