| 01-023-15-3084B | 2017-06-08. Service bulletin. ENGINE. 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. |

| 01-001-15-2988 | 2017-05-25. Service bulletin. ENGINE. SOME VEHICLES EQUIPPED WITH SKYACTIV-G 2.0L ENGINE MAY EXPERIENCE ENGINE OIL SEEPAGE FROM DRAIN PLUG AFTER THE ENGINE OIL IS REPLACED EVEN IF THE PLUG IS TIGHTENED TO THE SPECIFIED TORQUE WITH A NEW GASKET. OIL PAN DRAIN PLUG TIGHTENING TORQUE: 30—41 N·M {3.1—4.1 KGF·M, 23—30 FT·LBF} SEATING SURFACE OF THE OIL PAN FOR THE DRAIN PLUG MAY HAVE POOR FLATNESS DUE TO IMPROPER SPOT WELDING AND/OR THE SURFACE MAY HAVE GOTTEN A SCRATCH DURING MANUFACTURING PROCESS. |
| 01-014-15-3055 | 2017-05-17. Service bulletin. ENGINE. FREQUENT ENGINE STARTS UNDER EXTREMELY COLD AMBIENT TEMPERATURES MAY RESULT IN OIL SEEPAGE FROM THE ENGINE OIL PRESSURE SWITCH. THIS CONCERN MAY BE CAUSED BY A LACK OF DURABILITY OF THE OIL PRESSURE SWITCH UNDER THESE CONDITIONS. TO CORRECT THE PROBLEM, THE OIL PRESSURE SWITCH HAS BEEN IMPROVED TO INCREASE THE DURABILITY IN COLD AMBIENT TEMPERATURES. ALL SKYACTIV ENGINES EQUIPPED WITH OIL PRESSURE SWITCH PART NUMBER PE01-18-501A ARE APPLICABLE TO THIS ISSUE. |

| 01-024-12-2729 | 2017-04-25. Service bulletin. FUEL SYSTEM, OTHER:DELIVERY:FUEL PUMP; ENGINE. ON CERTAIN 2012 MAZDA3 VEHICLES, WHEN USING HIGH EVAPORATIVE WINTER FUEL, IF THE VEHICLE IS STOPPED AND IDLING FOR LONGER THAN 20 MINUTES, THERE IS A POSSIBILITY THAT THE FUEL INSIDE THE HIGH-PRESSURE FUEL PUMP MAY BE RAISED TO A HIGHER TEMPERATURE THAN USUAL. IF THE FUEL TEMPERATURE IS HIGHER THAN THE FUEL VAPOR TEMPERATURE, THE FUEL SUPPLY TO THE INJECTOR MAY BE INSUFFICIENT AND POTENTIALLY CAUSE ONE OF THE FOLLOWING CONDITIONS: • THE VEHICLE MAY EXPERIENCE ROUGH IDLE AND/OR THE MALFUNCTION INDICATOR LIGHT (MIL) MAY ILLUMINATE WITH DTC P0191:00 (FUEL PRESSURE SENSOR CIRCUIT RANGE/PERFORMANCE PROBLEM) STORED IN THE PCM MEMORY. • THE ENGINE MAY STALL DURING STOP AFTER IDLING FOR A LONG TIME, AND MAY NOT RESTART FOR A CERTAIN PERIOD OF TIME. |
