Mass Air Flow Meter -- Inspection |
| 1. INSPECT MASS AIR FLOW METER ASSEMBLY |
Check the output voltage.
Apply battery voltage across terminals 1 (+B) and 2 (E2G).

(Mass Air Flow Meter)
Air - NOTICE:
- While using the battery during inspection, do not bring the positive and negative tester probes too close to each other as a short circuit may occur.
Using a voltmeter, connect the positive (+) tester probe to terminal 3 (VG) and the negative (-) tester probe to terminal 2 (E2G).
Blow air into the mass air flow meter and check that the voltage fluctuates.
If the result is not as specified, replace the mass air flow meter assembly.
Perform a visual check for any foreign matter on the platinum hot wire (heater) of the mass air flow meter shown in the illustration.
- OK:
- There is no foreign matter.
If the result is not as specified, replace the mass air flow meter assembly.Text in Illustration *1 Platinum Hot Wire (Heater)
