Speed Sensor - Arctic Cat WILDCAT X Service Manual

SPEED SENSOR

Component data can be retrieved using the CATT II. Uti-
lize the Sensor Data screen.

NOTE: Preliminary checks may be performed on
this component using the diagnostic mode on the LCD
gauge (see EFI Diagnostic System in this section).

NOTE: Prior to testing the speed sensor, inspect the
three-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 orange wire; then
connect the black tester lead to the black wire.
3. Turn the ignition switch to the ON position.
4. The meter must show battery voltage.
5. Leave the black tester lead connected; then connect
the red tester lead to the pink/white wire.
6. Slowly move the vehicle forward or backward; the
meter must alternate between 0 and battery voltage.
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.

FUEL PUMP/FUEL LEVEL SENSOR

NOTE: Preliminary checks may be performed on
this component using the diagnostic mode on the LCD
gauge (see EFI Diagnostic System in the Electrical
System section).
The fuel pump and fuel level sensor are not serviceable
components. If either component fails, it must be
replaced.
Testing
! WARNING
Whenever any maintenance or inspection is made on
the fuel system during which there may be fuel leakage,
there should be no welding, smoking, open flames, etc.,
in the area.
AT THIS POINT

Prior to removing the fuel pump, the following test
should be performed to determine that removal is nec-
essary.
1. Turn the ignition switch ON and listen for a momen-
tary "whirring" sound of the pump building pressure.
If the sound is heard (10 seconds), no electrical
checks are necessary. Turn the ignition switch OFF.
2. Disconnect the gasline hose from the fuel rail; then
install a suitable pressure gauge.
! WARNING
Gasoline may be under pressure. Place an absorbent
towel under the connector to absorb any gasoline spray
when disconnecting.

3. Turn the ignition switch to the ON position. The fuel
pressure should build until the pump shuts off. Pres-
sure should read 3.0 kg-cm
2
(43 psi).
