ROUGH IDLE WITH MIL ON AND OTC P0015 I P0524

APPLICABLE MODEL(S)NINS
2012-2013 Mazda3 2.0L SKYACTIV
2013 CX-5

DESCRIPTION
Some vehicles may experience a rough idle with the MIL on and OTC P0015 I P0524 stored in memory.
• P0015:00 - Exhaust CMP timing over-retarded
• P0524:00 - Engine oil pressure too low
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.

3. Measure the main line oil pressure at 650 rpm, 1,500 rpm and 4,500 rpm . Refer to MS3 online instructions
or Workshop Manual section 01-11 OIL PRESSURE INSPECTION.
a. Connect M-MDS 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 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.
