  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 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 12 . 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 16 . NO - Go to step 8.
  8. Turn the ignition switch OFF.
  9. Jump the SCS line with the HDS.
  10. Disconnect PCM connector B (44P).
  11. Check for continuity between PCM connector terminal B18 and MAP sensor 3P connector terminal No. 1. Is there continuity? YES - Go to step 23 . NO - Repair open in the wire between the PCM (B18) and the MAP sensor, then go to step 18 .
  12. Turn the ignition switch OFF.
  13. Jump the SCS line with the HDS.
  14. Disconnect PCM connector B (44P).
  15. 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 (B30) and the MAP sensor, then go to step 18 . NO - Go to step 23 .
  16. Turn the ignition switch OFF.
  17. Replace the MAP sensor (see «MAP SENSOR REPLACEMENT»(ref-299652-S41978263672008092500000) ).
  18. Reconnect all connectors.
  19. Turn the ignition switch ON (II).
  20. Reset the PCM with the HDS.
  21. Do the PCM idle learn procedure (see «PCM IDLE LEARN PROCEDURE»(ref-219960-S21279730262006021600000) ).
  22. 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.
  23. Reconnect all connectors.
  24. Update the PCM if it does not have the latest software (see «PCM UPDATING AND SUBSTITUTION FOR TESTING»(ref-219956-S29187290912006021600000) ), or substitute a known-good PCM (see «SUBSTITUTING THE PCM»(ref-219956-S20631232652006021600000) ).
  25. 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»(ref-219956-S20631232652006021600000) ), 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»(ref-299652-S28764766372008092500000) ). If any other Temporary DTCs or DTCs are indicated, go to the indicated DTCs troubleshooting.
