19. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the MAF sensor/IAT sensor and the
ECM/PCM, then go to step 1.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.
20. Turn the ignition switch to LOCK (0).
21. Reconnect all connectors.
22. Update the ECM/PCM if it does not have the latest software (see page 11-227), or substitute a known-
good ECM/PCM (see page 11-7).
23. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the MAF sensor/IAT sensor and the
ECM/PCM. If the ECM/PCM was updated, substitute
a known-good ECM/PCM (see page 11-7), then
recheck. If the ECM/PCM was substituted, go to
step 1.
If the ECM/PCM was updated, troubleshooting
is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see page 11-228). If
any other Temporary DTCs or DTCs are indicated,
go to the indicated DTC’s troubleshooting. NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
1. Turn the ignition switch to ON (II).
2. ChecktheMAPSENSORintheDATALISTwiththe HDS.
Go to step 3.
Intermittent failure, the system is OK at this
time. Check for poor connections or loose terminals
at the MAP sensor and the ECM/PCM.
3. Turn the ignition switch to LOCK (0).
4. Disconnect the MAP sensor 3P connector.
5. Turn the ignition switch to ON (II).

IAT Sensor Circuit Range/
Performance Problem
NOTE: Before you troubleshoot, record all freeze data
and any on-board snapshot, and review the general
troubleshooting information (see page 11-3).
1. Check for poor connections or loose terminals at ECT sensor 1, ECT sensor 2, and the IAT sensor.
Go to step 2.
Repair the connections or the terminals, then
go to step 15.
2. Remove the MAF sensor/IAT sensor (see page 11-224).
3. Allow the IAT sensor to cool to ambient temperature.
4. Note the ambient temperature.
5. Connect the MAF sensor/IAT sensor to its 5P connector, but do not install the sensor onto the air
cleaner.
6. Turn the ignition switch to ON (II).
7. Note the value of the IAT SENSOR quickly in the DATA LIST with the HDS.
8. Compare the value of IAT SENSOR and the ambient temperature.
Go to step 13.
Go to step 9.
9. Disconnect the MAF sensor/IAT sensor from its 5P connector.
10. Using a heat gun, blow hot air on the MAF sensor/ IAT sensor for a few seconds. Do not apply the heat
longer than a few seconds or you will damage the
sensor. 11. Connect the MAF sensor/IAT sensor to its 5P
connector, but do not install the sensor onto the air
cleaner.
12. ChecktheIATSENSORintheDATALISTwiththe HDS.
Intermittent failure, the system is OK at this
time. Check for poor connections or loose terminals
at the MAF sensor/IAT sensor and the ECM/PCM.
Go to step 13.
13. Turn the ignition switch to LOCK (0).
14. Replace the MAF sensor/IAT sensor (see page 11-224).
15. Turn the ignition switch to ON (II).
16. Reset the ECM/PCM with the HDS.
17. Do the ECM/PCM idle learn procedure (see page 11-310).
18. Check for Temporary DTCs or DTCs with the HDS.
Check for poor connections or loose
terminals at the MAF sensor/IAT sensor and the
ECM/PCM, then go to step 1.
Troubleshooting is complete. If any other
Temporary DTCs or DTCs are indicated, go to the
indicated DTC’s troubleshooting.
