DTC Troubleshooting: P2652 (2.0L Engine): Inspection
Rocker Arm Oil Pressure Sensor Inspection
NOTE:
Since there is no direct method to test the component itself, troubleshooting is performed on the related components.
Test Procedure
Oil pressure inspection
- Preparation
-
- Engine oil: Pour engine oil to the specified level
- Procedure
-
- Turn the vehicle to the OFF (LOCK) mode.
- Disconnect the rocker arm oil pressure sensor 3P connector.
- Remove the rocker arm oil pressure sensor (A) from the rocker arm oil control valve (B), and attach the oil pressure hose (C), the pressure gauge adapter (D), the A/T Pressure Adapter (E), the A/T pressure test hose (F), and the A/T low pressure gauge w/panel (G) as shown, then attach the rocker arm oil pressure sensor with specified torque to the oil pressure gauge adapter.
- Reconnect the rocker arm oil pressure sensor 3P connector.
- Perform the confirmation procedure.
- Normal Conditions
-
- The oil pressure is less than 40 kPa (0.41 kgf/cm 2, 5.8 psi) while the status of VTEC solenoid valve on the HDS display is OFF.
Results
- If it is normal, there is a problem with the rocker arm oil pressure sensor.
- If it is abnormal, there is a problem with other related components.
Rocker Arm Oil Control Valve Inspection
Test Procedure
- If the other inspection item (s) indicated a normal condition, then it is determined that the remaining rocker arm oil control valve is the cause.
