    INSPECT MASS AIR FLOW METER SUB-ASSEMBLY


    1. A0005J1E11

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

      Table 1. Text in Illustration
      *1 Platinum Hot Wire (Heater)
      OK
      There is no foreign matter.

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


      1. A0004ZNE12

        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
        1 (THA) - 2 (E2) 20°C (68°F) 2.21 to 2.69 kΩ
        1 (THA) - 2 (E2) 60°C (140°F) 0.49 to 0.67 kΩ
