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 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.

Is there about 5 V?  

YES - Go to step 13. 

NO - Go to step 8. 

8. Measure voltage between PCM connector terminals C4 and C6.

Is there about 5 V?  

YES - Repair open in the wire between the PCM (C6) 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 PCM connector C (22P).  

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 PCM (C5) and the MAP sensor, then go to step 15. 

NO - Go to step 20. 

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 PCM with the HDS.  

18. Do the PCM idle learn procedure (see 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 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 PCM if it does not have the latest software (see UPDATING THE PCM ), or substitute a 

known-good PCM (see SUBSTITUTING THE PCM ).  

21. 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 PCM. If the PCM 
was updated, substitute a known-good PCM (see SUBSTITUTING THE PCM ), then recheck. If the 
PCM was substituted, go to step 1. 

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

DTC P0108: MAP SENSOR CIRCUIT HIGH VOLTAGE 

1. Turn the ignition switch ON (II).  

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

Is 160 kPa (47.1 in.Hg, 1,197 mmHg), or 4.49 V or more 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 PCM 

3. Turn the ignition switch OFF.  

4. Disconnect the MAP sensor 3P connector.  

5. Connect MAP sensor 3P connector terminals No. 2 and No. 3 with a jumper wire. 

NOTE:

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