DTC P0628, P0629 FUEL PUMP

DTC P0628, P0629 FUEL PUMPPFP:16700
DescriptionEBS0122C
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 increases, the fuel pump 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.
CONSULT-II Reference Value in Data Monitor ModeEBS0122D
Specification data are reference values.
ECM Terminals and Reference ValueEBS0122E
Specification data are reference values and are measured between each terminal and ground.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.
