| P0522 Rocker Arm Oil Pressure Sensor Circuit Low Voltage |
DTC (PGM-FI)
- Problem verification
- 1. Turn the vehicle to the ON mode.
- 2. Check the parameter(s) below with the HDS.
Signal Threshold Current conditions Values Unit Values Unit ROCKER ARM OIL PRESSURE SENSOR Less than 0.18 V Do the current condition(s) match the threshold?
YES
The failure is duplicated. Go to step 2.
NO
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the rocker arm oil pressure sensor and the PCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot - Refer to: How to Troubleshoot the Fuel and Emissions Systems .
- Determine possible failure area (OP SENSOR line, others)
- 1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Disconnect the following connector.
Rocker arm oil pressure sensor 3P connector - 3. Turn the vehicle to the ON mode.
- 4. Check the parameter(s) below with the HDS.
Signal Threshold Current conditions Values Unit Values Unit ROCKER ARM OIL PRESSURE SENSOR Less than 0.18 V Do the current condition(s) match the threshold?
YES
Go to step 5.
NO
Go to step 3.
- Determine possible failure area (rocker arm oil pressure sensor, VCC2 line)
- 1. Measure the voltage between test points 1 and 2.
Test condition
Vehicle ON mode Rocker arm oil pressure sensor 3P connector: disconnected Test point 1 Rocker arm oil pressure sensor 3P connector No. 1 Test point 2 Rocker arm oil pressure sensor 3P connector No. 3 Is there about 5.0 V?
YES
Replace the rocker arm oil pressure sensor .
NO
Go to step 4.
- Open wire check (VCC2 line)
- 1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Jump the SCS line with the HDS, and wait more than 1 minute.
- 3. Disconnect the following connector.
PCM connector B (51P) - 4. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode Rocker arm oil pressure sensor 3P connector: disconnected PCM connector B (51P): disconnected Test point 1 Rocker arm oil pressure sensor 3P connector No. 3 Test point 2 PCM connector B (51P) No. 43 - Refer to:
PCM Connector for Inputs and Outputs(6-Speed A/T) (2016 2017 2018 2019 2020), or
PCM Connector for Inputs and Outputs (9-Speed A/T) (2016 2017 2018)Is there continuity?
YES
The VCC2 wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting or substitute a known-good PCM - Refer to: PCM Removal and Installation (6-Speed A/T), ('16-'18 9-Speed A/T) .
NO
Repair an open in the VCC2 wire between the PCM (B43) and the rocker arm oil pressure sensor.
- Shorted wire check (OP SENSOR line)
- 1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Jump the SCS line with the HDS, and wait more than 1 minute.
- 3. Disconnect the following connector.
PCM connector B (51P) - 4. Check for continuity between test points 1 and 2.
Test condition Vehicle OFF (LOCK) mode Rocker arm oil pressure sensor 3P connector: disconnected PCM connector B (51P): disconnected Test point 1 Rocker arm oil pressure sensor 3P connector No. 2 Test point 2 Body ground Is there continuity?
YES
Repair a short in the OP SENSOR wire between the PCM (B47) and the rocker arm oil pressure sensor.
NO
The OP SENSOR wire is OK. Check for any authorized service information related to the DTCs or symptoms you are troubleshooting or substitute a known-good PCM - Refer to: PCM Removal and Installation (6-Speed A/T), ('16-'18 9-Speed A/T) .
