Removal Procedure

    Caution: Refer to SIR Caution in the Preface section.

  1. Disable the SIR system. Refer to SIR Disabling and Enabling.
  2. Remove the lower dash insulator and knee bolster.
  3. Remove the intermediate shaft from the steering column. Refer to Intermediate Steering Shaft Replacement .

    4. Important: Do not apply force to the sensor and the bearing assembly in a sideways direction.

  4. Remove the sensor electrical connector by using a suitable tool in order to pull the connector down around the right side of the steering column for accessibility.
  5. Remove the sensor retainer from the steering shaft.

    6. Object Number: 835301 Size: SH

    Important: When reusing the sensor (1) you must install a pin into the sensor before it is removed from the steering shaft. By not installing a pin into the sensor it will cause the sensor to lose its centering position and must be discarded.

    Pin diameter must be in the range of 1-2 mm.

    Do not remove the bearing adapter (3).

  6. If reusing the sensor (1), remove the position sensor by pulling the sensor straight out from the bearing adapter (3) until the sensor is almost off the steering shaft (2). Install a pin into the sensor before removing from the steering shaft (2). Do not remove the pin until the sensor is re-installed.
  7. If replacing the sensor (1), remove the sensor by releasing the tabs on the lower bearing adapter. Pull the sensor straight out from the bearing adapter (3) and off the steering shaft.

Installation Procedure

    Important: A new sensor must come with a pin installed. If pin is not installed, return and reorder sensor.


    Object Number: 835314 Size: SH

    Important: Do not apply force to the sensor (1) or the bearing adapter (3) in a sideways direction.

  1. If reusing the sensor, with the pin still installed, align the sensor onto the steering shaft (2) and into the bearing adapter (3).

    2. Important: If installing a new sensor the sensor will come precentered. Do not remove the pin until installation is complete.

  2. Install the sensor onto the steering shaft (2) and into the bearing adapter (3).
  3. The sensor must be set to approximately 3 mm gap between the sensor and the bearing adapter.
  4. Install the sensor connector.
  5. Remove the pin from the sensor.
  6. Install the intermediate shaft to the steering column. Refer to Intermediate Steering Shaft Replacement .
  7. Install the lower dash insulator and knee bolster.
  8. Enable the SIR system. Refer to SIR Disabling and Enabling.
