Steering Angle Sensor: Service and Repair
Steering Wheel Rotation SensorSpecial Tool(s):
Removal
1. Remove the clockspring. For additional information, refer to Air Bag Systems.
2. Remove the 2 steering wheel rotation sensor bolts.
3. Disconnect the steering wheel rotation sensor electrical connector and remove the steering wheel rotation sensor.
Installation
1. If the arrow on the steering wheel rotation sensor ring and the arrow on the sensor housing are misaligned and/or the straight ahead position of the sensor is not known, follow these steps to align the sensor prior to installing the sensor:
1 Orient the front wheels in the straight-ahead position.
2 Connect the steering wheel rotation sensor electrical connector.
3 Connect the battery negative cable. For additional information, refer to Battery.
4 Carefully rotate the sensor clockwise until it stops.
5 Rotate the sensor counterclockwise 2-1/2 turns.
6 Using the scan tool, read the steering wheel rotation sensor position PID (SWA POS). The PID should read approximately 0 degrees. If not, repeat the procedure.
7 Disconnect the battery negative cable. For additional information, refer to Battery.
8 Disconnect the steering wheel rotation sensor electrical connector.
2. NOTE: Slight rotation of the steering wheel rotation sensor ring is allowed to align the 2 arrows.
Make sure the sensor ring arrow is lined up with the steering wheel rotation sensor housing arrow as shown and position the sensor into the multi-function switch housing.
3. Connect the steering wheel rotation sensor electrical connector.
4. Remove the 2 steering wheel rotation sensor bolts.
^ Tighten to 1 Nm (9 inch lbs).
5. Install the clockspring. For additional information, refer to Air Bag Systems.
^ If the steering wheel rotation sensor was aligned using the scan tool, diagnostic trouble codes (DTCs) will be present in the restrains control module (RCM). Using the scan tool, clear the DTCs in the RCM.
