DTC Troubleshooting: 11, 13

DTC 11, 13: Torque Sensor

1. Turn the ignition switch ON (II).

1. Clear the DTC with the HDS.

1. Start the engine.

Does the EPS indicator come on?

YES | - | Go to Step 4 .
NO | - | The system is OK at this time.■

1. Stop the engine, and verify the DTC.

Is DTC 11 or 13 indicated?

YES | - | Go to Step 5 .
NO | - | Perform the appropriate troubleshooting for the code indicated.■

1. Turn the ignition switch OFF, then disconnect EPS control unit connector D (3P).

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

Is there continuity?

YES | - | Go to Step 7 .
NO | - | Go to Step 10 .

1. Disconnect the torque sensor 3P connector.

1. 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 | 1
   PVF | 2
   VS2 | 3

Is there continuity?

YES | - | Repair short to body ground in the appropriate wire between the torque sensor and the EPS control unit.■
NO | - | Go to Step 9 .

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

Is there continuity?

YES | - | Replace the torque sensor. ■
NO | - | The system is OK at this time. Check for loose terminals and poor connections at EPS control unit and torque sensor. If necessary, substitute a known-good EPS control unit and recheck.■

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

   Terminal name | Torque Sensor terminal No. | EPS control unit D terminal No.
   --- | --- | ---
   VS1 | 1 | 1
   PVF | 2 | 2
   VS2 | 3 | 3

Is there continuity?

YES | - | Go to Step 11 .
NO | - | Repair open in the wire between the appropriate torque sensor and EPS control unit.■

1. On the sensor side, measure 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 Ω (at 20 °C (68 °F))?

YES | - | The system is OK at this time. Check for loose terminals and poor connections at EPS control unit and torque sensor. If necessary, substitute a known-good EPS control unit and recheck.■
NO | - | Replace the torque sensor. ■
