ECD SYSTEM


  1. CONSTRUCTION


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

    2. The fuel pressure sensor contains 2 circuits (main and sub), which enable the ECM to constantly compare the values detected by the 2 circuits. As a result of this comparison, the ECM can determine that a fault exists, allowing fail-safe control to occur.
