NOTE:
If DTC P0524 is displayed with DTC P0520 or P0075, perform trouble diagnosis for DTC P0520 or P0075
first. Refer to
.
DTC CONFIRMATION PROCEDURE
CAUTION:
If “Diagnosis Procedure” is unfinished, be sure to perform Step 3 and 4.
1.
PRECONDITIONING-I
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.
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.
>> GO TO 2.
2.
PRECONDITIONING-II
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
.
Is the inspection result normal?
YES
>> GO TO 4.
NO
>> Proceed to
4.
CHECK ENGINE OIL PRESSURE
WITH CONSULT
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode of “ENGINE” using CONSULT.
3. Start the engine and check that “EOP SENSOR” changes, according to engine speeds.
Without CONSULT
DTC No.

ENGINE OIL PRESSURE
(Engine oil pressure too low)
An engine oil pressure 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.
• Decrease in engine oil pressure
• Decrease in engine oil level
• Engine oil condition
• Engine oil pressure sensor
• Engine body
