Hyundai Kona: Fuel Delivery System / Fuel Pump Control Module (FPCM) Description and operation

Hyundai Kona (OS) 2018-2025 Service Manual / Engine Control / Fuel System / Fuel Delivery System / Fuel Pump Control Module (FPCM) Description and operation

Description

The fuel pump control module (FPCM) is installed on the right side of the fuel tank 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.

Operation

1.	The ECM provides target fuel pressure information to the FPCM via CAN network.

The FPS provides the FPCM with actual pressure information of the low pressure fuel line between the low and high pressure fuel pumps, and the FPCM forwards the information to the ECM.Also, the FPCM diagnoses faults in the FPCM, fuel pump motor and FPS and then provides the diagnosis information to the ECM.

The FPCM compares the actual fuel pressure information measured by the FPS with the target fuel pressure information provided by the ECM and controls the voltage that is provided to the low pressure fuel pump motor.The FPCM keeps regulating fuel flow rate by controlling the low pressure fuel pump, depending on engine speed (rpm) and vehicle loads.
