e. Check the throttle position sensor maxi-
mum resistance.
Out of specification → Replace the throttle
position sensor.
f. Connect the pocket tester (Ω × 1k) to the
throttle position sensor as shown.
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.

3. Install:
• Sub-throttle position sensor
NOTE:
When installing the throttle position sensor,
adjust its angle properly. Refer to "ADJUST-
ING THE SUB-THROTTLE POSITION SEN-
SOR" on page 7-9.
