DTC P0522: | EOP Sensor Circuit Low Voltage |
1. | Turn the ignition switch ON (II). |
2. | Check the OIL PRESSURE SENSOR in the DATA LIST with the HDS. Is there about 0.18 V or less? YES - Go to 3. NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the EOP sensor and the ECM/PCM.n |
3. | Turn the ignition switch OFF. |
4. | Disconnect the EOP sensor 3P connector. |
5. | Turn the ignition switch ON (II). |
6. | Check the OIL PRESSURE SENSOR in the DATA LIST with the HDS. Is there about 0.18 V or less? YES - Go to 8. NO - Go to 7. |
7. | Measure voltage between EOP sensor 3P connector terminals No. 1 and No. 3.
Is there about 5 V? YES - Go to 16. NO - Go to 12. |
8. | Turn the ignition switch OFF. |
9. | Jump the SCS line with the HDS. |
10. | Disconnect ECM/PCM connector C (44P). |
11. | Check for continuity between EOP sensor 3P connector terminal No. 2 and body ground.
Is there continuity? YES - Repair short in the wire between the ECM/PCM (C22) and the EOP sensor, then go to 18. NO - Go to 24. |
12. | Turn the ignition switch OFF. |
13. | Jump the SCS line with the HDS. |
14. | Disconnect ECM/PCM connector C (44P). |
15. | Check for continuity between ECM/PCM connector terminal C13 and EOP sensor 3P connector terminal No. 1.
Is there continuity? YES - Go to 24. NO - Repair open in the wire between the ECM/PCM (C13) and the EOP sensor, then go to 18. |
16. | Turn the ignition switch OFF. |
17. | Replace the EOP sensor. |
18. | Reconnect all connectors. |
19. | Turn the ignition switch ON (II). |
20. | Reset the ECM/PCM with the HDS. |
21. | Do the ECM/PCM idle learn procedure. |
22. | Check for Temporary DTCs or DTCs with the HDS. Are any Temporary DTCs or DTCs indicated? YES - If DTC P0522 is indicated, check for poor connections or loose terminals at the EOP sensor and the ECM/PCM, then go to 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting. NO - Go to 23. |
23. | Monitor the OBD STATUS for DTC P0522 in the DTCs MENU with the HDS. Does the screen indicate PASSED? YES - Troubleshooting is complete.n NO - If the screen indicates FAILED, check for poor connections or loose terminals at the EOP sensor and the ECM/PCM, then go to 1. If the screen indicates NOT COMPLETED, go to 21 and recheck. |
24. | Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM. |
25. | Check for Temporary DTCs or DTCs with the HDS. Are any Temporary DTCs or DTCs indicated? YES - If DTC P0522 is indicated, check for poor connections or loose terminals at the EOP sensor and the ECM/PCM, then go to 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.n |
