СИСТЕМА ECD


  1. CONSTRUCTION


    1. The fuel pressure sensor, which is mounted on the common-rail assembly, outputs a signal that represents the fuel pressure in the common-rail assembly to the ECM in order to constantly regulate the fuel at an optimal pressure.

    2. The fuel pressure sensor consists of a semiconductor which utilizes the characteristics of a silicon chip that changes its electrical resistance when pressure is applied to it.

      Tech Tips

      When the fuel pressure sensor malfunctions, the ECM stores data about the malfunction. Also, the ECM regulates the fuel pressure using the default value.
