DTC P06DD-00: Engine Oil Pressure Switch Control Circuit High Input: Notes

DTC P06DD:00 DETECTION CONDITION AND POSSIBLE CAUSE

DTC P06DD:00	Engine oil pressure switch control circuit high input
DETECTION CONDITION	The PCM detects that the difference between the target engine oil pressure and the actual engine oil pressure is 100 kPa {1.02 kgf/cm² , 14.5 psi} or more for 5 s when the following conditions are met. MONITORING CONDITIONS Engine oil temperature sensor: Normal Engine oil pressure sensor: Normal OCV: Normal Engine speed: 5, 500 rpm or less Engine oil temperature: -10-50°C {14-122°F} (Low engine speed during idling) Engine oil temperature: -10°C {14°F} or more (Engine speed is 1, 500-5, 500 rpm) Diagnostic support note This is an intermittent monitor (other). 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 solenoid valve connector or terminals malfunction Engine oil pressure sensor/engine oil temperature sensor connector or terminals malfunction Short to ground or open circuit in engine oil solenoid valve power supply circuit Short to ground in wiring harness between ENGINE 3 15 A fuse and engine oil solenoid valve terminal A ENGINE3 15 A fuse malfunction Open circuit in wiring harness between main relay terminal C and engine oil solenoid valve terminal A Short to ground in wiring harness between the following terminals: Engine oil solenoid valve terminal B-PCM terminal 1BM 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 Open circuit in wiring harness between the following terminals: Engine oil solenoid valve terminal B-PCM terminal 1BM Engine oil pressure sensor/engine oil temperature sensor terminal A-PCM terminal 1CA Engine oil solenoid valve malfunction Engine oil pressure sensor malfunction Oil pump malfunction PCM malfunction
