## DTC Troubleshooting: 16

DTC 16: | Torque Sensor VT3 and VT6

1. | Clear the DTC.

2. | Start the engine.

3. | Wait at least 10 seconds. 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 16 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 EPS control unit connector B (14P) and the torque sensor 7P connector.

6. | Check for continuity between the appropriate EPS control unit connector B (14P) terminal and body ground (see table).
Terminal name | EPS control unit connector B terminal No.

Is there continuty? YES - Go to 11. NO - Repair open in the appropriate torque sensor wire circuit between the EPS control unit and the torque sensor.n

11. | Substitute a known-good EPS control unit, and reconnect the disconnected connectors.

12. | Start the engine. Does the EPS indicator come on? YES - Go to 13. NO - Check for loose EPS control unit connectors. If necessary, replace the EPS control unit and recheck.n

13. | Stop the engine, and verify the DTC. Is DTC 16 indicated? YES - Check for loose torque sensor connectors. If necessary, substitute a known-good steering gearbox and recheck.n NO - Perform the appropriate troubleshooting for the code indicated.n
