DTC Troubleshooting: 11, 13

DTC 11, 13:  Torque Sensor


1.Clear the DTC.

2.Start the engine.

Does the EPS indicator come on?


YES - Go to 3.


NO - The system is OK at this time.n


3.Stop the engine, and verify the DTC.

Is DTC 11 or 13 indicated?


YES - Go to 4.


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


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

5.Check for continuity between EPS control unit connector D (3P) terminal No. 1 and body ground.
