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


      1. Measure the resistance between terminal 2 and the heater body.

      2. Apply a vacuum of 29 to 40 kPa (218 to 300 mmHg, 8.56 to 11.8 in.Hg) or higher to the vacuum switch port.

        Standard Resistance
        Tester Connection Condition Specified Condition
        2 - Heater body 20°C (68°F) 0.5 to 2.0 Ω

        If the result is not as specified, replace the fuel heater assembly.

  2. INSPECT FUEL FILTER CAP ASSEMBLY (w/ Clogging Switch)


    1. Inspect the clogging switch.


      1. Measure the resistance according to the value(s) in the table below.

        Standard Resistance
        Tester Connection Condition Specified Condition
        1 - 2 20°C (68°F) Below 1 Ω

        If the result is not as specified, replace the fuel filter cap assembly.
