Summary
SOME VEHICLES MAY EXPERIENCE THE CHECK ENGINE LIGHT ON WITH DTC P0191:00 OR DTC P0192:00 STORED IN MEMORY. DTC P0191:00: FUEL PRESSURE SENSOR CIRCUIT RANGE/PERFORMANCE PROBLEM (EXCEPT 2014 MAZDA3) DTC P0192:00: FUEL PRESSURE SENSOR CIRCUIT LOW INPUT (2014 MAZDA3) THIS IS CAUSED BY THE HIGH PRESSURE FUEL PUMP NOT GENERATING THE TARGET FUEL PRESSURE (DUE TO A MANUFACTURING ERROR OF THE INNER PARTS). TO CORRECT THE PROBLEM, PRODUCTION CONTROL HAS BEEN IMPROVED.
