Inspection [12/2019 - ]: Procedure

WARNING: This page is about a different variant/trim than selected.
  1. INSPECT FUEL PRESSURE SENSOR 
    1. Check the fuel pressure sensor output voltage.
      1. Apply 5 V between terminals 1 (VC) and 2 (E2).
        NOTE:
        • Be careful when connecting the leads as the fuel pressure sensor may be damaged if the leads are connected to the wrong terminals.
        • Do not apply more than 6 V to terminals 1 (VC) or 2 (E2).

        HINT: 

        If a stable power supply is not available, connect 4 nickel-metal hydride batteries (1.2 V each) or equivalent in series.

      2. Measure the voltage according to the value(s) in the table below.

        Standard Voltage

        Tester Connection Condition Specified Condition
        3 (PR) - 2 (E2) Pressure not applied to fuel pressure sensor Approximately 0.4 to 0.6 V*

        *: The output voltage changes depending on the voltage applied to the terminals.

        If the result is not as specified, replace the fuel pressure sensor.
