1. Turn the ignition switch ON (II).
2. Check the OIL PRESSURE SENSOR in the DATA LIST with the HDS. Is there about 4.79 V or more? YES - Go to step 3. NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the oil pressure sensor and the PCM.
3. Turn the ignition switch OFF.
4. Disconnect the EOP sensor 3P connector.
5. Connect EOP sensor 3P connector terminals No. 2 and No. 3 with a jumper wire.
6. Turn the ignition switch ON (II).
7. Check the OIL PRESSURE SENSOR in the DATA LIST with the HDS. Is there about 4.79 V or more? YES - Go to step 8. NO - Go to step 18 .
8. Remove the jumper wire.
9. Measure voltage between EOP sensor 3P connector terminals No. 1 and No. 3. Is there about 5 V? YES - Go to step 14 . NO - Go to step 10.
10. Turn the ignition switch OFF.
11. Jump the SCS line with the HDS.
12. Disconnect PCM connector C (44P).
13. Check for continuity between PCM connector terminal C14 and EOP sensor 3P connector terminal No. 3. Is there continuity? YES - Go to step 27 . NO - Repair open in the wire between the PCM (C14) and the EOP sensor, then go to step 20 .
14. Turn the ignition switch OFF.
15. Jump the SCS line with the HDS.
16. Disconnect PCM connector C (44P).
17. Check for continuity between PCM connector terminal C22 and EOP sensor 3P connector terminal No. 2. Is there continuity? YES - Go to step 27 . NO - Repair open in the wire between the PCM (C22) and the EOP sensor, then go to step 20.
18. Turn the ignition switch OFF.
19. Replace the EOP sensor (see «EOP SENSOR REMOVAL/INSTALLATION»(ref-243331-S18823069572006082300000) ).
20. Reconnect all connectors.
21. Turn the ignition switch ON (II).
22. Reset the PCM with the HDS.
23. Do the PCM Idle Learn Procedure (see «PCM IDLE LEARN PROCEDURE»(ref-243313-S13405059332006082300000) ).
24. Check for Temporary DTCs or DTCs with the HDS. If DTC P0523 is indicated? YES - Check for poor connections or loose terminals at the EOP sensor and the PCM, then go to step 1 . NO - Go to step 25.
25. Monitor the OBD STATUS for DTC P0523 in the DTCs MENU with the HDS. Does the screen indicated PASSED? YES - Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the indicated «DTC'S TROUBLESHOOTING»(ref-243331-S34035497822006082300000) . NO - If the screen indicates FAILED, check for poor connections or loose terminals at the EOP sensor and the PCM, then go to step 1 . If the screen indicates NOT COMPLETED, keep idling until a result comes on..
26. Reconnect all connectors.
27. Update the PCM if it does not have the latest software (see «PCM UPDATING AND SUBSTITUTION FOR TESTING»(ref-243311-S19790429062006082300000) ), or substitute a known-good PCM (see «HOW TO SUBSTITUTE THE PCM»(ref-243311-S24543735662006082300000) ).
28. Start the engine, and let it idle.
29. Check for Temporary DTCs or DTCs with the HDS. If DTC P0523 is indicated? YES - Check for poor connections or loose terminals at the EOP sensor and the PCM. If the PCM was updated, substitute a known-good PCM (see «HOW TO SUBSTITUTE THE PCM»(ref-243311-S24543735662006082300000) ), then go to step 28 . If the PCM was substituted, go to step 1 . NO - Go to step 30.
30. Monitor the OBD STATUS for DTC P0522 in the DTCs MENU with the HDS. Does the screen indicate PASSED? YES - Troubleshooting is complete. If any other Temporary DTCs or DTCs are indicated, go to the indicated «DTC'S TROUBLESHOOTING»(ref-243331-S34035497822006082300000) . NO - If the screen indicates FAILED, check for poor connections or loose terminals at the EOP sensor and the PCM. If the PCM was updated, substitute a known-good PCM (see «HOW TO SUBSTITUTE THE PCM»(ref-243311-S24543735662006082300000) ), then go to step 28 . If the PCM was substituted, go to step 1 .
