There are two kinds of colored wire used in this vehicle. One is single-colored wire and the other is dual-colored 
(striped) wire.
The single-colored wire uses only one color symbol (i.e. “GRN”).
The dual-colored wire uses two color sy mbols (i.e. “GRN/YEL”). The first symbo l represents the base color of the wire 
(“GRN” in the figure) and the second symbol represents  the color of the stripe (“YEL” in the figure).
Fasteners InformationS7RS0B0101004
Metric Fasteners
Most of the fasteners used for this vehicle are JIS-
defined and ISO-defined metric fasteners. When 
replacing any fasteners, it is most important that 
replacement fasteners be the correct diameter, thread 
pitch and strength.
CAUTION! 
Even when the nominal diameter (1) of thread 
is the same, the thread pitch (2) or the width 
across flats (3) may vary between ISO and 
JIS. Refer to JIS-TO-ISO Main Fasteners 
Comparison Table below for the difference.
Installing a mismatched bolt or nut will cause 
damage to the thread.
Before installing, check the thread pitch for 
correct matching and then tighten it by hand 
temporarily. If it is tight, recheck the thread 
pitch.
 
JIS-TO-ISO Main Fasteners Comparison Table Fastener Strength Identification
Most commonly used metric fastener strength property 
classes are 4T, 6.8, 7T, 8.8 and radial line with the class 
identification embossed on the head of each bolt. Some 
metric nuts will be marked with punch, 6 or 8 mark 
strength identification on the nut face. Figure shows the 
different strength markings.
When replacing metric fasteners, be careful to use bolts 
and nuts of the same strength or greater than the original 
fasteners (the same number marking or higher). It is 
likewise important to select replacement fasteners of the 
correct diameter and thread 
pitch. Correct replacement 
bolts and nuts are available through the parts division.
Metric bolts: Identification class numbers or marks 
correspond to bolt strength (increasing numbers 
represent increasing strength).

Scan Tool DataS7RS0B1104007
As the data values are standard values estimated on the basis of values obtained from the normally operating vehicles 
by using a scan tool, use them as re ference values. Even when the vehicle is  in good condition, there may be cases 
where the checked value does not fall within each specified  data range. Therefore, judgment as abnormal should not 
be made by checking with these data alone.
Also, conditions that can be checked by  the scan tool are those detected by ECM and output from ECM as commands 
and there may be cases where the engine or actuator is not operating (in the condition) as indicated by the scan tool. 
Be sure to use the timing light  to check the ignition timing.
NOTE
• There are two types of OBD system depending on the vehicle specification.
For details, refer to “Precaution on  On-Board Diagnostic (OBD) System”.
• With the generic scan tool, only star (*) marked data in the following table can be read.
• When checking the data with the engine running at idle or racing, be sure to shift M/T gear to the  neutral position and A/T gear to the “Park” position  and pull the parking brake fully. Also, if nothing 
or “no load” is indicated, turn O FF A/C (if equipped with A/C), all electric loads, P/S and all the other 
necessary switches.

