P0524 ENGINE OIL PRESSURE

DTC Description

INFOID:0000000010702981

DTC DETECTION LOGIC

POSSIBLE CAUSE

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

FAIL-SAFE

DTC CONFIRMATION PROCEDURE

CAUTION:

If 

ECM-293, "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.
1.

Turn ignition switch OFF and wait at least 10 seconds.

2.

Turn ignition switch ON.

3.

Turn ignition switch OFF and wait at least 10 seconds.

TEST CONDITION:
Before performing the following procedure, confirm that battery voltage is 10 V or more at idle.

>> GO TO 2.

2.

PRECONDITIONING-2

Is “Diagnosis Procedure” of DTC P0524 finished?

YES

>> GO TO 5.

NO

>> GO TO 3.

3.

DTC No.

CONSULT screen terms

(Trouble diagnosis content)

DTC detecting condition

P0524

ENGINE OIL PRESSURE
(Engine oil pressure too low)

ECM detects that 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.

Engine operating condition in fail-safe mode

Fail safe mode

Vehicle behavior

Others

• ECM illuminates engine 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.
