DTC P0522:00 [PCM (SKYACTIV-G)]
SM2334425
id0102t4212800
Outline
|
System malfunction location |
Engine oil pressure sensor circuit low input |
||||
|---|---|---|---|---|---|
|
Detection condition
|
• If the input voltage at the PCM terminal 1AS is less than 0.12 V for 2 s, the PCM determines that the engine oil pressure sensor circuit is low.
Precondition
• Battery voltage: 8—20 V
• 0.5 s have elapsed after the ignition was switched ON (engine off or on)
|
||||
|
Fail-safe
|
• Limits the engine torque or the upper limit of the engine speed.
|
||||
|
Possible cause
|
• Engine oil temperature sensor/engine oil pressure sensor connector or terminals malfunction
• Short to ground in any of the following engine oil pressure sensor circuits.
• PCM connector or terminals malfunction
• Short circuit in engine oil pressure sensor signal circuit and ground circuit
• Open circuit in engine oil pressure sensor power supply circuit
• Engine oil pressure sensor 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))].)
