Throttle Sensor Inspection
○
If the variable rheostat is not available, refer to throttle
sensor output/input voltage check in the C.D.I. Unit in-
spection.
○
When inspecting the throttle sensor the throttle valve of
the carburetor shall be completely closed and remain
the throttle cable connected.
•
Remove the carburetor (see Carburetor Removal in the
Fuel System chapter).
•
Connect the throttle sensor lead connector [A] with the
battery [B], variable rheostat [C] and hand testers [D] as
shown.
Variable Rheostat (+) → Blue Lead Terminal [E]
Hand Tester (+) → Yellow Lead terminal [F]
Hand Tester (–) → Black Lead terminal [G]
•
Check the sensor input voltage.
Throttle Sensor Input Voltage
Standard:
•
Check the sensor output voltage with the throttle valve is
completely closed.
Throttle Sensor Output Voltage
Standard:
0.68 ±0.1 V (when the engine speed is
idle.)
If it is not within the specified voltage, adjust the throt-
tle sensor position (see Throttle Sensor Position Adjust-
ment).
If it is within specified voltage, go to next test.
•
Check the sensor output voltage with the throttle fully
opened.
Throttle sensor Output Voltage
3.5 ∼ 3.7 V (When throttle fully opened.)
Standard:
If it is not within the specified voltage, replace the sensor.
NOTE
around 5 V
