SM2565541

id0102t43397u5



Outline

System malfunction location

Engine oil pressure too low
Detection condition
• After 10 s have elapsed since engine start and 3 s have elapsed since the actual engine oil pressure falls below the specified value. *
*: With the conditions met, the engine oil warning indication is displayed/engine oil warning light turns on.
Fail-safe
• Restricts the upper limit of the engine speed.
Possible cause
• Engine oil leakage
• Improper engine oil level
• Engine oil temperature sensor/engine oil pressure sensor connector or terminals malfunction
• PCM connector or terminals malfunction
• Engine oil pressure sensor malfunction
• Oil pump malfunction
• PCM malfunction

Diagnostic Procedure

Step

Inspection

Results

Action
1
RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION
• Record the freeze frame data/snapshot data.

Note
• Recording can be facilitated using the screen capture function of the PC.
—
Go to the next step.
2
VERIFY RELATED REPAIR INFORMATION OR SERVICE INFORMATION AVAILABILITY
• Verify related Service Bulletins, on-line repair information, or Service Information availability.
• Is any related Information available?
Yes
Perform repair or diagnosis according to the available information.
• If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
INSPECT ENGINE OIL LEAKAGE
• Start the engine.
• Verify that there is no engine oil leakage in the hydraulic circuit.
• Is there any leakage?
Yes
Repair or replace the malfunctioning location, then add genuine motor oil.
(See ENGINE OIL REPLACEMENT [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
Perform the “ENGINE OIL DATA RESET” and perform the repair completion verification.
(See ENGINE OIL DATA RESET [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
No
Go to the next step.
4
INSPECT ENGINE OIL LEVEL
• Inspect the engine oil level. (See ENGINE OIL LEVEL INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
• Is the engine oil level sufficient?
Yes
Go to the next step.
No
Add genuine motor oil.
(See ENGINE OIL REPLACEMENT [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
Perform the “ENGINE OIL DATA RESET” and perform the repair completion verification.
(See ENGINE OIL DATA RESET [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
5
INSPECT ENGINE OIL TEMPERATURE SENSOR/ENGINE OIL PRESSURE SENSOR CONNECTOR FOR MALFUNCTION
• Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.)
• Are the connector and terminal normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
6
INSPECT PCM CONNECTOR FOR MALFUNCTION
• Inspect the applicable connector and terminal. (See CONNECTOR INSPECTION.)
• Are the connector and terminal normal?
Yes
Go to the next step.
No
Repair or replace the malfunctioning location and perform the repair completion verification.
7
INSPECT ENGINE OIL PRESSURE SENSOR FOR MALFUNCTION
• Inspect the applicable part. (See ENGINE OIL PRESSURE SENSOR INSPECTION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
• Is the part normal?
Yes
Replace the oil pump and perform the repair completion verification.
(See OIL PUMP REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
No
Repair or replace the malfunctioning location and perform the repair completion verification.
(See ENGINE OIL TEMPERATURE SENSOR/ENGINE OIL PRESSURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-G (WITHOUT CYLINDER DEACTIVATION (US))].)
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.
― Start the engine.
― Increase and keep the engine speed at 2,500 rpm for 5 s.
• 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.
(See CONTROLLER AREA NETWORK (CAN) MALFUNCTION DIAGNOSIS FLOW [(US)].)
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 (WITHOUT CYLINDER DEACTIVATION (US))].)
No
Go to the next step.
Repair completion verification 2
VERIFY IF OTHER DTCs DISPLAYED
• Perform the DTC inspection. (See DTC INSPECTION.)
• Are any other DTCs displayed?
Yes
Repair the malfunctioning location according to the applicable DTC troubleshooting.
No
DTC troubleshooting completed.
