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

DTC P0522:00 PCM (SKYACTIV-G 2.5 - WITH CYLINDER DEACTIVATION) DETECTION CONDITION AND POSSIBLE CAUSE

DTC P0522:00	Engine Oil Pressure Sensor Circuit Low Input
DETECTION CONDITION	If the input voltage at the PCM terminal 1AS 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 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 PCM 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 1D Engine oil pressure sensor/engine oil temperature sensor terminal D-PCM terminal 1AS 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 1D Engine oil pressure sensor malfunction PCM malfunction
