Description & Operation: 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.
