  1. INSPECT MASS AIR FLOW METER SUB-ASSEMBLY


    1. A01GX28E04

      Perform a visual check for any foreign matter on the platinum hot wire (heater) of the mass air flow meter shown in the illustration.

      OK
      There is no foreign material.

    2. Check the intake air temperature sensor. (Built into the mass air flow meter sub-assembly)


      1. A01H0FRE01

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        1 (THA) - 2 (E2) -20°C (-4°F) 13.6 to 18.4 kΩ
        20°C (68°F) 2.21 to 2.69 kΩ
        60°C (140°F) 0.49 to 0.67 kΩ

        If the result is not as specified, replace the mass air flow meter sub-assembly.
