DTC P0628, P0629 FUEL PUMP
PFP:16700
Description
EBS0158Z
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 Mode
EBS01590
Specification data are reference values.
ECM Terminals and Reference Value
EBS01591
Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
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.
