INSPECTION

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. 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)
