Speed Sensor
NOTE: Prior to testing the speed sensor, inspect the
four-wire connector on the speed sensor for contami-
nation, broken pins, and/or corrosion.
1. Set the meter selector to the DC Voltage position.
2. With appropriate needle adapters on the meter leads,
connect the red tester lead to the voltage lead (V); then
connect the black tester lead to the ground lead (G).

3. Turn the ignition switch to the ON position.
4. The meter must show 6-12 DC volts.
5. Leave the black tester lead connected; then connect
the red tester lead to the signal lead (S) pin.
6. Slowly move the ATV forward or backward; the
meter must show 0 and 6-12 DC volts alternately.
NOTE: If the sensor tests are within specifications,
the LCD gauge must be replaced (see Steer-
ing/Frame/Controls).
To replace a speed sensor, use the following procedure.
1. Disconnect the three-wire connector from the speed
sensor harness or from the speed sensor; then remove
the Allen-head cap screw securing the sensor to the
sensor housing.
2. Remove the sensor from the sensor housing account-
ing for an O-ring.
3. Install the new speed sensor into the housing with new
O-ring lightly coated with multi-purpose grease; then
secure the sensor with the Allen-head cap screw (threads
coated with blue Loctite #242). Tighten securely.

RPM Limiter
NOTE: The ATV is equipped with an ECM that cuts fuel spray and spark when maximum RPM is approached.
When the RPM limiter is activated, it could be misinterpreted as a high-speed misfire.
Component data can be retrieved using the CATT II. Uti-
lize the Sensor Data screen.
