Steering Angle Sensor: Testing and Inspection

Memorizing the Torque Sensor Neutral Position

The torque sensor neutral position must be memorized whenever the steering gearbox or the EPS control unit is replaced. Note that the torque sensor neutral position is not affected when erasing the DTC.

NOTE: The torque sensor is temperature sensitive. When memorizing the torque sensor neutral position, the ambient temperature must be above 68 °F (20 °C).

1. With the ignition switch in LOCK (0) or with the vehicle ignition in the OFF mode, connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.





2. Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.

3. Make sure the HDS communicates with the vehicle and the EPS control unit. If it doesn't, troubleshoot the DLC circuit Testing and Inspection.

4. From the EPS MENU, select MISCELLANEOUS TEST, then TORQUE SENSOR LEARN, and follow the screen prompts on the HDS.

NOTE: See the HDS Help menu for specific instructions.

5. Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
