A
THROTTLE BODIES
b. After performing the step a, move the sub-
throttle position sensor to adjust to be in a
range from 0.97 to 1.07 V
Sub-throttle position sensor
voltage
0.97 X 1.07 V
(green/yellow – blue)
NOTE:
S After setting up the sub-throttle position sen-
sor, check that the sub-throttle position sensor
output voltage is 0.4 V or more with the nut of
worm shaft turned to the full close side until it
stops.
S When the sub-throttle position sensor output
voltage is 0.4 V or more, check that the sub-
throttle position sensor output voltage is 4.6 V
or less with the nut of worm shaft turned to the
full open side until it stops.
CHECKING AND ADJUSTING THE THERMO
WAX
1. Check:
S thermo wax 1
Damege ! Replace the thermo wax.
2. Adjust:
S thermo wax the end face distance a
a. Before adjusting the distance, push the rod
b in order to be fitted in several times by
hand.
b. Measure the outside air temperature, and
adjust the distance a by turning the adjust-
ing screw 2 . Refer to the thermo wax toler-
ance table based on the measured outside
air temperature for correct adjustment.
NOTE:
S Setup tolerance of the longitudinal axis should
be " 0.2 mm (" 0.008 in).
S After adjusting the thermo wax, check that the
first idling is released at the coolant tempera-
ture around 60_C (140_F) by idling.
S If the first idling is not released around 60_C
(140_F), make sure to set it again. (When the
coolant temperature is low, adjust the distance
between the end faces longer or adjust it short-
er when the coolant temperature is high.)
S In case of turning the adjusting bolt two-third
turn, the temperature varies about 10_C
(50_F).
