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

DTC P06DB:00 (PCM, SKYACTIV-G) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location	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. Precondition 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
Fail-safe	Restricts the upper limit of the engine speed. Restricts engine load.
Possible cause	Engine oil solenoid valve connector or terminals malfunction F12 15 A fuse malfunction Short to ground in engine oil solenoid valve power supply circuit Open circuit in engine oil solenoid valve power supply circuit Short to ground in engine oil solenoid valve control circuit PCM connector or terminals malfunction Open circuit in engine oil solenoid valve control circuit Engine oil solenoid valve malfunction PCM malfunction
