Power Steering Motor or Torque Sensor Replacement
| IMPORTANT | The power steering control module is serviced separately from the steering column assembly. However, the torque sensor is serviced as part of the steering column assembly. |
After replacing either the steering column assembly or the power steering motor only the Steering Position/Torque Sensor Calibration procedure must be performed. Certain steering symptoms can be corrected by performing the Steering Position/Torque Sensor Calibration procedure such as
- Poor or uneven return to center
- Poor or uneven on center feel
