BULLETIN NOTE
• This bulletin supersedes the previous bulletins 01-009/14 issued on 04/07/14, 01-003/13 issued on 01/16/13
and 01-028/12 issued on 12/18/12. The REPAIR PROCEDURE and PARTS INFORMATION have been
revised.
• Changes are noted below in Red beside the change bar.
APPLICABLE MODEL(S)/VINS
2012-2014 Mazda3 SKYACTIV
2013-2014 CX-5 SKYACTIV
2014 Mazda6 SKYACTIV
DESCRIPTION
Some vehicles may experience a rough idle with the MIL on and DTC P0015 / 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.

Only P0015 is stored:
1. Delete the DTC.
2. Depress the throttle pedal and momentarily adjust the engine speed to 4,000 rpm or more for 10 times.
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.

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.
RPM
