DTC Troubleshooting: 14

DTC 14:  Torque Sensor (Resistance)
  
  


1.Clear the DTC.

2.Start the engine.

3.Turn the steering wheel fully to the left, and hold it in that position for 10 seconds or more.

Does the EPS indicator come on?


YES - Go to 4.


NO - The system is OK at this time.n


4.Stop the engine, and verify the DTC.

Is DTC 14 indicated?


YES - Go to 5.


NO - Perform the appropriate troubleshooting for the code indicated.n


5.Make sure the ignition switch is OFF, then disconnect the torque sensor 3P connector and EPS control unit connector D (3P).

6.Check for continuity between EPS control unit connector D (3P) terminals No. 1 and No. 2.

Is there continuity?


YES - Repair short between the BLU/RED and PNK wires in the torque sensor circuit between torque sensor and  EPS control unit.n


NO - Go to 7.

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

Is there continuity?


YES - Repair short between the WHT/GRN and BLU/RED wires in the torque sensor circuit between torque sensor and  EPS control unit.n


NO - Go to 8.


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

Is there continuity?


YES - Repair short between the WHT/GRN and PNK wires in the torque sensor circuit between torque sensor and  EPS control unit.n


NO - Go to 9.

9.On the sensor side, check for resistance between torque sensor coil 3P connector terminals No. 1 and No. 2, and between terminals No. 2 and No. 3.

Is the resistance between 12-14 W (at 20°, 68°F)?


YES - The EPS system is OK at this time. Check for loose wires or poor connections at EPS control unit and torque sensor connectors. If necessary, substitute a known-good  EPS control unit and recheck.n


NO - Replace the torque sensor.n
