      *1 Platinum Hot Wire (Heater)

      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 matter.

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

    2. Check the intake air temperature sensor.

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

        Standard Resistance
        Tester Connection Condition Specified Condition
        4 (THA) - 5 (E2) -20°C (-4°F) 12.5 to 16.9 kΩ
        20°C (68°F) 2.19 to 2.67 kΩ
        60°C (140°F) 0.50 to 0.68 kΩ

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