        (Mass Air Flow Meter)

        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

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