DTC P0524:00 [PCM (SKYACTIV-D 2.2)]

id0102j5339700

DTC P0524:00	Engine oil pressure too low
DETECTION CONDITION	•  The engine oil pressure is less than 30 kPa for a continuous 3 s after the specified time has elapsed since the engine was started. Diagnostic support note •  This is a continuous monitor (CCM). •  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	•  Limits the engine torque/limits the maximum engine speed. •  Restricts the upper limit of the APP sensor output. •  Inhibits the automatic diesel particulate filter regeneration control. •  Inhibits the manual diesel particulate filter regeneration control. •  Inhibits the EGR control. •  Inhibits engine-stop by i-stop control.
POSSIBLE CAUSE	•  Engine oil leakage •  Insufficient engine oil •  Engine oil temperature/engine oil pressure sensor connector or terminal malfunction •  Short to ground in wiring harness between the following terminals: ―  Engine oil temperature/engine oil pressure sensor terminal A and PCM terminal 1DN ―  Engine oil temperature/engine oil pressure sensor terminal D and PCM terminal 1DM •  PCM connector or terminal malfunction •  Open circuit in wiring harness between engine oil temperature/engine oil pressure sensor terminal A and PCM terminal 1DN •  Engine oil pressure sensor malfunction •  Oil pump malfunction •  Oil strainer clogging •  PCM malfunction

Diagnostic Procedure

Step	Inspection	Results	Action
1	RECORD VEHICLE STATUS WHEN DTC WAS DETECTED TO UTILIZE WITH REPEATABILITY VERIFICATION Note •  Recording can be facilitated using the screen capture function of the PC. •  Record the freeze frame data/snap shot data.	—	Go to the next step.
2	VERIFY OTHER RELATED DTCs •  Switch the ignition OFF, and then switch it ON (engine off). •  Display the DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)].) •  Has any DTC other than P0524:00 been stored?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-D 2.2)].)
		No	Go to the next step.
3	VERIFY THAT THERE IS NO ENGINE OIL LEAKAGE •  Start the engine and verify that there is no engine oil leakage in the hydraulic circuit. •  Is there oil leakage from the oil passage?	Yes	Repair or replace the malfunctioning location and add genuine engine oil. Go to Step 11.
		No	Go to the next step.
4	INSPECT ENGINE OIL LEVEL •  Inspect the engine oil level. (See ENGINE OIL LEVEL INSPECTION [SKYACTIV-D 2.2].) •  Is the engine oil level sufficient?	Yes	Go to the next step.
		No	Add genuine engine oil, then go to the next step.
5	INSPECT ENGINE OIL TEMPERATURE/ENGINE OIL PRESSURE SENSOR CONNECTOR CONDITION •  Switch the ignition OFF. •  Disconnect the engine oil temperature/engine oil pressure sensor connector. •  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection. •  Is the connector normal?	Yes	Go to the next step.
		No	Repair or replace the connector, then go to Step 11.
6	INSPECT PCM CONNECTOR CONDITION •  Disconnect the PCM connector. •  Inspect the connector engagement and connection condition, and inspect the terminals for damage, deformation, corrosion, or disconnection. •  Is the connector normal?	Yes	Go to the next step.
		No	Repair or replace the connector, then go to Step 11.
7	INSPECT ENGINE OIL PRESSURE SENSOR CIRCUIT FOR SHORT TO GROUND •  Verify that the engine oil temperature/engine oil pressure sensor connector is disconnected. •  Inspect for continuity between the following terminals (vehicle wiring harness side) and ground. ―  Engine oil temperature sensor/engine oil pressure sensor terminal A ―  Engine oil temperature sensor/engine oil pressure sensor terminal D •  Is there continuity?	Yes	Refer to the wiring diagram and verify if there is a common connector between the following terminals. •  Engine oil temperature/engine oil pressure sensor terminal A and PCM terminal 1DN •  Engine oil temperature/engine oil pressure sensor terminal D and PCM terminal 1DM If there is a common connector: ―  Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for short to ground to determine the malfunctioning location. ―  Repair or replace the malfunctioning location. If there is no common connector: ―  Repair or replace the wiring harness which is shorted to ground. Go to Step 11.
		No	Go to the next step.
8	INSPECT ENGINE OIL PRESSURE SENSOR POWER SUPPLY CIRCUIT FOR OPEN CIRCUIT •  Verify that the engine oil temperature/engine oil pressure sensor connector and the PCM connector are disconnected. •  Inspect the wiring harness for continuity between engine oil temperature/engine oil pressure sensor terminal A (vehicle wiring harness side) and PCM terminal 1DN (vehicle wiring harness side). •  Is there continuity?	Yes	Go to the next step.
		No	Refer to the wiring diagram and verify if there is a common connector between engine oil temperature/engine oil pressure sensor terminal A and PCM terminal 1DN. If there is a common connector: •  Inspect the common connector and terminals for corrosion, damage, or disconnection and the common wiring harnesses for an open circuit to determine the malfunctioning location. •  Repair or replace the malfunctioning location. If there is no common connector: •  Repair or replace the wiring harness which has an open circuit. Go to Step 11.
9	INSPECT ENGINE OIL PRESSURE SENSOR •  Reconnect all the disconnected connectors. •  Inspect the engine oil pressure sensor. (See ENGINE OIL PRESSURE SENSOR INSPECTION [SKYACTIV-D 2.2].) •  Is the engine oil pressure sensor normal?	Yes	Go to the next step.
		No	Replace the engine oil temperature/engine oil pressure sensor, then go to Step 11. (See ENGINE OIL TEMPERATURE SENSOR/ENGINE OIL PRESSURE SENSOR REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
10	INSPECT OIL STRAINER •  Inspect the oil strainer for clogging. (See OIL PUMP REMOVAL/INSTALLATION [SKYACTIV-D 2.2].) •  Is the oil strainer normal?	Yes	Replace the oil pump, then go to the next step. (See OIL PUMP REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
		No	Replace the oil strainer, then go to the next step. (See OIL PUMP REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
11	VERIFY THAT REPAIRS HAVE BEEN COMPLETED •  Reconnect all disconnected connectors and hoses. •  Refer to the [MEMORY CLEARING PROCEDURE] and clear the DTC. (See CLEARING DTC [PCM (SKYACTIV-D 2.2)].) •  Start the engine and drive the vehicle under the freeze frame data/snapshot data condition. Warning •  To prevent an accident, work with another person when the vehicle is being driven (one person drives vehicle, other person operates M-MDS). •  Observe legal speed limits when driving the vehicle and perform the procedure in a location where safety can be assured. •  Display the DTCs using the M-MDS. (See ON-BOARD DIAGNOSTIC TEST [PCM (SKYACTIV-D 2.2)].) •  Has DTC P0524:00 been recorded?	Yes	Repeat the inspection from Step 1. •  If the malfunction recurs, replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [SKYACTIV-D 2.2].)
		No	Go to the next step.
12	VERIFY OTHER DTCs •  Has any other DTC or pending code been stored?	Yes	Repair the malfunctioning location according to the applicable DTC troubleshooting. (See DTC TABLE [PCM (SKYACTIV-D 2.2)].)
		No	DTC troubleshooting completed.
