DTC 14

DTC 14: Torque Sensor (Resistance)

DTC 14: Torque Sensor Initial
1. Turn the ignition switch ON (II).
2. Clear the DTC with the HDS.
3. Start the engine.
4. Turn the steering wheel fully to the left, and hold it in that position for 10 seconds or more.
5. Check for DTCs with the HDS.
Is DTC 14 indicated?
YES - Go to step 6.
NO - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the EPS control unit.

6. Turn the ignition switch OFF.
7. Disconnect the torque sensor 3P connector.
8. Disconnect EPS control unit connector D (31P).
9. Check for continuity between EPS control unit connector D (3P) terminals No. 1 and No. 2.





Is there continuity?
YES - Repair short in the wire between the EPS control unit terminals D1 and D2.
NO - Go to step 10.

10. Check for continuity between EPS control unit connector D (3P) terminals No. 2 and No. 3.





Is there continuity?
YES - Repair short in the wire between the EPS control unit terminals D2 and D3.
NO - Go to step 11.

11. Check for continuity between EPS control unit connector D (3P) terminals No. 1 and No. 3.





Is there continuity?
YES - Repair short in the wire between the EPS control unit terminals D1 and D3.
NO - Go to step 12.

12. On the sensor side, measure resistance between torque sensor 3P connector terminals No. 1 and No. 2, and No. 2 and No. 3 individually.





Is the resistance between 12 - 14 ohms (at 68° F (20° C))?
YES - The system is OK at this time. Check for poor connections or loose terminals at the torque sensor and the EPS control unit. If necessary, substitute a known-good EPS control unit and recheck.
NO - Replace the torque sensor.
