INSPECTION

1. INSPECT MASS AIR FLOW METER

(a) Check the output voltage.

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

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.

(2) Using a voltmeter, 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 that the voltage fluctuates.

If the result is not as specified, replace the MAF meter.

(b) Perform a visual check for any foreign matter on the platinum

OK:

There is no foreign material.

If the result is not as specified, replace the mass air flow meter.
