Chapter 3 Fuel SystemSection 1 Check Fuel System PressureOn-board inspection
1. Check the operation of the fuel pump.
(1) Connect the positive and the negative of the battery to
appropriate connector sockets of the fuel pump (see Figure 3-1).
Attention: Do not start the engine.
If there is pressure present, you will hear that the fuel is flowing.
If there is no pressure present, check the fusible cutout, fuse, EFI
open-circuit relay, fuel pump, ECM (Electronic Control Module) and
circuit joint.
(2) Turn the ignition switch to "OFF".
2. Check the pressure of the fuel.
(1) Check whether the battery voltage is more than 12V.
(2) Disconnect the negative wiring cable from the battery.
(3) Mount a pressure gauge on the fuel input pipe
(see Figure 3-2).
(4) Connect the negative terminal of the battery.
(5) Measure the fuel pressure.
Fuel oil pressure: 265-304kPa
If the pressure is low, check the fuel pipe and connection,
fuel pump, and fuel filter. If the pressure is too high,
replace the regulator.
(6) Start the engine. Measure the fuel pressure at idle speed. The
fuel pressure is 265-304KPa. If the pressure is unsatisfactory, checkFigure 3-1
Figure 3-3 Figure 3-2Fuel SystemCheck Fuel System Pressure3-15the fuel pump, pressure regulator, and injector, and replace if necessary.
(7) After shutting down the engine, check the fuel pressure and
keep the specified pressure for about 5 minutes. The fuel pressure is:
147KPa.
3. The fuel oil pressure regulator (DR) (see Figure 3-3).
Mounting position: On the distributing pipe for fuel.
Faults: Too low or too high fuel pressure, or hard to start.
General causes: Using poor fuel for a long time results in: 1.
strainer blocked; 2. serious leakage caused by particles and impurities.
Other reasons: Man-made mechanical damage, etc.
Maintenance precautions: During maintenance: 1. Never impact the diaphragm element with high pressure
gas; 2. Never clean it with aggressively corrosive liquid; 3. No distortion caused by external force.
Easy measuring method: For the system with oil return, connect a pressure gauge for the fuel on the suction
pipe, start the engine, and run at idle speed. Now, the fuel pressure in the engine should be about 260KPa; pull out
the vacuum pipe of the fuel pressure regulator, and the pressure should be 300KPa approximately.Battery

Section 5 Carbon Canister Replacement1. Check and replace the canister.
(1) Check for crack or damage on the canister visually (see Figure 3-13).
(2) Check the operation of the canister.
a. Plug the discharge port (see Figure 3-14).
b. Blow air (4.71KPa, 48kgf/cm2) into the absorption port when keeping the discharge port closed, and the
air should flow out from the exit port.
If the operation is unsatisfactory, replace the canister.
c.Blow air into the absorption port, the air should flow from other ports without any resistance.
If the operation is unsatisfactory, replace the canister.
(3) Clean the canister: Block the desorption port, blow air (4.71KPa, 48kgf/cm2) into the absorption port, and
the air should flow from the discharge port (see Figure 3-15).Fuel SystemCarbon Canister Replacement3-192. Canister control valve (TEV) (see Figure 3-16)
Mounting position: On the vacuum pipeline of the canister - suction manifold.
Faults: Bad idle speed, malfunction, etc.
General cause: Ingress of foreign materials into inside of the valve results in corrosion and Poor tightness.
Maintenance precautions: During maintenance:
1. Air flowing direction must conform to specifications;
2. If the control valve fails due to black particles in the valve body, and it is necessary to replace the control
valve, please check the condition of the canister;
3. Avoid liquid such as water and oil entering into the valve during maintaining as possible;
4. It is advisable to mount the canister control valve on the hose hanging in the air or fasten with soft rubber
to avoid transmission of solid borne noise.Figure 3-13Figure 3-15 Absorption port

2. Remove 3 bolts of the flexibility plate (engine side)
3. Remove starter and 2 cooling hoses.
4. Disconnect neutral switch connector and odometer sensor.
5. Loosen the drain screw under the housing to bleed ATF and tighten the drain screw with sealing glue when
assembling. Tightening torque is 29~35N.m
6. Loosen the locking bolt for select lever cable.
7. Remove Drive Shaft LH&RH, using plastic stopper in the oil sealing of differential.
8. Detach suspension bolts.
9. Separate transmission from engine after bolts between engine and transmission remove.II. Automatic Transmission Installation1. Check whether torque converter of the transmission is in the right position, the methods as follows:
Check whether the distance from 3 anchor point of torque converter to front contact face of the transmission
box A 28mm , If the space A<28 mm, try install again. The way to install is that left hand catch hold of the
central anchor column of the converter and make it in alignment with input shaft as near as possible, push the torque
converter in rotating way by right hand until it gets to the bottom to meet the requirement of A 28 mm. (See
figure 7-1 and 2)
2. Install Flexibility plate and central plate on the crankshaft end face with 6 bolts in the direction of Figure 2.
Tightening torque is 45~55 N.m. Turn the longer hole of the Flexibility plate to the lowest of the engine position
in order to connect torque converter.Section 2 Hydraulic Torque Converter and TransaxleAutomatic Transaxle Assembly Hydraulic Torque Converter and Transaxle3-30 -
Figure 7-3Automatic Transaxle Assembly Hydraulic Torque Converter and Transaxle3-31Figure 7-5 Figure 7-4Figure 7-1
Figure 7-23. Install transmission in the engine, its way like manual transmission. The torque converter cannot be allowed to
move in axial motion during operating (The dimension of A keeps constant). Install starter in the transmission
housing.
4. Connect Flexibility plate with torque converter, using 3 special bolts. The way is as follows. First, assemble one
bolt in the torque converter by the longer hole of the Flexibility plate, and then rotate engine belt pulley to install
the other bolts, finally use torque spanner to tighten the bolts. Tightening torque is 40~50N.m.
5. Install suspension bolt and drive shaft LH&RH, the assembling way like manual transmission.
6. Connect two cooling pipes as showed in the figure 7-3 with the corresponding pipe of transmission with clip.
7. Connect the cable between bracket of throttle and transmission actuator.
8. Throttle valve cable adjustment as follows:
First, use pliers to clip the hexangular position under throttle valve cable.Turn 60°~90°counterclockwise,
and lift throttle valve cable to make throttle valve cable adjustable move to top position, and then turn back
60°~90° clockwise, meanwhile, make it lock (See figure 7-4). Finally put accelerator pedal to end position.
When throttle valve makes "ka-ka" sound, the distance under the throttle valve should meet B=2~8mm. If not,
try again until the gap B=2~8mm under the throttle valve (see figure 7-5), if gap B=2-8mm, throttle valve cable
adjustment is finished.Central
