Torque Sensor Neutral Position

The EPS control unit stores the torque sensor neutral position in the EEPROM. The torque sensor neutral position must be memorized whenever the steering gearbox, or the EPS control unit is replaced.

Note. The torque sensor neutral position is not affected when erasing the DTCs.

Memorizing the Torque Sensor Neutral Position

The torque sensor neutral position must be memorized whenever the steering gearbox, the EPS motor, 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), connect the HDS to the DLC (data link connector) (A) located under the driver's side of the dashboard.
  2. Turn the ignition switch to ON (II).
  3. Make sure the HDS communicates with the vehicle and the EPS control unit. If it does not, go to the DLC circuit troubleshoot (see «DLC CIRCUIT TROUBLESHOOTING»(ref-513153-S33429882062012110700000) ).
  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).

Torque Sensor

When the steering wheel is turned, twist occurs in the torsion bar between the steering side of the input shaft and the output shaft on the road reaction force side.

Inductance is changed by the movement of the core. The amount this voltage changes (varies with the amount of movement and direction of the core) is amplified with the interface circuitry of the sensor coil and output to the EPS control unit as a steer signal.

DTC 31-01: Torque Sensor Neutral Position Not Written

  1. Turn the ignition switch to ON (II).
  2. Clear the DTC with the HDS.
  3. Turn the ignition switch to LOCK (0).
  4. Do the memorizing of the torque sensor neutral position (see «MEMORIZING THE TORQUE SENSOR NEUTRAL POSITION»(ref-513192-S40795125382012110700000) ).
  5. Turn the ignition switch to ON (II).
  6. Check for DTCs with the HDS. Is DTC 31-01 indicated? YES -Replace the EPS control unit (see «EPS CONTROL UNIT REMOVAL/INSTALLATION»(ref-513192-S06147897662012110700000) ). NO -Intermittent failure, the system is OK at this time.
