Combined measurement on a fuel pressure sensor and fuel ...

When the key is switched on the fuel pressure sensor shows a low voltage, meaning there is little or no fuel pressure. This low fuel pressure causes the ECU to drive the fuel metering valve with a high duty cycle signal. Once the engine is running the mechanical fuel pump starts to work, which increases the fuel pressure. When the required fuel pressure for idle running is reached, the duty ...

Fuel Pressure Sensor Replacement Service & Cost

In fuel-injected and diesel engines, fuel rail pressure sensors monitor the pressure in the fuel rail and report the reading to the engine control module. If any drop in pressure is detected, the engine control module compensates so that the fuel pump can restore the proper pressure. A valve controls this pressure; if the sensor ever fails, you should replace it. Sometimes, the entire fuel ...
