1. Turn the ignition switch to ON (II), and wait 2 seconds.
2. Check the MAF SENSOR in the DATA LIST with the HDS. Is about 202 gm/s or 4.89 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 MAF sensor/IAT sensor and the ECM/PCM.
3. Turn the ignition switch to LOCK (0).
4. Jump the SCS line with the HDS.
5. Disconnect the MAF sensor/IAT sensor 5P connector.
6. Disconnect ECM/PCM connector C (22P).
7. Connect MAF sensor/IAT sensor 5P connector terminal No. 2 to body ground with a jumper wire.
8. Check for continuity between ECM/PCM connector terminal C21 and body ground. Is there continuity? YES -Go to step 9. NO -Repair open in the wire between the ECM/PCM (C21) and the MAF sensor/IAT sensor, then go to step 15 .
9. Reconnect ECM/PCM connector C (22P).
10. Reconnect the MAF sensor/IAT sensor 5P connector.
11. Start the engine. Hold the engine speed at 2,000 rpm without load (A/T in P or N, M/T in neutral).
12. Measure the voltage between ECM/PCM connector terminal C22 and body ground. Is there about 1.5 V? YES -Go to step 20 . NO -Go to step 13.
13. Turn the ignition switch to LOCK (0).
14. Replace the MAF sensor/IAT sensor (see «MAF SENSOR/IAT SENSOR REPLACEMENT»(ref-355245-S33598592802010012100000) ).
15. Reconnect all connectors.
16. Turn the ignition switch to 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-290807-S02808252682008072200000) ).
19. Check for Temporary DTCs or DTCs with the HDS. Is DTC P0103 indicated? YES -Check for poor connections or loose terminals at the MAF sensor/IAT 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. Update the ECM/PCM if it does not have the latest software (see «ECM/PCM UPDATE»(ref-355245-S27182940282010012100000) ), or substitute a known-good ECM/PCM (see «SUBSTITUTING THE ECM/PCM»(ref-290833-S34742010492008072200000) ).
21. Check for Temporary DTCs or DTCs with the HDS. Is DTC P0103 indicated? YES -Check for poor connections or loose terminals at the MAF sensor/IAT sensor and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM (see «SUBSTITUTING THE ECM/PCM»(ref-290833-S34742010492008072200000) ), 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-355245-S09328189752010012100000) ). If any other Temporary DTCs or DTCs are indicated, go to the indicated DTCs troubleshooting.
