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
FAIL-SAFE
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.
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
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
Monitor item | Condition | Value (Approx.) | |
EOP SENSOR |
|
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".

NO >> Repair or replace error-detected parts.
5.CHECK CAUSE OF ENGINE OIL CONSUMPTION
Check the following item.
>> Repair or replace error-detected parts.
6.CHECK INTERMITTENT INCIDENT
Refer to GI-41, "Intermittent Incident".
>> INSPECTION END
Component Inspection
1.CHECK EOP SENSOR
Is the inspection result normal? YES >> INSPECTION END.
NO >> Replace EOP sensor. Refer to EC-14, "Component Parts Location".
