  3. Disconnect the electrical connector (1).

    4. Caution: Refer to Fuel and Evaporative Emission Hose/Pipe Connection Cleaning Caution.

    Note:

    • Do NOT apply force to the plastic housing of the fuel injection fuel rail fuel pressure sensor. ONLY apply force to the attached hexagon.
    • Some fuel may leak from the fuel injection fuel rail orifice after the sensor is removed. Dry the area around the orifice using a lint free cloth.
    • After removal, the area around the fuel injection fuel rail sealing surface should be inspected. The surface should be free of fuel, dirt, debris, and burrs.

  4. Remove and DISCARD the fuel injection fuel rail fuel pressure sensor (2).
Installation Procedure

    Object ID: 4180364

    Caution: Refer to Component Fastener Tightening Caution.

    Note:

    • Do NOT apply force to the plastic housing of the fuel injection fuel rail fuel pressure sensor. ONLY apply force to the attached hexagon.
    • BEFORE installation of the fuel injection fuel rail fuel pressure sensor, the fuel injection fuel rail threads MUST be clean and free of any fuel or the sensor will NOT seal properly.

  1. To install the NEW fuel injection fuel rail fuel pressure sensor (2) properly, perform the following steps:
    1. Lubricate the sensor threads and sealing surface with one drop of clean engine oil.
    2. Install the sensor and hand tighten.
    3. Remove the sensor.
    4. Re-lubricate the sensor threads and sealing surface with one drop of clean engine oil.
    5. Install the sensor and tighten to 33 N·m  (24 lb ft).
  2. Connect the electrical connector (1).

    3. Note: If a fuel leak occurs at the fuel injection fuel rail, the fuel rail will need to be replaced.

  3. Pressurize the fuel system and inspect for leaks.
