DTC

P052012

Engine Oil Pressure Sensor/Switch "A" Circuit Short to Battery

DTC

P052014

Engine Oil Pressure Sensor/Switch "A" Circuit Short to Ground or Open

DESCRIPTION

Variable oil pump control uses the oil pressure control valve assembly, engine oil temperature sensor, oil pressure sensor and ECM to optimize the oil pressure and oil volume required by each component to reduce friction by monitoring the engine temperature and engine speed. The oil pressure sensor utilizes a semiconductor type pressure sensor that changes resistance in accordance with changes in pressure. An internal electrical signal that varies with the change in resistance is amplified and sent to the ECM as the engine oil pressure signal.

MONITOR DESCRIPTION

The ECM calculates the engine oil pressure based on the output voltage of the oil pressure sensor (oil pressure and temperature sensor). If the signal output from the oil pressure sensor is outside of the specified range, the MIL is illuminated and a DTC is stored.

CONFIRMATION DRIVING PATTERN

  1. Connect the Techstream to the DLC3.
  2. Turn the power switch on (IG).
  3. Turn the Techstream on.
  4. Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
  5. Turn the power switch off and wait for at least 30 seconds.
  6. Turn the power switch on (IG).
  7. Turn the Techstream on.
  8. Wait 10 seconds or more.
  9. Enter the following menus: Powertrain / Engine / Trouble Codes.
  10. Read the pending DTCs.

    HINT:

    • If a pending DTC is output, the system is malfunctioning.
    • If a pending DTC is not output, perform the following procedure.
  11. Enter the following menus: Powertrain / Engine / Utility / All Readiness.
  12. Input the DTC: P052012 or P052014.
  13. Check the DTC judgment result.

    Techstream Display

    Description

    NORMAL
    • DTC judgment completed
    • System normal

    ABNORMAL
    • DTC judgment completed
    • System abnormal

    INCOMPLETE
    • DTC judgment not completed
    • Perform driving pattern after confirming DTC enabling conditions

HINT:

  • If the judgment result is NORMAL, the system is normal.
  • If the judgment result is ABNORMAL, the system is malfunctioning.

NOTICE:

  • Vehicle Control History may be stored in the hybrid vehicle control ECU assembly if the engine is malfunctioning. Certain vehicle condition information is recorded when Vehicle Control History is stored. Reading the vehicle conditions recorded in both the freeze frame data and Vehicle Control History can be useful for troubleshooting.

  • If any "Engine Malfunction" Vehicle Control History item has been stored in the hybrid vehicle control ECU assembly, make sure to clear it. However, as all Vehicle Control History items are cleared simultaneously, if any Vehicle Control History items other than "Engine Malfunction" are stored, make sure to perform any troubleshooting for them before clearing Vehicle Control History.

HINT:

Read Freeze Frame Data using the Techstream. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
