INSPECTION

1. DISCONNECT MAF METER CONNECTOR

2. REMOVE MAF METER

Remove the 2 screws and MAF meter.

3. INSPECT MAF METER

(a) Using an ohmmeter, measure the resistance between terminals THA and E2.

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

(b) Inspect for operation.

1.  Connect the MAF meter connector.
2.  Connect the negative (-) terminal cable to the battery.
3.  Turn the ignition switch ON.
4. Using a voltmeter, connect the positive (+) tester probe to terminal VG and negative (-) tester probe to terminal E2G.
5.  Blow air into the MAF meter, and check that the voltage fluctuates.

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

6. Turn the ignition switch OFF.
7. Disconnect the negative (-) terminal cable from the battery.
8.  Disconnect the MAF meter connector.
