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 assemblyClip the protrusion part of fixing ring and move lock claw toward

26. Check gas leakage of exhaust system
22

Exhaust gas controlExhaust gas control systemOn-vehicle inspection1. 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.Exhaust gas control - Exhaust gas control system2. 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.23

Engine mechanismEngine assemblyInspection1. Check coolant.
2. Check engine oil.
3. Check battery.
4. Check air filter assembly.
5. Check spark plug [4G18-3705113].
6. Check drive belt [4G18-1307107].Hint: do not check belt tension, because automatic tensioner is applied.7. Check ignition timing.(a) Warm up engine.
(b) Connect timing lamp to engine.
(c) Check ignition timing at idle speed.
Ignition timing: before top dead center Note: when checking ignition timing, place
transmission at neutral position.
Hint: After run the engine for 5 seconds with rotating
speed of 1000-1300rpm, check the engine could
recover to idle running.8. Check engine idle speed.(a) Warm up engine and run it at idle speed.
(b) Read engine rotating number in data flow with diagnostic instrument.
(c) Check idle speed.
Idle speed: about 750-850rpm
Notes:When checking idle speed, place cooling fan at OFF position.Turn off all auxiliary devices and air conditioner.Engine mechanism - Engine assemblyK-line 26

9. Check compression pressure.(a) Warm up engine.
(b) Remove ignition coil.
(c) Remove spark plug.
(d) Check cylinder compression pressure.
(1) Install cylinder compression pressure gauge on spark plug hole.
(2) Wide open throttle.
(3) Measure the pressure during crankshaft rotating.
Notes:Ensure to use fully charged battery to make the rotating speed of engine reach or exceed 250rpm.When measuring other items, please repeat steps (1) to (3). Finish the measurement as soon as possible.
Compression pressure: 1080kPa
Min pressure: 1000kPa
Difference among cylinders: 100kPa
(4) If the compression pressure of one or more cylinders is too low, inject a small amount of engine oil
from spark plug hole into the cylinder with low pressure, and repeat steps (1) to (3) to check
pressure.If the pressure increases after engine oil is injected, the piston ring of this cylinder or the
cylinder has been worn or scratched.If the pressure is still too low, the valve may be stuck or not fully closed, or the cylinder head
gasket leaks.10. Check CO/HC.(a) Start engine.
(b) Keep the rotating speed of engine at 2500rpm for about 180 seconds.
(c) When the engine is idle running, insert the test bar of CO/HC gauge into exhaust pipe at least 40cm.
(d) Immediately check idle speed and CO/HC concentration at 2500rpm.
Hints:Finish test within 3 minutes.Perform the test under 2 analog states (idle speed and 2500rpm) according to measuring meth-
ods and sequences specified by Emission Regulations.
(e) If CO/HC concentration is not within specified value, perform trouble shooting according to the
following sequences.
(1) Check the function of oxygen sensor.
(2) See possible failure causes listed in the table below, and repair and correct if necessary.Engine mechanism - Engine assembly27

5. Turn crankshaft to cylinder 1 compression top dead
center position.(a) Turn crankshaft pulley to align its groove with “o” mark on
timing chain hood.
(b) Check dot marks on camshaft timing sprocket and VVT
timing sprocket, and they should be in a line on timing chain
hood surface as shown in the diagram.
Hint: if not, turn crankshaft for one circle again
and align the above marks.6. Check valve clearance.(a) Only check the valves shown in the diagram.
(1) Measure the clearance between valve tappet and cam-
shaft with plug gauge.
(2) Record valve clearance measuring value exceeding
specification, and this value will be used to determine
valve tappet thickness that needs change.
