Hello, the fuel pressure sensor is an important part of the engine control system, its main role is to monitor the change of fuel pressure, and transmit these data to the engine control module in order to adjust the fuel injection amount and time, so as to ensure the normal operation of the engine. When the fuel pressure sensor fails, it will have the following effects on the vehicle:
1. Engine starting difficulty: The fuel pressure sensor cannot correctly monitor the change of fuel pressure, which may cause the engine to start difficult or completely unable to start.
2. Engine power drop: Fuel pressure sensor failure may lead to inaccurate fuel injection amount and time, so that the engine power drop, acceleration is not sensitive enough.
3. Vehicle flameout: The failure of the fuel pressure sensor may lead to insufficient fuel supply, making the vehicle flameout while driving.
4. Increased fuel consumption: The failure of the fuel pressure sensor may lead to inaccurate fuel injection amount and time, which increases the fuel consumption of the vehicle.
5. Increased pollution emissions: The failure of the fuel pressure sensor may lead to incomplete fuel combustion, resulting in more exhaust emissions and pollution to the environment.
