DTC P055F:00 PCM (SKYACTIV-G 2.5 - WITH CYLINDER DEACTIVATION) DETECTION CONDITION AND POSSIBLE CAUSE

DESCRIPTION	ENGINE OIL PRESSURE MALFUNCTION
DETECTION CONDITION	Determination conditions	If any of the following conditions is met under condition A or condition B: Condition A: The actual hydraulic pressure is extremely high for a continuous 10 s even if the PCM commands low hydraulic pressure. Condition B: The actual hydraulic pressure is extremely low for a continuous 10 s even if the PCM commands low hydraulic pressure.
	Drive cycle	1
	Self test type	CMDTC self test
	Sensor used	Engine oil pressure sensor
FAIL-SAFE FUNCTION	Condition A: Not applicable. Condition B: Restricts the upper limit of the engine speed. PCM restricts engine torque.
VEHICLE STATUS WHEN DTCs ARE OUTPUT	Illuminates engine oil warning light.
POSSIBLE CAUSE	Engine oil leakage Improper engine oil level Engine oil temperature sensor/engine oil pressure sensor connector or terminals malfunction PCM connector or terminals malfunction Short to ground in wiring harness between the following terminals: Engine oil temperature sensor/engine oil pressure sensor terminal A-PCM terminal 1D Engine oil temperature sensor/engine oil pressure sensor terminal D-PCM terminal 1AS Engine oil temperature sensor/engine oil pressure sensor terminal C-PCM terminal 1AB Open circuit in wiring harness between the following terminals: Engine oil temperature sensor/engine oil pressure sensor terminal A-PCM terminal 1D Engine oil temperature sensor/engine oil pressure sensor terminal D-PCM terminal 1AS Engine oil temperature sensor/engine oil pressure sensor terminal C-PCM terminal 1AB Short to power supply in wiring harness between the following terminals: Engine oil temperature sensor/engine oil pressure sensor terminal A-PCM terminal 1D Engine oil temperature sensor/engine oil pressure sensor terminal D-PCM terminal 1AS Engine oil temperature sensor/engine oil pressure sensor terminal C-PCM terminal 1AB Engine oil temperature sensor/engine oil pressure sensor circuits are shorted to each other Engine oil pressure sensor malfunction Engine oil solenoid valve malfunction Oil pump malfunction PCM malfunction