Scan Tool Data Definitions
COOLANT TEMP (ENGINE COOLANT 
TEMPERATURE, °C,  °F)
It is detected by engine coolant temp. sensor.
INTAKE AIR TEMP. ( °C,  °F)
It is detected by intake air temp. sensor.
ENGINE SPEED (rpm)
It is computed by reference pulses from the camshaft 
position sensor.
INJ PULSE WIDTH (FUEL INJECTION PULSE WIDTH, 
msec.)
This parameter indicates time of the injector drive (valve 
opening) pulse which is output from ECM (but injector 
drive time of NO.1 cylinder fo r multiport fuel injection).
DESIRED IDLE (DESIRED IDLE SPEED, rpm)
The Desired Idle Speed is  an ECM internal parameter 
which indicates the ECM requested idle. If the engine is 
not running, this number is not valid.
SHORT FT B1 (SHORT TERM FUEL TRIM, %)
Short term fuel trim valu e represents short term 
corrections to the air/fuel  mixture computation. A value 
of 0 indicates no correction, a value greater than 0 
means an enrichment correction, and a value less than 0 
implies an enleanment correction. LONG FT B1 (LONG TERM FUEL TRIM, %)
Long term fuel trim value represents long term 
corrections to the air/fuel mixture computation. A value 
of 0 indicates no correction, a value greater than 0 
means an enrichment correction, and a value less than 0 
implies an enleanment correction.
TOTAL FUEL TRIM B1 (%)
The value of Total Fuel Trim is obtained by calculating 
based on values of Short Term Fuel Trim and Long Term 
Fuel Trim. This value indica
tes how much correction is 
necessary to keep the air/fuel mixture stoichiometrical.
MAF (MASS AIR FLOW RATE, g/s, lb/min.)
It represents total mass of air entering intake manifold 
which is measured by mass air flow sensor.
CALC LOAD (CALCULATED LOAD VALUE, %)
Engine load displayed as a percentage of maximum 
possible load. Value is calculated mathematically using 
the formula: actual (current) intake air volume  ÷ 
maximum possible intake air volume  × 100%
THROTTLE POS (ABSOLUTE THROTTLE POSITION, 
%)
When throttle position sensor is  at fully closed position, 
throttle opening is indicated as 0 – 5% and 90 – 100% 
full open position.
O2S SENSOR B1 S1 (HEA TED OXYGEN SENSOR-1,

It indicates output voltage of HO2S-1 installed on 
exhaust manifold (pre-catalyst).

Seating contact width
Create contact pattern on each valve in the usual 
manner, i.e., by giving uniform coat of marking 
compound to valve seat and by rotatingly tapping seat 
with valve head. Valve lapper (tool used in valve lapping) 
must be used. 
Pattern produced on seating face of valve must be a 
continuous ring without any break, and the width of 
pattern must be within specified range.

A valve seat not producing 
a uniform contact with its 
valve or showing width of seating contact that is out of 
specified range must be repaired by regrinding or by 
cutting and regrinding and finished by lapping.
1) Exhaust valve seat:
Use valve seat cutters (1 ) to make two cuts as 
illustrated in the figure.  Two cutters must be used: 
the first for making 22 ° angle, and the second for 
making 45 ° angle. The second cut must be made to 
produce desired seat width.

illustrated in the figure. Th ree cutters must be used: 
the 1st for making 22 ° angle, the 2nd for making 60 ° 
angle, and 3rd for making 45 ° angle. The 3rd cut 
(45 °) must be made to produce desired seat width.

with fine-size compound, each time using valve 
lapper according to usual lapping method.

2) Install bearing in connecting rod and bearing cap.
3) Place a piece of gauging plastic (1) to full width of  crank pin as contacted by bearing (parallel to 
crankshaft), avoiding oil hole.
4) Install rod bearing cap (1) to connecting rod. When installing cap, be sure  to point arrow mark (2) 
on cap to crankshaft pulley side, as shown in figure. 
After applying engine oil to bearing cap bolts (3), 
tighten bearing cap bolts (3) gradually as follows. 
a) Tighten all bearing cap bolts to 15 N ⋅m (1.5 kgf-

bearing and recheck clearance or regrind crank pin 
to undersize and use 0.25 mm undersize bearing.
Selection of Connecting Rod Bearings
NOTE
• If bearing is in malcondition, or bearing  clearance is out of specification, select a 
new standard bearing according to the 
following procedure and install it.
• When replacing crankshaft or connecting  rod and its bearing due to any reason, 
select new standard bearings to be 
installed by referring to numbers stamped 
on connecting rod and its cap and/or 
alphabets stamped on crank web of No.3 
cylinder.
 
1) Check stamped numbers on connecting rod and its  cap as shown.
Three kinds of numbers (“1”, “2” and “3”) represent 
the following connecting rod big end inside 
diameters.
For example, stamped number “1” indicates that 
corresponding connecting rod big end inside 
diameter is 45.000 – 45.006 mm (1.7717 – 1.7718 
in.).
