DTC P0524:00 [PCM (SKYACTIV-G 2.5T)]

id0102s8339700

DTC P0524:00

Engine oil pressure too low

DETECTION CONDITION

•  After 10 s have elapsed since engine start (including engine-stop by i-stop control) and 3 s have elapsed since the actual engine oil pressure falls below the specified value.

Diagnostic support note

•  This is a continuous monitor (other).

•  The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle.

•  FREEZE FRAME DATA/Snapshot data is available.

•  DTC is stored in the PCM memory.

FAIL-SAFE FUNCTION

•  Restricts the upper limit of the engine speed.

•  Restricts engine load.

POSSIBLE CAUSE

•  Engine oil leakage

•  Improper engine oil level

•  Engine oil pressure sensor/engine oil temperature sensor connector or terminals malfunction

•  PCM connector or terminals malfunction

•  Engine oil pressure sensor malfunction

•  Oil pump malfunction

•  PCM malfunction

DTC P0524:00	Engine oil pressure too low
DETECTION CONDITION	• After 10 s have elapsed since engine start (including engine-stop by i-stop control) and 3 s have elapsed since the actual engine oil pressure falls below the specified value. Diagnostic support note • This is a continuous monitor (other). • The check engine light illuminates if the PCM detects the above malfunction condition during the first drive cycle. • FREEZE FRAME DATA/Snapshot data is available. • DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	• Restricts the upper limit of the engine speed. • Restricts engine load.
POSSIBLE CAUSE	• Engine oil leakage • Improper engine oil level • Engine oil pressure sensor/engine oil temperature sensor connector or terminals malfunction • PCM connector or terminals malfunction • Engine oil pressure sensor malfunction • Oil pump malfunction • PCM malfunction
SYSTEM WIRING DIAGRAM	• Not applicable

Diagnostic Procedure

STEP	INSPECTION	RESULTS	ACTION
1	RECORD VEHICLE STATUS AT TIME OF DTC DETECTION TO UTILIZE WITH REPEATABILITY VERIFICATION Note • Recording can be facilitated using the screen capture function of the PC. • Record the FREEZE FRAME DATA/snapshot data on the repair order.	—	Go to the next step.
2	VERIFY RELATED SERVICE INFORMATION AVAILABILITY • Verify related Service Information availability. • Is any related Service Information available?	Yes	Perform repair or diagnosis according to the available Service Information. • If the vehicle is not repaired, go to the next step.
2		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 part according to the inspection results, then add genuine motor oil. (See ENGINE OIL REPLACEMENT [SKYACTIV-G 2.5T].) Perform the “ENGINE OIL DATA RESET”, then go to Step 9. (See ENGINE OIL DATA RESET [SKYACTIV-G 2.5T].)
3		No	Go to the next step.
4	INSPECT ENGINE OIL LEVEL • Inspect the engine oil level. (See ENGINE OIL LEVEL INSPECTION [SKYACTIV-G 2.5T].) • Is the engine oil level sufficient?	Yes	Go to the next step.
4		No	Add genuine motor oil. (See ENGINE OIL REPLACEMENT [SKYACTIV-G 2.5T].) Perform the “ENGINE OIL DATA RESET”, then go to the next step. (See ENGINE OIL DATA RESET [SKYACTIV-G 2.5T].)
5	INSPECT ENGINE OIL PRESSURE SENSOR/ENGINE OIL TEMPERATURE SENSOR CONNECTOR CONDITION • Switch the ignition off. • Disconnect the engine oil pressure sensor/engine oil temperature sensor connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 9.
5		No	Go to the next step.
6	INSPECT PCM CONNECTOR CONDITION • Disconnect the PCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 9.
6		No	Go to the next step.
7	INSPECT ENGINE OIL PRESSURE SENSOR • Reconnect all disconnected connectors. • Inspect the engine oil pressure sensor. (See ENGINE OIL PRESSURE SENSOR INSPECTION [SKYACTIV-G 2.5T].) • Is there any malfunction?	Yes	Replace the engine oil pressure sensor/engine oil temperature sensor, then go to Step 9. (See ENGINE OIL TEMPERATURE SENSOR/ENGINE OIL PRESSURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].)
7		No	Go to the next step.
8	INSPECT ENGINE OIL PRESSURE • Inspect the engine oil pressure. (See OIL PRESSURE INSPECTION [SKYACTIV-G 2.5T].) • Is there any malfunction?	Yes	Replace the oil pump, then go to the next step. (See OIL PUMP REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].)
8		No	Go to the next step.
9	VERIFY DTC TROUBLESHOOTING COMPLETED • Always reconnect all disconnected connectors. • Clear the DTC from the PCM memory using the M-MDS. (See CLEARING DTC [PCM (SKYACTIV-G 2.5T)].) • Start the engine. • Increase and keep the engine speed at 2,500 rpm for 5 s. • Perform the DTC Reading Procedure. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-G 2.5T)].) • Is the same Pending DTC present?	Yes	Repeat the inspection from Step 1. • If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.5T].) Go to the next step.
9		No	Go to the next step.
10	VERIFY AFTER REPAIR PROCEDURE • Perform the “AFTER REPAIR PROCEDURE”. (See AFTER REPAIR PROCEDURE [PCM (SKYACTIV-G 2.5T)].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [PCM (SKYACTIV-G 2.5T)].)
10		No	DTC troubleshooting completed.
