MASS AIR FLOW METER INSPECTION


  1. INSPECT MASS AIR FLOW METER SUB-ASSEMBLY


    1. A01GIV4E05

      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. A01GJCNE05

      Check the intake air temperature sensor (Built into the MAF meter).


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

        Standard resistance
        Tester Connection Condition Specified Condition
        5 (THA) - 4 (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.
