MVD 5 Speed - Automatic Transmission

DTC P0717

Circuit Description

This sensor detects the rotation speed of the input turbine. By comparing the input turbine speed signal (NT) with the counter gear speed sensor signal (NC), the engine control module (ECM) detects the shift timing of the gears and appropriately controls the engine torque and hydraulic pressure according to various conditions. This provides smooth gear shift.

The ECM terminal 125 detects a revolution signal from the speed sensor (NT) (input RPM). The ECM calculates a gearshift comparing the speed sensor (NT) with the speed sensor (NC). While the vehicle is operating in 2nd, 3rd, 4th or 5th gear in the shift position of D, if the input shaft revolution is less than 300 RPM although the output shaft revolution is more than 1,000 RPM, the ECM detects the trouble, illuminates the MIL and stores the DTC.

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC P0717 Turbine Speed Sensor Circuit No Signal

Conditions for Running the DTC

The engine is running.

Conditions for Setting the DTC

The ECM will set the DTC if the following conditions are present:

* Vehicle speed is 50 km/h (31 mph) or more
* Park/neutral position switch (NSW and R) is OFF
* Speed sensor signal is less than 300 RPM

Action Taken When the DTC Sets

* DTC P0717 is a type C DTC.
* The malfunction indicator lamp (MIL) illuminates the first time the diagnostic runs with the fault active.

Conditions for Clearing the MIL/DTC

The DTC will clear when conditions for setting the DTC have been repaired.
