- [03\-002\-17\-3394](/bulletins/10188487.md), 2021-03-08, Service bulletin: ENGINE AND ENGINE COOLING:ENGINE:OIL/LUBRICATION; FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP:MOUNTING PLATE/FLANGE; EQUIPMENT. Some vehicles may exhibit an oil leak from the companion flange area \(A\) of the transfer unit. This concern may be caused by companion flange oil seal wear. The oil seal has been improved to increase the wear resistance.
- [01\-002\-15\-3005](/bulletins/10100720.md), 2017-05-25, Service bulletin: FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP. SOME VEHICLES MAY EXHIBIT A TAPPING NOISE COMING FROM INSIDE THE FUEL TANK \(UNDER THE REAR SEAT\) WHEN IDLING AFTER THE FUEL TANK HAS BEEN FILLED UP. THE NOISE DISAPPEARS AFTER DRIVING AND CONSUMING SOME FUEL. THE CONCERN WILL LIKELY OCCUR IF THE FUEL TANK IS OVERFILLED \(MORE FUEL IS ADDED AFTER THE FUEL PUMP NOZZLE SHUTS OFF AUTOMATICALLY\) OR FILLED UP NORMALLY IN HIGH AMBIENT TEMPERATURES AND THE FUEL EXPANDS. THIS NOISE IS CAUSED WHEN THE FLOAT INSIDE THE ROLL OVER VALVE \(ROV\) MOVES UP AND DOWN WHEN THE TANK IS OVERFILLED. TO CORRECT THE PROBLEM, THE ROV HAS BEEN MODIFIED TO RESTRICT THE UP AND DOWN MOVEMENT OF THE FLOAT.
- [01\-002\-15\-3005A](/bulletins/10099409.md), 2017-05-17, Service bulletin: FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP. SOME VEHICLES MAY EXHIBIT A TAPPING NOISE COMING FROM INSIDE THE FUEL TANK \(UNDER THE REAR SEAT\) WHEN IDLING AFTER THE FUEL TANK HAS BEEN FILLED UP. THE NOISE DISAPPEARS AFTER DRIVING AND CONSUMING SOME FUEL. THE CONCERN WILL LIKELY OCCUR IF THE FUEL TANK IS OVERFILLED \(MORE FUEL IS ADDED AFTER THE FUEL PUMP NOZZLE SHUTS OFF AUTOMATICALLY\) OR FILLED UP NORMALLY IN HIGH AMBIENT TEMPERATURES AND THE FUEL EXPANDS. • FOR JAPAN BUILT MODELS: THIS NOISE IS CAUSED WHEN THE FLOAT INSIDE THE ROLL OVER VALVE \(ROV\) MOVES UP AND DOWN WHEN THE TANK IS OVERFILLED. TO CORRECT THE PROBLEM, THE ROV HAS BEEN MODIFIED TO RESTRICT THE UP AND DOWN MOVEMENT OF THE FLOAT. • FOR MEXICO BUILT MODELS: THE NOISE IS CAUSED BY AIR BUBBLES FROM THE SHUT OFF VALVE \(SOV\) WHEN THE FUEL TANK IS OVERFILLED. TO CORRECT THE PROBLEM, THE SOV HAS BEEN IMPROVED TO PREVENT THIS CONCERN.
- [01\-024\-12\-2729](/bulletins/10097863.md), 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.
