Inspection

INSPECT MASS AIR FLOW METER

a. Output voltage inspection.




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

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

Resistance:
13.6 - 18.4 kOhm at 20°C (-4°F)
2.21 - 2.69 kOhm at 20°C (68°F)
0.49 - 0.67 kOhm at 60°C (140°F)
