P0662

DTC P0662: IMT (IMRC) Valve Position Sensor Circuit High Voltage (2005-2006 models)

1. Reset the ECM/PCM.
2. Turn the ignition switch ON (II).

Is DTC P0662 indicated?

YES - Go to step 3.

NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the IMT (IMRC) valve position sensor and the ECM/PCM.

3. Turn the ignition switch OFF.
4. Disconnect the IMT (IMRC) valve position sensor 3P connector.
5. Turn the ignition switch ON (II).




6. At the wire harness side, measure voltage between IMT (IMRC) valve position sensor 3P connector terminals No. 1 and No. 3.

Is there about 5 V?

YES - Go to step 8.

NO - Go to step 7.




7. Measure voltage between ECM/PCM connector terminals A21 and A24.

Is there about 5 V?

YES - Repair open in the wire between the ECM/PCM (A24) and the IMT (IMRC) valve position sensor, then go to step 10.

NO - Go to step 15.

8. Turn the ignition switch OFF.
9. Replace the IMT (IMRC) valve position sensor.
10. Reconnect all connectors.
11. Turn the ignition switch ON (II).
12. Reset the ECM/PCM with the HDS.
13. Do the ECM/PCM idle learn procedure.
14. Check for Temporary DTCs or DTCs with the HDS.

Are any Temporary DTCs or DTCs indicated?

YES - If DTC P0662 is indicated, check for poor connections or loose terminals at the IMT (IMRC) valve position sensor and the ECM/PCM, then go to step 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.

NO - Troubleshooting is complete.

15. Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM.
16. Check for Temporary DTCs or DTCs with the HDS.

Are any Temporary DTCs or DTCs indicated?

YES - If DTC P0662 is indicated, check for poor connections or loose terminals at the IMT (IMRC) valve position sensor and the ECM/PCM, then go to step 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.

NO - If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM.
