  1. Turn the ignition switch to ON (II).
  2. Check the MAP SENSOR in the DATA LIST with the HAS. Is about 3 kPa (1.0 inHg, 26 mmHg), or 0.23 V Or less Indicated? YES -Go to next step. 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 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 HAS. Is about 3 kPa (1.0 inHg, 26 mmHg), or 0.23 V or less Indicated? YES -Go to step 12 . NO -Go to next step.
  7. Measure the 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 next step.
  8. Turn the ignition switch to LOCK (0).
  9. Jump the SCS line with the HAS.
  10. Disconnect PCM connector B (49P).
  11. Check for continuity between PCM connector terminal B36 and MAP sensor 3P connector terminal No. 3. Is there continuity? YES -Go to step 23 . NO -Repair an open in the wire between the PCM (B36) and the MAP sensor, then go to step 18 .
  12. Turn the ignition switch to LOCK (0).
  13. Jump the SCS line with the HAS.
  14. Disconnect PCM connector B (49P).
  15. Check for continuity between MAP sensor 3P connector terminal No. 2 and body ground. Is there continuity? YES -Repair a short in the wire between the PCM (B35) and the MAP sensor, then go to step 18 . NO -Go to step 23 .
  16. Turn the ignition switch to LOCK (0).
  17. Replace the MAP sensor (see «MAP SENSOR REPLACEMENT»(ref-360080-S11024392292010042600000) (+).
  18. Reconnect all connectors.
  19. Turn the ignition switch to ON (II).
  20. Reset the PCM with the HAS.
  21. Do the PCM idle learn procedure (see «PCM IDLE LEARN PROCEDURE»(ref-360079-S22847966492010042600000) (+).
  22. Check for Pending or Confirmed DTCs with the HAS. 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 Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.
  23. Reconnect all connectors.
  24. Update the PCM if it does not have the latest software (see «PCM UPDATE»(ref-360080-S11980508702010042600000) (+) or substitute a known-good PCM (see «SUBSTITUTING THE PCM»(ref-360056-S32194616542010042600000) (+).
  25. Check for Pending or Confirmed DTCs with the HAS. 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-360056-S32194616542010042600000) (+) 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-360080-S27881728262010042600000) (+). If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.
