INSPECTION
1. INSPECT MASS AIR FLOW METER
(a) Check the output voltage.
(1) Apply battery voltage across terminals 1 (+B) and 2 (E2G).
(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.
(b) Measure the resistance between terminals 4 (THA) and 5 (E2).
Standard resistance:
|
Condition |
Specified Condition |
|---|---|
|
-20°C (-4°F) |
12.5 to 16.9 kΩ |
|
20°C (68°F) |
2.19 to 2.67 kΩ |
|
60°C (140°F) |
0.50 to 0.68 kΩ |
If the result is not as specified, replace the MAF meter.
