Is there about 1.5 V?

YES -Go to step 20.

NO -Go to step 13.

13. Turn the ignition switch OFF.

14. Replace the MAF sensor/IAT sensor (see MAP SENSOR REPLACEMENT ).

15. Reconnect all connectors.

16. Turn the ignition switch ON (II).

17. Reset the ECM/PCM with the HDS.

18. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).

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

Is DTC P0103 indicated?

YES -Check for poor connections or loose terminals at the MAF sensor/IAT sensor and the ECM/PCM,
then go to step 1.

NO -Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the
INDICATED DTCS TROUBLESHOOTING.

20. Update the ECM/PCM if it does not have the latest software (see UPDATING THE ECM/PCM ), or

substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ).

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

Is DTC P0103 indicated?

YES -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 SUBSTITUTING THE
ECM/PCM ), then recheck. If the ECM/PCM was substituted, go to step 1.

NO -If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted,
replace the original ECM/PCM (see ECM/PCM REPLACEMENT ). If any other Temporary DTCs or
DTCs are indicated, go to the INDICATED DTCS TROUBLESHOOTING.

DTC P0107: MAP SENSOR CIRCUIT LOW VOLTAGE

1. Turn the ignition switch ON (II).

2. Check the MAP SENSOR in the DATA LIST with the HDS.

Is about 3 kPa (1.0 in.Hg, 26 mmHg), or 0.23 V or less indicated?

YES -Go to step 3.

NO -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 OFF.

4. Disconnect the MAP sensor 3P connector.

5. Turn the ignition switch ON (II).

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

Is about 3 kPa (1.0 in.Hg, 26 mmHg), or 0.23 V or less indicated?

YES -Go to step 9.

NO -Go to step 7.

7. Measure voltage between MAP sensor 3P connector terminals No. 1 and No. 3.

NOTE:

Before you troubleshoot, record all freeze data and any on-board snapshot, and
review the general troubleshooting information (see GENERAL
TROUBLESHOOTING INFORMATION ).

Is there about 5 V?

YES -Go to step 13.

NO -Go to step 8.

8. 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 (A21) and the MAP sensor, then go to step 15.

NO -Go to step 20.

9. Turn the ignition switch OFF.

10. Jump the SCS line with the HDS.

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

12. Check for continuity between MAP sensor 3P connector terminal No. 2 and body ground.

Is there continuity?

YES -Repair short in the wire between the ECM/PCM (A30) and the MAP sensor, then go to step 15.

NO -Go to step 21.

13. Turn the ignition switch OFF.

14. Replace the MAP sensor (see MAP SENSOR REPLACEMENT ).

15. Reconnect all connectors.

16. Turn the ignition switch ON (II).

17. Reset the ECM/PCM with the HDS.

18. Do the ECM/PCM idle learn procedure (see ECM/PCM IDLE LEARN PROCEDURE ).

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

Is DTC P0107 indicated?

YES -Check for poor connections or loose terminals at the MAP sensor and the ECM/PCM, then go to
step 1.

NO -Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the
INDICATED DTCS TROUBLESHOOTING.

20. Turn the ignition switch OFF.

21. Reconnect all connectors.

22. Update the ECM/PCM if it does not have the latest software (see UPDATING THE ECM/PCM ), or

substitute a known-good ECM/PCM (see SUBSTITUTING THE ECM/PCM ).

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

Is DTC P0107 indicated?
