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.

Is there continuity?


YES - Go to 6.


NO - Go to 9.


6.Disconnect the torque sensor 3P connector.

7.Check for continuity between the appropriate EPS control unit connector D (3P) terminal and body ground (see table).

Terminal name EPS CONTROL UNIT D CONNECTOR terminal No. 
VS1 
PVF 
VS2 

Is there continuity?


YES - Repair short to body ground in the appropriate sensor circuit between the torque sensor and the  EPS control unit.n


NO - Go to 8.


8.On the sensor side, check for continuity between torque sensor coil 3P connector terminal No. 2 and body ground.

Is there continuity?


YES - Replace the torque sensor.n


NO - 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

9.Check for continuity between the appropriate EPS control unit connector D (3P) and torque sensor 3P connector terminals (see table).

Terminal name Torque
Sensor terminal No. 
EPS control unit
terminal No. 
VS1 
PVF 
VS2 

Is there continuity?


YES - Go to 10.


NO - Repair open in the appropriate torque sensor circuit between  EPS control unit and torque sensor.n

10.On the sensor side, check for resistance between torque sensor 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 wire or poor connections at EPS control unit and tprque sensor connectors. If necessary, substitute a known-good  EPS control unit and recheck.n


NO - Replace the torque sensor.n
