SFI − MASS AIR FLOW (MAF) METER
INSPECTION
1. INSPECT MAF METER RESISTANCE
Using an ohmmeter, measure the resistance between terminals
THA and E2.
Between
terminals
THA − E2
THA − E2
FI6961
THA − E2
THA − E2
THA − E2
THA − E2
If the resistance is not as specified, replace the MAF meter.
2. INSPECT MAF METER OPERATION
(a) Connect the MAF meter connector.
(b) Using a voltmeter, connect the positive (+) tester probe to
terminal VG, and negative (−) tester probe to terminal E3.
(c) Blow air into the MAF meter, and check that the voltage
fluctuates.
If operation is not as specified, replace the MAF meter.
(d) Disconnect the MAF meter connector.
