    2. Apply and maintain vacuum of 29.3 to 40.4 kPa (220 to 300 mmHg) to the fuel heater assembly.

    3. 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)
      		0.5 to 2.0 Ω

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