DTC P1273 FUEL PUMP

DTC P1273 FUEL PUMPPFP:16700
DescriptionEBS011DU
To control the amount of the fuel inhalation of the fuel pump, a plunger is built into the fuel pump. When the
amount of the fuel inhalation of fuel pump increases, the fuel raises the fuel exhalation pressure. As a result,
the fuel injection pressure is raised. When the load of the engine increases, the ECM sends a signal to the fuel
pump to raise the injection pressure.
