Description
The fuel pump control module (FPCM) is installed on the right
side of the fuel tank on the fuel pump top plate and controls the DC
motor mounted inside the low pressure fuel pump.
The module compares instantaneous fuel pressure information
measured by the fuel pressure sensor (FPS) with target fuel pressure
information provided by the ECM and generates the desired target fuel
pressure by controlling the fuel pump motor and regulating fuel flow
rate in the low pressure fuel line between the low and high pressure
fuel pumps...
