SPARK PLUG CHECK AND CLEANING
<4G1>
M1163004300342
CAUTION
When pulling off the spark plug cable from the
plug always hold the cable cap, not the cable.
1. Remove the spark plug cables.
2. Remove the spark plugs.
3. Check for burned out electrode or damaged insulator. Check for even burning.
4. Remove carbon deposits with wire brush or plug cleaner. Remove sand from plug screw with
compressed air.

5. Use a plug gap gauge to check that the plug gap is within the standard value range.
Standard value: 1.0 − 1.1 mm
If the plug gap is not within the standard value
range, adjust by bending the earth electrode.
CAUTION
Be careful not to allow foreign matter in cylin-
ders.
6. Clean the engine plug holes.
7. Install the spark plugs.

1. When connecting the vacuum hoses, they should
be securely inserted onto the nipples.
2. Connect the hoses correctly, using the vacuum hose piping diagram as a guide.
CRANKCASE EMISSION CONTROL
SYSTEM
GENERAL INFORM ATION (CRANKCASE
EMISSION CONTROL SYSTEM)
M1173005000237
The crankcase emission control system prevents
blow-by gases from escaping inside the crankcase
into the atmosphere.
Fresh air is sent from the air cleaner into the crank-
case through the breather hose.
The air becomes mixed wi th the blow-by gases
inside the crankcase.
The blow-by gas inside the crankcase is drawn into
the intake manifold through the positive crankcase
ventilation (PCV) valve.
The PCV valve lifts the plunger according to the
intake manifold vacuum so as to regulate the flow of
blow-by gas properly.
In other words, the blow-by gas flow is regulated dur-
ing low load engine operation to maintain engine sta-
bility, while the flow is increased during high load
operation to improve the ventilation performance.

EXHAUST GAS RECIRCULA
T ION
(EGR) SYSTEM
GENERAL INFORMAT ION (EGR SYSTEM)
M1173 0052 0032 7
The exhaust gas recircu l atio n (EGR) system lowers
the nitrogen
oxide (NOx) emission level.
When the air/fuel mixture combus tio n temp erature is
high,
a larg e qua ntity of nitrogen oxides (NOx) is
generat
ed in the comb ustion chamb e r .
Therefor e, this syst em re circulat es p a rt o f emission
gas fro
m the e x ha ust po rt of the cylinder h ead to th e
combust
i on chamber thro ugh th e int a ke ma nifold to
decre
ase the air/fuel mixture combust i on te mpera
-
ture, resulting in redu ctio n of NOx.
The EGR flow rate is cont rolle d by the EGR valve so
as no
t to de crease the driveability .
OPERAT ION
The EGR valve is being clos ed an d does not re circu-
late ex hau st ga ses unde r one o f the fo llo wing condi-
tions.
Otherwise, th e EGR va lve is opene d an d recircul ates

•The engine coolan t temperature is low .
•The engine is at idle.
•The throttle va lve is widely ope ned.
