Throttle Sensor Output/Input Voltage Check: (KX250)

If the variable rheostat is available, refer to throttle sen-
sor inspection.
Remove the carburetor lead connector.
Connect the auxiliary leads [A] between carburetor lead
connector [B] and main harness connector [C].
Set the tester to the DC 10V range, and connect it to the
auxiliary leads.
Special Tool - Hand Tester: 57001-1394
Hand Tester (+) → Red/Green Lead
Hand Tester (–) → Black/Green Lead
Start the engine.
Check the sensor input voltage with the engine running.
Throttle Sensor Input Voltage
Standard:
4 V or above
If it is not within the specified voltage range, check the
magneto output voltage. If it has normal functions, re-
place the C.D.I. Unit.
To check the output voltage, do the following procedures.
Using the auxiliary leads [A], connect the hand tester [B]
as follows.
Hand Tester (+) → White/Black Lead
Hand Tester (–) → Black/Green Lead
Remove the spark plug.
Crank the engine by kicking the pedal several times to
measure the throttle sensor output voltage with the throt-
tle valve completely closed.
Throttle Sensor Output Voltage
0.4 ∼ 0.6 V (when throttle valve is
Standard:
completely closed.)
If it is not within the specified voltage range, adjust the
throttle sensor position (see Throttle Sensor Position Ad-
justment).
If it is within specified voltage, go to next test.
Crank the engine by kicking the pedal several times to
measure the throttle sensor output voltage with the throt-
tle fully opened.
Throttle Sensor Output Voltage
(when the throttle fully opened)
3.5 ∼ 3.7 V
Standard:
If it is not within the specified voltage, replace the throttle
sensor.

Engine Stop Switch Electric Current Check:

Disconnect the engine stop switch lead.
Start the engine.
Ground the stop switch lead of the main harness side
while the engine is running.
If does not stop the engine, replace the C.D.I Unit.
