Symptom 00

DTC C0460 (Symptom 00)

Circuit Description

The steering wheel position sensor is a 5-volt dual analog triangle signal device which is used to sense the steering system's center position to provide equal return to center and on center feel. The valid signal voltage range of the sensor is 0-5 volts. The sensor's 2 signal voltages will increase and decrease within the valid signal voltage range and stay within a voltage range of each other as the steering wheel is turned.

DTC Descriptor

This diagnostic procedure supports the following DTC:

DTC C0460 Steering Position Sensor

This vehicle has DTCs which include DTC symptoms. For more information on DTC symptoms, refer to DTC Symptom Description.





Conditions for Running the DTC

* The ignition is ON, with the engine ON.
* Power Steering System voltage is 9-16 volts.
* Slight amount of steering input

Conditions for Setting the DTC

* The steering wheel position sensors signal 1 and signal 2 voltages are greater than 2.5-2.8 volts of each other.
* A short to ground, short to voltage, or an open in the steering wheel position sensor, or the circuits to the sensor.

Action Taken When the DTC Sets

* DTC C0460 00 is stored in memory.
* The DIC displays the POWER STEERING warning message.
* Reduced steering assist performance.
* No return to center

Conditions for Clearing the DTC

* A current DTC will clear when the malfunction is no longer present and the steering wheel has been turned 1 full revolution.
* A history DTC will clear after 100 consecutive malfunction-free ignition cycles.
* Using the scan tool

Test Description

The numbers below refer to the step numbers on the diagnostic table.

2. This step tests if the sensors signal 1 and signal 2 voltages are within the valid range of each other in their active state.
4. This step tests if the malfunction is internal to the PSCM.
9. This step tests if the torque/position sensor harness is damaged. Since both ends of the harness can not be accessed, only visual circuit inspection can be performed.
