PGM-FI System

26. Reconnect all connectors.

27. 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).

28. 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), and wait

2 seconds.

2. Check the MAF SENSOR in the DATA LIST with the

HDS.

Go to step 3.

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.

3. Turn the ignition switch to LOCK (0).

4. Jump the SCS line with the HDS.

5. Disconnect the MAF sensor/IAT sensor 5P

connector.

6. Disconnect ECM/PCM connector B (44P).

MAF Sensor Circuit High Voltage

Is DT C P0102 indicated?

Is about 202 gm/ s, or 4.89 V or mor e indicated?

7. Check for continuity between MAF sensor/IAT

sensor 5P connector terminal No. 2 and ECM/PCM
connector terminal B32.

Go to step 8.

Repair open in the wire between the ECM/

PCM (B32) and the MAF sensor/IAT sensor, then go
to step 15.

8. Reconnect ECM/PCM connector B (44P).

9. Connect MAF sensor/IAT sensor 5P connector

terminals No. 1 and No. 2 with a jumper wire.

10. Turn the ignition switch to ON (II).

11. Clear the DTC with the HDS.

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

Go to step 20.

Go to step 13.

13. Turn the ignition switch to LOCK (0).

14. Replace the MAF sensor/IAT sensor (see page

11-224).

15. Reconnect all connectors.

16. Turn the ignition switch to ON (II).

17. Reset the ECM/PCM with the HDS.

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

11-310).

PGM-FI System

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

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. Check the MAP SENSOR in the DATA LIST with the

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).

6. Check the MAP SENSOR in the DATA LIST with the

HDS.

Go to step 12.

Go to step 7.
