Second generation VI (2009–2024) / Hyundai Equus VI 2009-2024 Service Manual / Engine Control/Fuel System / Fuel Delivery System / Fuel Pressure Sensor (FPS) Description and Operation
| Description |
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.
