1. Turn the ignition switch to ON (II).
2. Check the MAP SENSOR in the DATA LIST with the HDS. Is about 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 ECM.
3. Turn the ignition switch to LOCK (0).
4. Disconnect the MAP sensor 3P connector.
5. Connect the MAP sensor 3P connector terminals No. 2 and No. 3 with a jumper wire.
6. Turn the ignition switch to ON (II).
7. Check the MAP SENSOR in the DATA LIST with the HDS. Is about 160 kPa (47.1 in.Hg, 1,197 mmHg), or 4.49 V or more indicated? YES -Go to step 8. NO -Go to step 19 .
8. Remove the jumper wire from the MAP sensor 3P connector.
9. Measure the voltage between MAP sensor 3P connector terminals No. 1 and No. 3. Is there about 5 V? YES -Go to step 15 . NO -Go to step 10.
10. Turn the ignition switch to LOCK (0).
11. Jump the SCS line with the HDS.
12. Disconnect ECM connector A (31P).
13. Connect MAP sensor 3P connector terminal No. 3 to body ground with a jumper wire.
14. Check for continuity between ECM connector terminal A24 and body ground. Is there continuity? YES -Go to step 27 . NO -Repair open in the wire between the ECM (A24) and the MAP sensor, then go to step 21 .
15. Turn the ignition switch to LOCK (0).
16. Connect ECM connector terminals A24 and A30 with a jumper wire.
17. Turn the ignition switch to ON (II).
18. Check the MAP SENSOR in the DATA LIST with the HDS. Is about 160 kPa (47.1 in.Hg, 1,197 mmHg), or 4.49 V or more indicated? YES -Go to step 26 . NO -Repair open in the wire between the ECM (A30) and the MAP sensor, then go to step 21 .
19. Turn the ignition switch to LOCK (0).
20. Replace the MAP sensor (see «MAP SENSOR REPLACEMENT»(ref-351945-S30504107262009122900000) ).
21. Reconnect all connectors.
22. Turn the ignition switch to ON (II).
23. Reset the ECM with the HDS.
24. Do the ECM idle learn procedure (see «ECM IDLE LEARN PROCEDURE»(ref-221342-S09897997502006022400000) ).
25. Check for Temporary DTCs or DTCs with HDS. Is DTC P0108 indicated? YES -Check for poor connections or loose terminals at the MAP sensor and the ECM, then go to step 1 . NO -Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.
26. Turn the ignition switch to LOCK (0).
27. Reconnect all connectors.
28. Update the ECM if it does not have the latest software (see «ECM UPDATE»(ref-351945-S31385529132009122900000) ), or substitute a known-good ECM (see «SUBSTITUTING THE ECM»(ref-221338-S28616532062006022400000) ).
29. Check for Temporary DTCs or DTCs with the HDS. Is DTC P0108 indicated? YES -Check for poor connections or loose terminals at the MAP sensor and the ECM. If the ECM was updated, substitute a known-good ECM (see «SUBSTITUTING THE ECM»(ref-221338-S28616532062006022400000) ), then recheck. If the ECM was substituted, go to step 1 . NO -If the ECM was updated, troubleshooting is complete. If the ECM was substituted, replace the original ECM (see «ECM REPLACEMENT»(ref-351945-S35124653042009122900000) ). If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.
