FI
f. 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.
The slot is worn or broken
→
Replace the
throttle position sensor.
NOTE: NOTE:
Check mainly that the resistance changes
gradually when turning the throttle, since the
readings (from closed to wide-open throttle)
may differ slightly from those specified.
2. Adjust:
• throttle position sensor angle
a. Connect the throttle position sensor coupler
to the wire harness.
b. Connect the digital circuit tester to the throt-
tle position sensor.
c. Measure the throttle position sensor volt-
age.
d. Adjust the throttle position sensor angle so
the measured voltage is within the specified
range.
e. After adjusting the throttle position sensor
angle, tighten the throttle position sensor
screws.
