INSPECTION

INSPECT FUEL TANK AND LINE
(a)

Check the fuel lines for cracks or leakage, and all connec-
tions for deformation.

(b)

Check the fuel tank vapor vent system hoses and connec-
tions for looseness, sharp bends or damage.

(c)

Check the fuel tank for deformation, cracks, fuel leakage
or tank band looseness.

(d)

Check the filler neck for damage or fuel leakage.

(e)

Hose and pipe connections are as shown in the illustra-
tion.

If a problem is found, repair or replace the parts as necessary.

INSPECTION

1.

INSPECT OUTPUT VOLTAGE

(a)

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

(b)

Connect the positive (+) tester probe to terminal 3 (VG),
and the negative (–) tester probe to terminal 2 (E2G).

(c)

Blow air into the MAF meter, and check if the voltage fluc-
tuates.

2.

INSPECT RESISTANCE

Using an ohmmeter, measure the resistance between terminals
4 (THA) and 5 (E2).

Resistance:
12.5 to 16.9 k

3.

INSPECT MASS AIR FLOW METER

(a)

If using a hand–held tester:
(1)

Connect the hand–held tester to the DLC3.

(2)

Turn the ignition switch to the ON position.

(3)

Blow air into the MAF meter, and check that the air
flow value of the CURRENT DATA changes.

If operation is not as specified, check the MAF meter (see page

DI–110

 and 

DI–113

) as well as the wiring and the ECM.

(b)

If not using a hand–held tester:
(1)

Turn the ignition switch to the ON position.

(2)

Connect the positive tester probe of the voltmeter
to terminal VG of the ECM and the negative tester
probe of the voltmeter to terminal E2G of the ECM.

(3)

Blow air into the air flow meter, and check if the volt-
age fluctuates.

If operation is not as specified, check the MAF meter (see page

DI–110

 and 

DI–113

), the wiring and the ECM.
