1. Reset the ECM/PCM (see page 11-4).

2. Turn the ignition switch ON (II).

Go to step 3.

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. Measure voltage between IMT (IMRC) valve

position sensor 3P connector terminals No. 1 and
No. 3.

Go to step 7.

Go to step 15.

7. Turn the ignition switch OFF.

8. At the sensor side, measure resistance between

IMT (IMRC) valve position sensor 3P connector
terminals No. 2 and No. 3.

Go to step 9.

Go to step 16.

9. Measure resistance between IMT (IMRC) valve

position sensor 3P connector terminals No. 1 and
No. 2.

Go to step 10.

Go to step 16.

10. Jump the SCS line with the HDS.

11. Disconnect ECM/PCM connector A (31P).

12. At the wire harness side, check for continuity

between IMT (IMRC) valve position sensor 3P
connector terminal No. 2 and body ground.

Repair short in the wire between the ECM/

PCM (B22) and the IMT (IMRC) valve position
sensor, then go to step 17.

Go to step 13.

13. Connect ECM/PCM connector terminal B22 to body

ground with a jumper wire.

14. At the wire harness side, check for continuity

between IMT (IMRC) valve position sensor 3P
connector terminal No. 2 and body ground.

Go to step 22.

Repair open in the wire between the ECM/

PCM (B22) and the IMT (IMRC) valve position
sensor, then go to step 17.

15. Measure voltage between ECM/PCM connector

terminals A21 and A24.

Repair open in the wire between the ECM/

PCM (A21) and the IMT (IMRC) valve position
sensor, then go to step 17.

Go to step 22.

DTC Troubleshooting (cont’d)

16. Replace the IMT (IMRC) valve position sensor

(see page 11-413).

17. Reconnect all connectors.

18. Turn the ignition switch ON (II).

19. Reset the ECM/PCM with the HDS.

20. Do the ECM/PCM idle learn procedure (see page

11-349).

21. Check for Temporary DTCs or DTCs with the HDS.

If DTC P0661 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.

Troubleshooting is complete.

22. Update the ECM/PCM if it does not have the latest

software, or substitute a known-good ECM/PCM
(see page 11-6).

23. Check for Temporary DTCs or DTCs with the HDS.

If DTC P0661 is indicated, check for poor

If the ECM/PCM was updated, troubleshooting

is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see page 11-284).

Ar e any T empor ar y DT Cs or DT Cs indicated?

1. Reset the ECM/PCM (see page 11-4).

2. Turn the ignition switch ON (II).

Go to step 3.

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.

Replace the IMT (IMRC) valve position

sensor (see page 11-413).

Go to step 7.

7. Measure voltage between ECM/PCM connector

terminals A11 and A21.

Repair open in the wire between the ECM/

PCM (A11) and the IMT (IMRC) valve position
sensor.

Update the ECM/PCM if it does not have the

latest software, or substitute a known-good ECM/
PCM (see page 11-6), then recheck. If the symptom/
indication goes away with a known-good ECM/PCM,
replace the original ECM/PCM (see page 11-284).
