Air Flow Meter/Sensor: Testing and Inspection

1. Connect ohmmeter between pins 12 and 26.
2. Correct resistance reading is 300-550 ohms.
3. Connect ohmmeter between pins 7 and 26.
4. Correct resistance reading is 10-20 ohms.
5. Move flap in and out. No continuity should be present between pins 7 and 26.
6. Connect ohmmeter between pins 26 and 44.
7. Correct resistance reading, at varying temperatures is:
a. At 14°F; 8260-10560 ohms.
b. At 68°F; 2280-2720 ohms.
c. At 122°F; 760-910 ohms.
