Steering Angle Sensor: Service and Repair
Torque Sensor ReplacementNote these items during replacement:
- Do not allow dust, dirt, or other foreign materials to enter the gearbox.
- Do not try to disassemble the torque sensor assembly. If the torque sensor is faulty, replace it as an assembly.
- If the torque sensor is replaced, the EPS control unit must memorize the torque sensor neutral position.
1. Center the steering rack within its stroke.
2. Remove the torque sensor assembly (A).
3. Coat the new O-ring (B) with grease, and carefully fit it on the torque sensor housing.
4. Apply grease to the needle bearing (C) in the gearbox housing.

The alphabet stamping (for example "AB") (D) on the pinion shaft aligns with the rack guide screw (E) when the rack is in the straight ahead driving position.
When installing the torque sensor assembly, make sure the "alphabet" stamping ("AB") is within the range.
