| 00-003-19-3583 | 2019-03-21. Service bulletin. FUEL SYSTEM, DIESEL:STORAGE:TANK ASSEMBLY; FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING; EQUIPMENT. In support of the new MRT distribution, Mazda will ship to dealers a new Dual Purpose Diagnostic Leak Detector beginning March, 2019. Training videos will be posted to MGSS shortly and Workshop Manual procedures will be revised gradually. |
| 01-005-18-3415 | 2018-05-07. Service bulletin. FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING:EXHAUST SYSTEM. Some vehicles may experience a rough idle with the check engine light 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 oil control valve (OCV). The temporary entry of the foreign object triggers a check engine light on, but rough idle will not be produced until a later time. |
| RF-16-03R1 | 2018-04-23. Service bulletin. FUEL SYSTEM, OTHER:FUEL FILTER. The SKYACTIV®-G 2.5T engine requires a unique oil filter (PY8W-14-302) which is NOT interchangeable with other SKYACTIV® oil filters. The unique oil filter can be identified with two white bands as shown below. |
| 01-013-15-3048 | 2017-05-17. Service bulletin. FUEL SYSTEM, OTHER:STORAGE:TANK ASSEMBLY. SOME CUSTOMERS MAY COMPLAIN THAT THE FUEL TANK IS DIFFICULT TO FILL UP. THIS CONCERN MAY BE CAUSED BY IMPROPER OPERATION OF THE NON-RETURN VALVE IN THE FUEL TANK (TEMPORARILY STUCK OPEN). THE PRODUCTION PROCESS OF THE FUEL TANK HAS BEEN IMPROVED TO ELIMINATE THIS CONCERN. |
| 01-014-14-2932 | 2017-05-04. Service bulletin. FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY:FILLER PIPE AND CAP; ENGINE. SOME VEHICLES MAY EXHIBIT THE CHECK ENGINE LIGHT ON WITH DTC P0456 STORED IN THE PCM MEMORY.• P0456: EVAP SYSTEM LEAK DETECTED (VERY SMALL LEAK) THE CONCERN IS MOST LIKELY THE RESULT OF THE CUSTOMER NOT GETTING THE FUEL CAP COMPLETELY CLOSED AFTER FUELING THE VEHICLE. THIS CAUSES A SMALL FUEL VAPOR LEAK AND TURNS DTC P0456 ON. |
| 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. |
