DTC P06DB-00: Engine Oil Solenoid Valve Control Circuit Low Input: Notes

DTC P06DB:00 DETECTION CONDITION AND POSSIBLE CAUSE

DTC P06DB:00	Engine oil solenoid valve control circuit low input
DETECTION CONDITION	If the PCM detects that the engine oil solenoid valve control voltage at the PCM terminal 1CK is specified value or less for 2 s with the following condition met, the PCM determines that the engine oil solenoid valve circuit voltage is low. MONITORING CONDITIONS Battery voltage: 8 V or more 0.5 s have elapsed after the ignition was switched ON (engine off or on) Engine oil solenoid valve control duty value: 94% or less 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 not 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 Short to ground or open circuit in engine oil solenoid valve power supply circuit Short to ground in wiring harness between ENGINE4 15 A fuse and engine oil solenoid valve terminal A ENGINE4 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 engine oil solenoid valve terminal B and PCM terminal 1CK PCM connector or terminals malfunction Open circuit in wiring harness between engine oil solenoid valve terminal B and PCM terminal 1CK Engine oil solenoid valve malfunction PCM malfunction
