Kia Sportage: Fuel Delivery System / Fuel Pump Control Module (FPCM) Description and operation
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.


1. |
The ECM provides target fuel pressure information to the FPCM via CAN
network.
|
2. |
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.
|
3. |
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.
