||||
|---|---|---|---|---|---|
|
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

Repair completion verification 1
|
VERIFY THAT VEHICLE IS REPAIRED
• Install/connect the part removed/disconnected during the troubleshooting procedure.
• Clear the DTC recorded in the memory. (See CLEARING DTC.)
• Replicate the vehicle conditions at the time the DTC was detected using the following procedure.
• Perform the DTC inspection for the PCM. (See DTC INSPECTION.)
• Is the same Pending DTC present?
|
Yes
|
Refer to the controller area network (CAN) malfunction diagnosis flow to inspect for a CAN communication error.
If the CAN communication is normal, perform the diagnosis from Step 1.
• If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITH CYLINDER DEACTIVATION (US))].) (See PCM REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
