INSPECTION
1. VISUALLY INSPECT LINES AND CONNECTIONS
Look for loosen connections, sharp bends or damage.
2. VISUALLY INSPECT FUEL TANK
Look for deformation, cracks or fuel leakage.
3. VISUALLY INSPECT FUEL TANK CAP
Check if the cap and/or gasket are deformed or damaged.
If necessary, repair or replace the cap.
4. REMOVE VSV
Remove the screw from the charcoal canister.
5. REMOVE CHARCOAL CANISTER
6. REMOVE CAP FROM CHARCOAL CANISTER
7. VISUALLY INSPECT CHARCOAL CANISTER
Look for cracks or damage.
8. INSPECT FOR CLOGGED FILTER AND STUCK
CHECK VALVE
(a) Using low pressure compressed air (4.71 kPa, 48 gf/cm
2,
0.68 psi), blow into tank pipe and check that air flows with-
out resistance from the other pipes.
(b) Blow air (4.71 kPa, 48 gf/cm
2, 0.68 psi) into purge pipe
and check that air does not flow from the tank pipe and air
flows without resistance from the other pipe.
If a problem is found, replace the charcoal canister.

PRECAUTION
1. BEFORE WORKING ON FUEL SYSTEM, DISCON-
NECT NEGATIVE (−) TERMINAL CABLE FROM BAT-
TERY
HINT:
Any diagnostic trouble code retained by the ECM will be erased
when the battery negative (−) terminal cable is removed from
the battery.
Therefore, if necessary, read the diagnostic trouble code(s) be-
fore removing the negative (−) terminal cable from the battery.
2. DO NOT SMOKE OR WORK NEAR AN OPEN FLAME
WHEN WORKING ON FUEL SYSTEM
3. KEEP GASOLINE AWAY FROM RUBBER OR LEATH-
ER PARTS
4. MAINTENANCE PRECAUTIONS
(a) Precaution when the connecting gauge.
Use battery as the power source for the timing light, etc.
(b) In the event of engine misfire, these precautions should
be taken.
(1) Check proper connection of battery terminals, etc.
(2) Handle high−tension cords carefully.
(3) After repair work, check that the ignition coil termi-
nals and all other ignition system lines are recon-
nected securely.
(4) When cleaning the engine compartment, be espe-
cially careful to protect the electrical system from
water.
(c) Precautions when the handling heated oxygen sensors.
(1) Do not allow oxygen sensor to drop or hit against an
object.
(2) Do not allow the sensor to come into contact with
water.
If Vehicle is Equipped with Mobile Radio System (ham, cb, etc.)
If the vehicle is equipped with a mobile communication system,
refer to the precaution in the IN section.
5. AIR INDUCTION SYSTEM
(a) Separation of the engine oil dipstick, oil filler cap, PCV
hose, etc. may cause the engine to run out of tune.
(b) Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head will cause air suction and cause the engine to run
out of tune.

6. INSPECT FUEL RECEIVER GAUGE RESISTANCE
Measure the resistance between terminals.
w/ Tachometer:
Between terminalsResistance (Ω)
A − BApprox. 137.0
A − CApprox. 123.0
B − CApprox. 260.0
w/o Tachometer:
Between terminalsResistance (Ω)
A − BApprox. 150.0
A − CApprox. 80.0
B − CApprox. 55.0
If resistance value is not as specified, replace the receiver
gauge.
7. INSPECT FUEL SENDER GAUGE OPERATION
(a) Connect a series of three 1.5 V dry batteries.
(b) Connect the positive (+) lead from the dry cell batteries to
terminal 2 through a 3.4 W test bulb and the negative (−)
lead to terminal 1.
(c) Check the positive (+) lead from the voltmeter to terminal
2 and the negative (−) lead to terminal 1.
(d) Check that the voltage rises as the float is moved from the
top to bottom position.
If operation is not as specified, replace the sender gauge.
8. INSPECT FUEL SENDER GAUGE RESISTANCE
Measure the resistance between terminals 1 and 2.
Float position (mm)Resistance (Ω)
F : Approx. 95.0F : Approx. 3.0
1 / 2 : Approx. 188.01 / 2 : Approx. 32.5
E : Approx. 283.0E : Approx. 110.0
If resistance value is not as specified, replace the sender
gauge.
9. INSPECT FUEL LEVEL WARNING LIGHT
(a) Disconnect the connector from the sender gauge.
(b) Connect terminals 1 and 4 on the wire harness side con-
nector.
(c) Turn the ignition switch ON, check that the warning light
lights up.
If the warning light does no light up, test the bulb.
