DESCRIPTION
Some vehicles may experience a rough idle with the check engine light on and DTC P0015 / P0524 stored in memory.
This is caused by a drop in engine oil pressure due to a piece of foreign object stuck on the oil pump pressure relief valve or OCV. The temporary entry of the foreign object triggers a MIL illumination, but rough idle will not be produced until a later time.
Customers having this concern should have their vehicle repaired using the following flow charts and repair procedure.

Only P0015 is stored:
P0015 and P0524 or only P0524 is stored:
REPAIR PROCEDURE
- Verify customer concern.
Only P0015 is stored:
- Delete the DTC.
- Depress the throttle pedal and momentarily adjust the engine speed to 4,000 rpm or more for 10 times.
- Measure the main line oil pressure at 650 rpm, 1,500 rpm and 4,500 rpm according to the instructions on MS3 (OIL PRESSURE INSPECTION).
a. Connect M-MDS or Scan Tool to monitor ECT, OIL_TEMP and RPM.
b. Start the engine and turn off all electrical loads such as A/C, headlights, etc.
c. Warm up the engine until ECT and OIL_TEMP reach 90 °C (194 °F) or more.
d. Turn off all electrical loads such as A/C and headlights.
e. Wait until RPM on IDS or Scan Tool becomes stable at 650 rpm. DO NOT read RPM on the tachometer in the vehicle.
f. Measure and write down the main oil line pressure at 650 rpm, 1,500 rpm and 4,500 rpm.
| RPM | Normal oil pressure |
| 650 | 50 kpa (7 psi) or more |
| 1,500 | 110-175 kpa (16.0 – 25.3 psi) |
| 4,500 | 300-430 kpa (43.6 – 62.3 psi) |
- If Abnormal oil pressure is observed:
1) Replace the oil pump with a new one and replace the oil strainer with a modified one. Refer to MS3 online instructions or Workshop Manual section 01-11.
NOTE: The removal procedure for the oil pump in the Workshop Manual has been changed. It is no longer necessary to remove the front cover when following the new procedure.
2) Clean the bottom of the oil pan with a clean cloth.
3) Erase any DTC’s.
4) Replace the engine oil.
NOTE: There is no need to replace the oil filter or oil pan.
- If Normal oil pressure is observed:
1) Verify that the difference of VT_EX_DES (Exhaust valve opening angle – target) and VT_EX-ACT (Exhaust valve opening angle – actual) is within 5 degrees (between 1,500 rpm and 2,000 rpm) using M-MDS.
- Within 5 degrees:
1) Replace the oil strainer with a modified one.
2) Clean the bottom of the oil pan with a clean cloth.
3) Replace the engine oil.
NOTE: There is no need to replace the oil filter or oil pan.
- Over 5 degrees:
1) Replace the oil control valve (OCV).
2) Replace the oil strainer with a modified one.
3) Clean the bottom of the oil pan with a clean cloth.
4) Replace the engine oil.
NOTE: There is no need to replace the oil pump, oil filter or oil pan.
- Verify repair.
P0015 and P0524 or only P0524 is stored:
- Delete the DTC.
- Depress the throttle pedal and momentarily adjust the engine speed to 4,000 rpm or more for 10 times.
- Measure the main line oil pressure at 650 rpm, 1,500 rpm and 4,500 rpm according to the instructions on MS3 (OIL PRESSURE INSPECTION).
a. Connect M-MDS or Scan Tool to monitor ECT, OIL_TEMP and RPM.
b. Start the engine and turn off all electrical loads such as A/C, headlights, etc.
c. Warm up the engine until ECT and OIL_TEMP reach 90 °C (194 °F) or more.
d. Turn off all electrical loads such as A/C and headlights.
e. Wait until RPM on IDS or Scan Tool becomes stable at 650 rpm. DO NOT read RPM on the tachometer in the vehicle.
f. Measure and write down the main oil line pressure at 650 rpm, 1,500 rpm and 4,500 rpm.
| RPM | Normal oil pressure |
| 650 | 50 kpa (7 psi) or more |
| 1,500 | 110-175 kpa (16.0 – 25.3 psi) |
| 4,500 | 300-430 kpa (43.6 – 62.3 psi) |
- If Abnormal oil pressure is observed:
1) Replace the oil pump with a new one and replace the oil strainer with a modified one according to the instructions on MS3 (OIL PUMP REMOVAL/INSTALLATION).
NOTE: The removal procedure for the oil pump in the Workshop Manual has been changed. It is no longer necessary to remove the front cover when following the new procedure.
2) Clean the bottom of the oil pan with a clean cloth.
3) Erase any DTCs.
4) Replace the engine oil.
NOTE: There is no need to replace the oil filter or oil pan.
- If Normal oil pressure is observed:
1) Replace the oil strainer with a modified one.
2) Clean the bottom of the oil pan with a clean cloth.
3) Replace the engine oil.
NOTE: There is no need to replace the oil pump, oil filter or oil pan.
