P0524 ENGINE OIL PRESSURE

P0524 ENGINE OIL PRESSURE

DTC Description

INFOID:0000000011278075

DTC DETECTION LOGIC

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-365, "Diagnosis Procedure"

” is unfinished, be sure to perform Step 3 and 4.

1.

PRECONDITIONING-1

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 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

1. Start engine and warm it up to normal operating temperature.

2. Maintain the following conditions for about 10 consecutive seconds.

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

EC-365, "Diagnosis Procedure"

.

NO

>> INSPECTION END

DTC No.

6. Check “COOLAN TEMP/S” indication value.

With GST

Follow the procedure “With CONSULT” above.
Is the value of “COOLAN TEMP/S”

−5°C (23°F) and 45°C (113°F)?

YES

>> GO TO 3.

NO-1 [if it is below 

− 5°C (23°F)]>>Warm up the engine until the value of “COOLAN TEMP/S” indicates −5°C

(23

°F) and 45°C (113°F). And then GO TO 3.

NO-2 [if it is above 45

°C (113°F)]>>Cool the engine down to the value of “COOLAN TEMP/S” indicates −5°C

(23

°F) and 45°C (113°F). And then GO TO 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE-I

1. Turn ignition switch OFF and wait at 10 seconds.
