1. INSPECT MASS AIR FLOW METER

  1. Output voltage inspection.

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

    2. Connect the position (+) 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.

  1. Resistance inspection.

    1. Using an ohmmeter, measure the resistance between terminals 4 (THA) and 5 (E2).

      Resistance:
      Symbols (Terminal No.)
      		Resistance
      		Temperature
      THA (4) - E2 (5)
      		13.6 to 18.4 kΩ
      		-20° (-4°F)
      THA (4) - E2 (5)
      		2.21 to 2.69 kΩ
      		20° (68°F)
      THA (4) - E2 (5)
      		0.49 to 0.67 kΩ
      		60° (140°F)
