Nissan Rogue Service Manual: P0524 engine oil pressure

Nissan Rogue Service Manual / Engine / Engine Control System / DTC/Circuit diagnosis / P0524 engine oil pressure

DTC Description

DTC DETECTION LOGIC

DTC No.	CONSULT screen terms (Trouble diagnosis content)	DTC detecting condition
P0524	ENGINE OIL PRESSURE (Engine oil pressure too low)	An EOP sensor signal voltage applied to ECM remains lower than the specified value continuously for 10 seconds or more when the engine speed is 1,000 rpm or more.

POSSIBLE CAUSE

Decrease in engine oil pressure
Decrease in engine oil level
Engine oil condition
EOP sensor
Engine body

FAIL-SAFE

ECM illuminates oil pressure warning lamp on the combination meter.
Engine speed will not rise more than 4,000rpm due to the fuel cut.
Fail-safe is canceled when ignition switch OFF → ON.

DTC CONFIRMATION PROCEDURE

CAUTION: If “EC-362, "Diagnosis Procedure"” is unfinished, be sure to perform Step 3 and 4.

1.PRECONDITIONING-1

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure before conducting the next test.

Turn ignition switch OFF and wait at least 10 seconds.
Turn ignition switch ON.
Turn ignition switch OFF and wait at least 10 seconds.

TEST CONDITION: Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.

>> GO TO 2.

2.PRECONDITIONING-2

Is “Diagnosis Procedure” of DTC P0524 finished? YES >> GO TO 3.

NO >> GO TO 4.

3.PERFORM DTC CONFIRMATION PROCEDURE

Start engine and warm it up to normal operating temperature.
Maintain the following conditions for about 10 consecutive seconds.

Selector lever	P or N position
Engine coolant temperature	70°C (158°F) or more
Engine speed	1,000 rpm or more

NOTE: With engine speed set around 4,000 rpm, the phenomenon can be reproduced more easily.

3. Check 1st trip DTC.

Is 1st trip DTC detected? YES >> Proceed to EC-362, "Diagnosis Procedure".

NO >> INSPECTION END

4.CHECK ENGINE OIL LEVEL

Check engine oil pressure. Refer to LU-7, "Inspection".

Is the inspection result normal? YES >> GO TO 5.

NO >> Proceed to EC-362, "Diagnosis Procedure".

5.CHECK ENGINE OIL PRESSURE

With CONSULT

Turn ignition switch ON.
Select “DATA MONITOR” mode of “ENGINE” using CONSULT.
Start the engine and check that “EOP SENSOR” changes, according to engine speeds.

Monitor item	Condition		Value (Approx.)
EOP SENSOR	Engine oil temperature: 80°C (176°F) Selector lever: P or N position Air conditioner switch: OFF No load	Engine speed: Idle	1,450 mV or more
		Engine speed: 2,000 rpm	2,850 mV or more

Without CONSULT

Check engine oil level. Refer to LU-7, "Inspection".

Is the inspection result normal? YES >> GO TO 3.

NO >> Proceed to EC-362, "Diagnosis Procedure".

Diagnosis Procedure

1.CHECK ENGINE OIL LEVEL

Turn ignition switch OFF.
Check engine oil pressure level. Refer to LU-7, "Inspection".

Is the inspection result normal? YES >> GO TO 2.

NO >> GO TO 4.

2.CHECK ENGINE OIL PRESSURE

With CONSULT

Turn ignition switch ON.
Select “DATA MONITOR” mode of “ENGINE” using CONSULT.
Start the engine and check that “EOP SENSOR” changes, according to engine speeds.

Monitor item	Condition		Value (Approx.)
EOP SENSOR	Engine oil temperature: 80°C (176°F) Selector lever: P or N position Air conditioner switch: OFF No load	Engine speed: Idl	1,450 mV or more
		Engine speed: 2,000 rpm	2,850 mV or more

Without CONSULT

Check engine oil pressure. Refer to LU-7, "Inspection".

Is the inspection result normal? YES >> GO TO 3.

NO >> Check oil pump. Refer to LU-15, "Inspection".

3.CHECK EOP SENSOR

Check EOP sensor. Refer to EC-360, "Component Inspection".

Is the inspection result normal?

YES >> GO TO 6.

NO >> Repair or replace error-detected parts.

4.CHECK ENGINE OIL LEAKAGE

Check engine oil leakage. Refer to LU-6, "Engine Lubrication System Schematic".

Is the inspection result normal? YES >> GO TO 5.

NO >> Repair or replace error-detected parts.

5.CHECK CAUSE OF ENGINE OIL CONSUMPTION

Check the following item.

Check cause of engine oil consumption

>> Repair or replace error-detected parts.

6.CHECK INTERMITTENT INCIDENT

Refer to GI-41, "Intermittent Incident".

>> INSPECTION END

Component Inspection

1.CHECK EOP SENSOR

Turn ignition switch OFF.
Disconnect EOP sensor harness connector.
Check resistance between EOP sensor connector terminals.

Check EOP sensor

Is the inspection result normal? YES >> INSPECTION END.

NO >> Replace EOP sensor. Refer to EC-14, "Component Parts Location".
