DTC DETECTION LOGIC
DTC No. | CONSULT screen terms (Trouble diagnosis content) | DTC detecting condition | Possible cause |
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 ore more. |

DTC CONFIRMATION PROCEDURE
CAUTION:
If “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.
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 5.
NO >> GO TO 3.
3.CHECK ENGINE OIL LEVEL
Check engine oil level. Refer to LU-7, "Inspection".
Is the inspection result normal? YES >> GO TO 4.
NO >> Proceed to EC-344, "Diagnosis Procedure".
4.CHECK ENGINE OIL PRESSURE
With CONSULT
Without CONSULT
Check engine oil pressure. Refer to LU-7, "Inspection".
Is the inspection result normal? YES >> GO TO 5.
NO >> Proceed to EC-344, "Diagnosis Procedure".
5.PERFORM DTC CONFIRMATION PROCEDURE
NOTE:
With engine speed set around 4,000 rpm, the phenomenon can be reproduced more easily.
Is 1st trip DTC detected? YES >> Proceed to EC-344, "Diagnosis Procedure".
NO >> INSPECTION END

NO >> Replace EOP sensor. Refer to EM-94, "Exploded View".
Rapid air pressure loss
Rapid air pressure loss or a “blow-out” can occur
if the tire is punctured or is damaged due to
hitting a curb or pothole. Rapid air pressure loss
can also be caused by driving on under-inflated
tires.
Rapid air pressure loss can affect the handling
and stability of the vehicle, especially ...
