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 tube connections are as shown in the illustra-
tion.
If a problem is found, repair or replace the part as necessary.

INSPECTION
1. INSPECT MAF METER RESISTANCE
Using an ohmmeter, measure the resistance between terminals
THA and E2.
Resistance:
-20°C (-4°F)10 - 20 kW
0°C (32°F)4 - 7 kW
20°C (68°F)2 - 3 kW
40°C (104°F)0.9 - 1.3 kW
60°C (140°F)0.4 - 0.7 kW
If the resistance is not as specified, replace the MAF meter.
2. INSPECT MAF METER OPERATION
(a) Connectfthe MAF meter connector.
(b) Connectfthe negative (-) terminal cable to the battery.
(c) Using a voltmeter, connect the positive (+) tester probe to
terminal VG, and negative (-) tester probe to terminal
E21.
(d) Turn the ignition switch ON.
(e) Blow air into the MAF meter, and check that the voltage
fluctuates.
If operation is not as specified, replace the MAF meter.
(f) Turn the ignition switch OFF.
(g) Disconnect the negative (-) terminal cable from the bat-
tery.
(h) Disconnect the MAF meter connector.

THROTTLE BODY
ON-VEHICLE INSPECTION
1. INSPECT THROTTLE BODY
(a) Check that the throttle linkage moves smoothly.
(b) Check the vacuum at the purge port.
Start the engine.
Check the vacuum with your finger.
Port nameAt idleAt 3,000 rpm
PurgeNo vacuumVacuum
2. INSPECT DASHPOT
(a) Warm up engine.
Allow the engine to warm up to normal operating tempera-
ture.
(b) Check idle speed.
Idle speed (Transmission in neutral position):
650 ± 50 rpm
(c) Check and adjust dashpot setting speed.
(1) Disconnect the control cables from the throttle
body.
(2) Turn the throttle linkage until the dashpot adjusting
screw starts to separate from the push rod. Then
keep the throttle linkage at that position.
(3) Check that the dashpot is set.
Dashpot setting speed: 2,300 ± 400 rpm
(4) Reconnect the control cables to the throttle body.
(d) Check VTV operation
(1) Maintain the engine speed at 3,500 rpm.
(2) Release the throttle valve, and check that the en-
gine returns to idle in a few seconds.
