Description & Operation: Description

• The Fuel Pump Control Module (FPCM) controls the DC motor mounted inside the low pressure fuel pump.
• The module compares instantaneous fuel pressure measured by the Fuel Pressure Sensor (FPS) with target fuel pressure provided by the Engine Control Module (ECM) and generates the desired target fuel pressure by controlling the fuel pump motor.
• Diagnoses faults in the FPCM, fuel pump motor and FPS and then provides the diagnostic information to the ECM.
