At the end of the vehicle's oil return line. The fuel pressure sensor of the vehicle is also called the fuel pressure regulator. During normal operation, it is mainly responsible for accurately controlling the fuel pressure in the vehicle's oil circuit, so that the injector can maintain a stable oil pressure value. And it can also send excess fuel back to the fuel tank to reduce the waste of oil. In the process of daily driving, the vehicle is prone to air leakage in the intake pipe, which leads to the failure of the function of the fuel pressure sensor. After this situation occurs, the first thing the driver needs to do is to check the connection to the alarm line. It is likely to be caused by poor contact in the wiring or interference in the line; Whether the high-pressure and low-pressure fuel pressures are normal may be due to the failure of the intake pipe damper position sensor or its circuit, which causes damage to the structural unit inside the sensor; if there is no failure in these two places, you need to go to a professional Auto repair shop for overhaul processing.
