Hyundai Genesis: Fuel Delivery System / Fuel Pressure Sensor (FPS) Description and Operation
The fuel pressure sensor (FPS) is installed on top of the low
pressure fuel pump and measures the pressure of the low pressure fuel
line. Based on the current fuel pressure 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 communicate with the FPCM to measure the
fuel pressure and control the supply of low pressure fuel.

Inspection
1.
Connect the GDS on the Data Link Connector (DLC).
2.
If there is DTC on the GDS, replace the FPCM.
3.
Check the output voltage of fuel pressure sensor (FPS).
