APP Sensor Assembly InspectionS7RS0B1306007
Check APP sensor (main and sub) output voltage as
following steps.
1) For APP sensor (main) , arrange 3 new 1.5 V
batteries (1) in series (check that total voltage is 4.5 -
5.0 V) and connect its positive terminal to “Vin 1”
terminal (2) and negative terminal to “Ground 1”
terminal (3) of sensor. Then using voltmeter, connect
positive terminal to “Vout 1” terminal (4) of sensor
and negative terminal to battery.
2) For APP sensor (s ub), arrange 3 new 1.5 V batteries
(1) in series (check that total voltage is 4.5 - 5.0 V)
and connect its positive terminal to “Vin 2” terminal
(2) and negative terminal to “Ground 2” terminal (3)
of sensor. Then using volt meter, connect positive
terminal to “Vout 2” terminal (4) of sensor and
negative termin al to battery.
3) Measure output voltage variation while accelerator pedal is no depressed and fully depressed as
following specification.
If sensor voltage is out of specified value or does not
vary linearly as the followin g graph, replace APP sensor
assembly.
APP sensor output voltage
APP sensor (main) output voltage [A]: 0.75 – 3.85 V,
varying according to depressed extent of
accelerator pedal
APP sensor (sub) output voltage [B]: 1.55 – 4.65 V,
varying according to depressed extent of
accelerator pedal.
ECT Sensor Removal and InstallationS7RS0B1306008
Removal
1) Disconnect negative (–) cable at battery.
2) Drain coolant referring to “Cooling System Draining in Section 1F”.

Check each valve for radial runout with a dial gauge and
“V” block. To check runout, rotate valve slowly. If runout
exceeds its limit, replace valve.
Valve head radial runout
Limit: 0.08 mm (0.003 in.)
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.
Standard seating width “a” revealed by contact
pattern on valve face

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.
Seat width for exhaust valve seat

2) Intake valve seat:
Use valve seat cutters (1) to make three cuts as
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.
Seat width for intake valve seat
“b”: 1.0 – 1.4 mm (0.0389 – 0.0551 in.)

Cooling System Flush and RefillS7RS0B1606005
WARNING!
To help avoid danger of being burned, do not
remove radiator cap while engine and
radiator are still hot. Scalding fluid and steam
can be blown out under pressure if cap is
taken off too soon.

NOTE
For detail of coolant specification, refer to
“Coolant Description”.

1) Remove radiator cap when engine is cool as follows.a) Turn cap counterclockwise slowly until it reaches a “stop” (Do not press down while turning it).
b) Wait until pressure is relieved (indicated by a hissing sound) then press down on cap and
continue to turn it counterclockwise.
2) With radiator cap removed, run engine until upper radiator hose is hot (this shows that thermostat is
open and coolant is flowing through system).
3) Stop engine and drain coolant from radiator drain plug (1).
4) Close radiator drain plug. Add water until system is filled and run engine until up per radiator hose is hot
again.
5) Repeat Steps 3) and 4) several times until drained liquid is nearly colorless.
6) Close radiator drain plug (1) tightly. 7) Remove reservoir (1) and remove cap (2) from
reservoir (1).
8) Pour out any fluid, scrub and clean inside of reservoir with soap and water.
Flush it well with clean water and drain, Reinstall
reservoir.
9) Fill reservoir with coolant up to “Full” level mark (3).
10) Install reservoir cap (2) on reservoir. 11) Fill radiator with coolant up to bottom of radiator filler neck and install radiator cap, making sure that the
ear of cap lines is parallel to radiator.
12) Run engine at idle speed.
13) Run engine until radiator fan motor is operated.
14) Stop engine and wait until engine comes cooled down to help avoid danger of being burned.
15) Add coolant to radiator up to bottom of radiator filler
neck, and install radiator ca p, making sure that the
ear of cap lines is parallel to radiator.
16) Repeat Step 12) through 15).
17) Confirm that reservoir cool ant level is “Full” level
mark (3). If coolant is insu fficient, repeat Step 9) and
10).
Cooling Water Pipes or Hoses Removal and
Installation
S7RS0B1606006
Removal
1) Drain coolant referring to “Cooling System Draining”.
2) To remove these pipes or hoses, loosen clamp on each hose and pull hose end off.
Installation
Install removed parts in reverse order of removal
procedure, noting the following.
• Tighten each clamp securely referring to “Cooling System Components”.
• Refill cooling system referrin g to Step 7) to 22) of

With Charging Equipment
CAUTION!
When jump starting engine with charging
equipment, be sure equipment used is 12-
volt and negative ground. Do not use 24-volt
charging equipment. Using such equipment
can cause serious damage to electrical
system or electronic parts.

Battery Dismounting and RemountingS7RS0B1A06002
WARNING!
When handling battery, following safety
precautions should be followed:
• Hydrogen gas is produced by battery. A flame or spark near battery may cause the
gas to ignite.
• Battery fluid is highly acidic. Avoid spilling on clothing or other fabric. Any spilled
electrolyte should be flushed with large
quantity of water and cleaned immediately.

Dismounting
1) Disconnect negative cable (1).
2) Disconnect positive cable (2).
3) Remove retainer (3).
4) Remove battery (4).
Remounting 1) Reverse removal procedure.
2) Tighten battery cables securely.

Inspection and Adjustment
S7RS0B1A06003
WARNING!
Disconnect negative cable at battery before
checking and adjusting belt tension.

1) Inspect belt for cranks, cuts, deformation, wear and clealiness. If it is necessary to replace belt, refer to
“Water Pump / Generator Drive Belt Removal and
Installation”.
2) Check belt for tension. Belt is in proper tension when it deflects the following specification under thumb
pressure (about 10 kg or 22 lb.).
If belt tension is out of spec ification, go to next steps.

CAUTION!
Be sure to set front wheels (tires) in straight
direction and remove ignition key from key
cylinder before performing the following
steps; otherwise, contact coil of air bag
system may get damaged.

1) Remove steering joint cover.
2) Make alignment marks (1) on pinion shaft (2) and joint of steering lower shaft (3) for a guide during
