FuelTank Vapor Control Valve Test
Special Tools Required
Vacuum Pump/Gauge, 0-30 in. Hg A973X-041-XXXXX
Float Test
1. Make sure the fuel tank is less than half full.
2. Remove the fuel fill cap to relieve fuel tank
pressure, then reinstall the cap.
3. Disconnect the fuel tank vapor recirculation tube
{A), and connect a vacuum PumP to it.
Plug the line (B).
Apply vacuum to the fuel tank vapor recirculation
tuDe.
lf the vacuum holds, replace the fuel tank vapor
control valve (see page 11-189).
lf the vacuum does not hold, the float is OK. Do
the valve test.

10.
Fill the fuel tank with fuel, then check for fuel in theEVAP two way valve (A), and fuel tank vaporrecirculation hose (B).
NOTE: At either location, tiny droplets of fuel arenormal.
. lf fuel runs out of th e hoses at either location,
replace the fuel tank vapor control valve..lfthefuel does not run out of the hoses, the fuel
tank vapor system function is normal.
Disconnect the fuel tank vapor quick disconnectfrom the EVAP canister, then plug lhe port on the
canister. Reapply vacuum (80 pumps).
. lf the vacuum holds, replace the fuel tank control
valve (see page 1 1-189).. lf the vacuum does not hold, insDect the EVAP
canister vent shut valve o-ring. lf the o-ring is OK,replace the EVAP canister, and repeat step 4.
Check for fuel rirnning out.
Check for fuel running out.

steering wheel from the steering column shaft by
turning the pressure bolt (C) ofthe puller.
Note these items when removing the steering
wheel:. Do not tap on the steering wheel orthesteering
column shaft when removing the steering wheel.. lf you thread the puller bolts (D) intothewheel
hub more than 5 threads, the bolts will hit the
cable reel and damage it. To prevent this, install
a pair of jam nuts 5 threads up on each puller bolt.

1. Before installing the steering wheel, make sure the
front wheels are aligned straight ahead, then center
the cable reel (A). Do this by first rotating the cable
reel clockwise until it stops. Then rotate it
counterclockwise about two and a half turns. The
arrow mark (B) on the cable reel label should point
straight up.
Position the two tabs (A) of the turn signal
canceling sleeve (B) as shown. Installthe steering
wheel onto the steering column shaft, making sure
the steerlng wheel hub (C) engages the pins (D) of
the cable reel and tabs of the canceling sleeve. Do
not tap on the steering wheel or steering column
shaft when installing the steering wheel.
