DTC P0522-00: Engine Oil Pressure Sensor Circuit Low Input: Notes

DTC P0522:00 Engine oil pressure sensor circuit low input
DETECTION CONDITION 
  • If the input voltage at the PCM terminal 1AY is less than 0.16 V  for 2 s  , the PCM determines that the engine oil pressure sensor circuit is low.

    MONITORING CONDITIONS 

    • Battery voltage: 8-20 V 
    • 0.5 s  have elapsed after the ignition was switched ON (engine off or on)

      Diagnostic support note 

  • This is a continuous monitor (CCM).
  • The check engine light does not illuminate.
  • FREEZE FRAME DATA is not available.
  • Snapshot data is available.
  • DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION 
  • Restricts the upper limit of the engine speed.
  • Restricts engine load.
POSSIBLE CAUSE 
  • Engine oil pressure sensor/engine oil temperature sensor connector or terminals malfunction
  • Short to ground in wiring harness between the following terminals:
    • Engine oil pressure sensor/engine oil temperature sensor terminal A-PCM terminal 1CA
    • Engine oil pressure sensor/engine oil temperature sensor terminal D-PCM terminal 1AY
  • PCM connector or terminals malfunction
  • Engine oil pressure sensor signal circuit and ground circuit are shorted to each other
  • Open circuit in wiring harness between engine oil pressure sensor/engine oil temperature sensor terminal A and PCM terminal 1CA
  • Engine oil pressure sensor malfunction
  • PCM malfunction
