DTC P0522:
Rocker Arm Oil Pressure Sensor (EOP Sensor) Circuit Low Voltage
NOTE:
- Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information Initial Inspection and Diagnostic Overview.
- Information marked with an asterisk (*) applies to '07-11 models.
1. Turn the ignition switch to 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 step 3.
NO -
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the rocker arm oil pressure sensor (EOP sensor) and the ECM/PCM.�
3. Turn the ignition switch to LOCK (0).
4. Disconnect the rocker arm oil pressure sensor (EOP sensor) 3P connector.
5. Turn the ignition switch to 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 step 8.
NO -
Go to step 7.
7. Measure the voltage between rocker arm oil pressure sensor (EOP sensor) 3P connector terminals No. 1 and No. 3.
Is there about 5 V?
YES -
Go to step 16.
NO -
Go to step 12.
8. Turn the ignition switch to LOCK (0).
9. Jump the SCS line with the HDS.
10. Disconnect ECM/PCM connector C (44P).
11. Check for continuity between rocker arm oil pressure sensor (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 rocker arm oil pressure sensor (EOP sensor), then go to step 18.
NO -
Go to step 24.
12. Turn the ignition switch to LOCK (0).
13. Jump the SCS line with the HDS.
14. Disconnect ECM/PCM connector C (44P) (B (44P))*.
15. Check for continuity between ECM/PCM connector terminal C13 (B18)* and rocker arm oil pressure sensor (EOP sensor) 3P connector terminal No. 1.
'06 model
'07-11 models
Is there continuity?
YES -
Go to step 24.
NO -
Repair open in the wire between the ECM/PCM (C13) (B18)* and the rocker arm oil pressure sensor (EOP sensor), then go to step 18.
16. Turn the ignition switch to LOCK (0).
17. Replace the rocker arm oil pressure sensor (EOP sensor) Service and Repair.
18. Reconnect all connectors.
19. Turn the ignition switch to ON (II).
20. Reset the ECM/PCM with the HDS.
21. Do the ECM/PCM idle learn procedure ECM/PCM Idle Learn Procedure.
22. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0522 indicated?
YES -
Check for poor connections or loose terminals at the rocker arm oil pressure sensor (EOP sensor) and the ECM/PCM, then go to step 1.
NO -
Go to step 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. If any other Pending or Confirmed DTCs were indicated in step 22, go to the indicated DTC's troubleshooting.�
NO -
If the screen indicates FAILED, check for poor connections or loose terminals at the rocker arm oil pressure sensor (EOP sensor) and the ECM/PCM, then go to step 1. If the screen indicates NOT COMPLETED, keep idling until a result comes on.
24. Reconnect all connectors.
25. Update the ECM/PCM if it does not have the latest software ECM/PCM Update, or substitute a known-good ECM/PCM.
26. Start the engine, and let it idle.
27. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0522 indicated?
YES -
Check for poor connections or loose terminals at the rocker arm oil pressure sensor (EOP sensor) and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM, then go to step 26. If the ECM/PCM was substituted, go to step 1.
NO -
Go to step 28.
28. Monitor the OBD STATUS for DTC P0522 in the DTCs MENU with the HDS.
Does the screen indicate PASSED?
YES -
If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM Service and Repair. If any other Pending or Confirmed DTCs were indicated in step 27, go to the indicated DTC's troubleshooting.�
NO -
If the screen indicates FAILED, check for poor connections or loose terminals at the rocker arm oil pressure sensor (EOP sensor) and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM, then go to step 26. If the ECM/PCM was substituted, go to step 1. If the screen indicates NOT COMPLETED, keep idling until a result comes on.
