1. Turn the ignition switch ON (II).

2. Check the IAT with a scan tool or the HDS.

Go to step 3.

Intermittent failure, system is OK at this time.

Check for poor connections or loose terminals at
the IAT sensor and the ECM/PCM.

3. Turn the ignition switch OFF.

4. Disconnect the IAT sensor 2P connector.

5. Connect IAT sensor 2P connector terminals No. 1

and No. 2 with a jumper wire.

6. Turn the ignition switch ON (II).

7. Check the IAT with a scan tool or the HDS.

Go to step 8.

Replace the IAT sensor (see page 11-281).

8. Turn the ignition switch OFF.

9. Remove the jumper wire.

10. Turn the ignition switch ON (II).

11. Measure voltage between IAT sensor 2P connector

terminal No. 2 and body ground.

Go to step 12.

Go to step 15.

12. Turn the ignition switch OFF.

13. Connect IAT sensor 2P connector terminal No. 1 to

body ground with a jumper wire.

14. Check for continuity between ECM/PCM connector

terminal A10 and body ground.

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).

Repair open in the wire between the ECM/

PCM (A10) and the IAT sensor.

15. Measure voltage between ECM/PCM connector

terminal B17 and body ground.

Repair open in the wire between the ECM/

PCM (B17) and the IAT 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).

5. Connect IAT sensor 2P connector terminals No. 1

and No. 2 with a jumper wire.

6. Turn the ignition switch ON (II).

7. Check the IAT SENSOR in the DATA LIST with the

HDS.

Go to step 8.

Go to step 18.

8. Turn the ignition switch OFF.

9. Remove the jumper wire from the IAT sensor 2P

connector.

10. Turn the ignition switch ON (II).

11. Measure voltage between IAT sensor 2P connector

terminal No. 2 and body ground.

Go to step 12.

Go to step 17.

12. Turn the ignition switch OFF.

13. Jump the SCS line with the HDS.

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

15. Connect IAT sensor 2P connector terminal No. 1 to

body ground with a jumper wire.

22. Reset the ECM/PCM with the HDS.

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

11-349).

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

If DTC P0113 is indicated, check for poor

connections or loose terminals at the IAT 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.

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

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

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

If DTC P0113 is indicated, check for poor

connections or loose terminals at the IAT 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.

If the ECM/PCM was updated, troubleshooting

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