  1. Turn the ignition switch ON (II).
  2. Clear the DTC with the HDS.
  3. Turn the ignition switch OFF.
  4. Turn the ignition switch ON (II).
  5. Check for Temporary DTCs or DTCs with the HDS. Are DTC P0107, P0122, and P0452 indicated at the same time? YES- Go to step 17 . NO- Go to step 6 .
  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 7 . NO- Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the MAP sensor and the ECM/PCM.
  7. Turn the ignition switch OFF.
  8. Disconnect the MAP sensor 3P connector.
  9. Turn the ignition switch ON (II).
  10. 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 13 . NO- Go to step 11 .
  11. Measure voltage between MAP sensor 3P connector terminals No. 1 and No. 3. Is there about 5 V? YES- Go to step 26 . NO- Go to step 12 .
  12. 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 28 . NO- Go to step 33 .
  13. Turn the ignition switch OFF.
  14. Jump the SCS line with the HDS.
  15. Disconnect ECM/PCM connector A (31P).
  16. 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 28 . NO- Go to step 33 .
  17. Turn the ignition switch OFF.
  18. Jump the SCS line with the HDS.
  19. Disconnect ECM/PCM connectors A (31P) and E (31P).
  20. Disconnect the connectors from these sensors: MAP sensor TP sensor FTP sensor Input shaft (mainshaft) speed sensor Output shaft (countershaft) speed sensor
  21. Check for continuity between body ground and ECM/PCM connector terminals A20, A21, and E5 individually. Is there continuity? YES- Repair short in the wire between the ECM/PCM (A20, A21, or E5) and each sensor, then go to step 28 . NO- Go to step 22 .
  22. Reconnect ECM/PCM connectors A (31P) and E (31P).
  23. Turn the ignition switch ON (II).
  24. Measure voltage between ECM/PCM connector terminal A21 and body ground. Is there about 5 V? YES- Go to step 25 . NO- Go to step 33 .
  25. Continue to monitor voltage at ECM/PCM connector terminal A21 while reconnecting the following sensors, one at a time. MAP sensor TP sensor FTP sensor Input shaft (mainshaft) speed sensor Output shaft (countershaft) speed sensor Did the voltage drop to about 0 V? YES- Replace the sensor that caused the voltage to drop, then go to step 30 . NO- Go to step 33 .
  26. Turn the ignition switch OFF.
  27. Replace the MAP sensor (see «MAP SENSOR REPLACEMENT»(ref-220570-S17955277902006022000000) ).
  28. Reconnect all connectors.
  29. Turn the ignition switch ON (II).
  30. Reset the ECM/PCM with the HDS.
  31. Do the ECM/PCM idle learn procedure (see «ECM/PCM IDLE LEARN PROCEDURE»(ref-220572-S08440202922006022000000) ).
  32. Check for Temporary DTCs or DTCs with the HDS. Are any Temporary DTCs or DTCs indicated? YES- If DTC P0107 is indicated, check for poor connections or loose terminals at the MAP sensor and the ECM/PCM, then go to step 1 . If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting. NO- Troubleshooting is complete.
  33. Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM (see «ECM/PCM UPDATING AND SUBSTITUTION FOR TESTING»(ref-220569-S23624043112006022000000) ).
  34. Check for Temporary DTCs or DTCs with the HDS. Are any Temporary DTCs or DTCs indicated? YES- If DTC P0107 is indicated, check for poor connections or loose terminals at the MAP sensor and the ECM/PCM, then go to step 1 . If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting. NO- If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM (see «MAP SENSOR REPLACEMENT»(ref-220570-S17955277902006022000000) ).
