1. Take measures to prevent gasoline leaking
(see Page 14)
2. Remove rear seat cushion assembly
3. Remove rear floor repairing hole cover
4. Remove No. 2 fuel evaporation assembly
5. Remove fuel tank main fuel hose and oil return pipe
assembly
6. Remove fuel pump assembly
7. Discharge fuel
8. Remove front floor bracket
9. Remove front exhaust pipe assembly
(a) Move away carpet and remove oxygen sensor joint.
(b) Remove front exhaust pipe assembly
10.Disassemble the vent pipe of fuel hose
11.Disassemble filler pipe from fuel tank
12.Remove No. 2 fuel evaporator hose assembly
Press fuel hose joint and then pull out the hose.
Notes:
Check there is contaminant that looked like dirt around the
joint before operating and clean it off in the case of
contaminant.
Be careful of the contaminant that looked like dirt, because
fast-joint depends on o-ring to seal fuel pipe and joint.
Do not perform this operation with tools.
Do not bend or distort nylon hose.
Cover the joint with plastic bag after removing the fuel hose.
When the joint is stuck with fuel pipe, clip the hose with
fingers and rotate carefully to release the hose, and then
remove it.
13.Disassemble fuel tank main fuel hose assembly
Clip the protrusion part of fixing ring and move lock claw toward
open direction, and then pull out the hose as shown in the
diagram.
Notes:
Check there is contaminant looked like dirt around the joint
before operating and clean it off in the case of contaminant.

On-vehicle inspection
1. Check oxygen sensor.
(a) Let the engine run at idle speed for 3 minutes to ensure oxygen sensor reaches operating tempera-
ture of 350
(b) Place digital universal meter at DC voltage gear, and connect 2 terminals respectively to (gray) pin
and (black) pin of sensor, and voltage should fluctuate
quickly between 0.1-0.9V at the moment.
Warning:
Perform inspection immediately after warming
up vehicle.
If voltage change could not be confirmed,
it is necessary to heat oxygen sensor again.

2. Check rotating speed after fuel cut off.
(a) Accelerate engine at least to 3500rpm.
(b) Check the operating noise of injection nozzle with listening device.
(c) When throttle is released, check the operating noise of injection nozzle recovers after stop.
3. Check fuel evaporation exhaust control system.
(a) Check the pipe clamps of connecting pipeline between
charcoal canister and carbon canister solenoid valve are
firmly clipped and check there is leakage.
(b) Check there is trouble with fuel evaporation exhaust con-
trol system with failure diagnostic instrument.
4. Visually check hose, joint and hot fin.
Check cracks, leakage and damage.
Hint: the disconnecting of engine oil level gauge, oil opening
cover and PCV hose may cause running failure of engine.
The cracks, looseness and not connecting at the intake
system between throttle and cylinder head will result in
redundant air entering and running failure of engine.

5. Check heater resistance of heated oxygen sensor.
(a) Uncouple oxygen sensor joint.
(b) Place digital universal meter at ohm gear, and connect 2 terminals respectively to 1# (white) pin and
2# (black) pin, and the resistance under normal temperature is 1 6
6. Check fuel tank cover.
Visually check fuel tank cover and gasket are distorted or damaged.
