    1. Apply battery voltage across terminals 1 (+B) and 2 (E2G).

      NOTICE:
      While using the battery during inspection, do not bring the positive and negative tester probes too close to each other as a short circuit may occur.
    2. Using a voltmeter, connect the positive (+) tester probe to terminal 3 (VG), and negative (-) tester probe to terminal 2 (E2G).

    3. Blow air into the MAF meter, and check that the voltage fluctuates.
      If the result is not as specified, replace the MAF meter.

  1. 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.
    If the result is not as specified, replace the mass air flow meter.


  1. Check the IAT 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)
      0.5 to 0.68 kΩ
      If the result is not as specified, replace the MAF meter.
