Inspection

INSPECT MASS AIR FLOW METER

a. Check the operation.




1. Apply battery voltage across terminals 1 (+B) and 2 (E2G).
2. Using voltmeter, connect the positive (+) tester probe to terminal 3 (VC), and negative (-) tester probe to terminal 2 (E2G).
3. Blow air into the mass air flow sensor, then check that the voltage fluctuates.

If the operation is not as specified, replace the mass air flow sensor.

b. Inspect the resistance.







1. Using an ohmmeter, measure the resistance between the terminals.

If the resistance is not as specified, replace the mass air flow sensor.
