Kia Sportage: Fuel Delivery System / Fuel Pressure Sensor (FPS) Description and operation
The fuel pressure sensor (FPS) is installed on the top of the low pressure fuel
pump and measures the pressure in the low pressure fuel line.Based on the fuel
pressure measured by the FPS and the amount of fuel consumed, the fuel pump
control module (FPCM) determines whether to activate the low pressure fuel pump.After
activating the low pressure fuel pump, the FPS continues to provide the fuel
pressure information to the FPCM and the FPCM keeps controlling the fuel flow
rate using the feedback information from the FPS.
