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. 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»(ref-291411-S29101893712008072800000) ).
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»(ref-291413-S23447131872008072800000) ).
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»(ref-291410-S41633658632008072800000) ), or substitute a known-good ECM/PCM (see «SUBSTITUTING THE ECM/PCM»(ref-291410-S09944723422008072800000) ).
23. 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. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see «SUBSTITUTING THE ECM/PCM»(ref-291410-S09944723422008072800000) ), 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»(ref-291411-S17209936142008072800000) ). If any other Temporary DTCs or DTCs are indicated, go to the indicated DTCs troubleshooting.
