d. While slowly opening the throttle, check
that the throttle position sensor resistance
is within the specified range.
The resistance does not change or it
changes abruptly → Replace the throttle
position sensor.

3. Install:
• Throttle position sensor
NOTE:
When installing the throttle position sensor,
adjust its angle properly. Refer to "ADJUST-
ING THE THROTTLE POSITION SENSOR"
on page 7-7.

CHECKING THE SUB-THROTTLE POSITION
SENSOR
1. Remove:
• Sub-throttle position sensor
(from the throttle body)
2. Check:
• Sub-throttle position sensor

a. Disconnect the sub-throttle motor coupler.
b. Disconnect the sub-throttle position sensor
coupler.
c. Remove the sub-throttle position sensor
from the sub-throttle servo motor.
d. Connect the pocket tester (Ω × 1k) to the
sub-throttle position sensor as shown.

ELECTRICAL COMPONENTS
• Tester positive lead →
Blue "1"
• Tester negative lead →
Black/Blue "2"
e. Check the throttle position sensor maxi-
mum resistance.
Out of specification → Replace the throttle
position sensor.
Maximum sub-throttle position
sensor resistance
4–6 kΩ at 20 °C (68 °F)
f. Connect the pocket tester (Ω × 1k) to the
throttle position sensor as shown.
• Tester positive lead →
Green/Yellow "3"
• Tester negative lead →
Black/Blue "2"
g. While slowly opening the sub-throttle worm
nut, check that the sub-throttle position
sensor resistance is within the specified
range.
The resistance does not change or it
changes abruptly → Replace the sub-throt-
tle position sensor.
NOTE:
Check mainly that the resistance changes
gradually when turning the sub-throttle worm
nut, since the readings (from closed to wide-
open sub-throttle) may differ slightly from those
specified.
