Section 4 Fuel Emission Control SystemOn-board Inspection1. Check the operation when disconnecting the fuel supply.
(1) Warm the engine up to 2,500r/min at least, and check the noise of the injector with a sound level meter
(see Figure 3-9).
(2) When the throttle releases, the noise from the injector should stop immediately; repeat several times.
2. Check the fuel vapor discharge control system (see Figure 3-10).
(1) After starting the engine, disconnect the vacuum pipe.
(2) Make sure that there is vacuum present at the canister control valve (TEV) port when selecting ”ACTIVE
TEST" and "PURGE TEV" based on the display on the fault diagnosis instrument.
(3) After "ACTIVE TEST", connect the vacuum pipe.
(4) Carry out "ECM DATA MONITOR" on the fault diagnosis instrument, and then select "PURGE TEV"
for operation inspection.
(5) Start up the car after the engine warms up, and make sure the TEV ON from OFF (see Figure 3-11).
3. Check whether there is any distortion or damage on the filling cap and the washer (see Figure 3-12).Figure 3-9 Figure 3-10Fuel SystemFuel Emission Control System3-18Figure 3-11 Figure 3-12Sound level meter

3. Vent valve (PCV) sub-assembly
Air should flow through the cylinder cap side freely.
Attention:

Do not suction air through the valve.
Never put anything into the valve. If the operation is unsatisfactory, replace PCV.

Blow air into from the suction side, and the air should be hard to flow through. If the operation is
unsatisfactory, replace PCV (see Figure 3-17).Figure 3-17Fuel SystemCarbon Canister Replacement3-20Figure 3-16 Easy measuring method: (disconnect the connector) Set the digital multi-meter to ohm position, with two leads
connecting to two pins of the canister control valve respectively, rated resistance 22-30 ohm at 20°CEasy HardCylinder head sideManifold side

troubleshot step by step in the section of the malfunction diagnosis.Tester connection Conditions Standard condition
C 12- ground Turn ignition switch to ON position 10-14 VCombination Instrument System -Malfunction Symptom Table and Troubleshooting5-10II. Specific troubleshooting steps The entire combination instrument does not work (1) Check safety wire (refer to schematic diagram of
combination instrument)
a. Check GAUGE (10 A) safety wire in fuse box of instrument desk is on
b. Check AM 1 (30 A) safety wire in fuse box of engine room is on
c. Check MAIN (80 A) safety wire in fuse box is on
Result and measures: if there is any blowout, replace with a safety wire of the same capacity
(2) Check team whole instrument socket connector
a. Inspect continuity
Disconnect connector from combination instrument assy.
Check connection between terminals
Standard:
b. Check voltage
Disconnect connector from combination instrument assy.
Turn ignition switch to ON
Check voltage between terminals
Standard:

5-73Precautions:1. Don't operate refrigerant in confined space or near open fire.
2. Always wear eyeglass.
3. Be careful don't let liquid refrigerant contact your eyes and skin,
if liquid refrigerant contacts your eye or skin.
(a) Please wash with fresh water.
Warning:
Don't knead your eyes or scrub your skin
(b) Apply soft petroleum ointment on your skin.
(c) See doctor or go to hospital immediately for specialized
treatment.
4. Don't heat container or put it near open fire.
5. Be careful not to fall off, object should not touch container.
6. If there is no sufficient refrigerant in refrigerating system, don't
operate the compressor.
If there is no sufficient refrigerant in the system, insufficient oil
lubrication might cause burning out of compressor. Be careful to
avoid occurrence of such things.
7. When compressor runs, don't turn on pressure gauge high-pressure
valve.
If high-pressure valve is turned on, refrigerant will flow in reverse
direction, and cause bursting of refrigerant tank, so only low
pressure valve may be turned on or off.
8. Be careful to avoid excess refrigerant
Excess refrigerant will result in poor refrigerating capacity, worse
fuel economical efficiency, engine overheat etc problems.Symptom
Blower does not workSymptom table Use the following table to find out the cause of fault, number indicates probable priority of problem, check each
part according to priority, replace components if required.

Fault symptom
Flameout, poor idle speedChapter 9 Engine EFI SystemI. Outline This system includes sensor that detects engine functioning. Engine ECU utilizes sensors installed at differ-
ent parts of engine to measure various working parameters of engine, accurately control oil injection quantity
according to control procedure set in engine electronic control unit, so engine could work in optimum mode
under various operating conditions, i. e. optimal power output, the most economical oil consumption, optimal
exhaust emissions. Engine ECU is capable of start up control, idle speed closed-loop control, air fuel ratio
closed-loop control, canister control, transient operation control, angle of ignition control, knocking control, air
conditioning control, coasting fuel cutoff and overspeed fuel cutoff control, ternary catalyst heating and protec-
tion control, system self-diagnosis etc.II. Inspection of control element1. Manifold intake pressure temperature sensor
(1) The part to measure intake pressure is piezo type sensor, could provide controller with "load signal "
according to the difference between atmospheric pressure and manifold pressure; controller will supply 5V
voltage, and feed back 0-5V voltage to controller according to different intake pressures. The part to measure
intake temperature is NTC type (negative temperature coefficient) sensor, resistance changes with intake
temperature, this sensor conveys a voltage representing intake temperature change to the controller.
(2) Simple measuring method:
Temperature sensor part: (remove joint) turn digital multimeter
to Ohm position, two meter pens connect sensor 1 #, 2 # pinrespectively, rated resistance is 2. 5k ohm±5% at 20°C, correspond-ing resistance value may be measured from the above characteristic
curve. Simulation method may also be used for measurement, spe-
cific procedure is to use electric drier to blast sensor (pay attention not
to be too close), observe change of sensor resistance, here resistanceEngine EFI System-Engine EFI System5-120Possible cause
There is abnormal high voltage or reverse heavy current during useVacuum
unit is damaged during repair
Repair precautions: it is prohibit to use high pressure gas to impact vacuum unit during repair; when replace
sensor case of trouble, check whether generator output voltage and current is normal or not.1 2 3 4Manifold intake pressure temperature
