TROUBLESHOOTING
When troubleshooting to determine the cause of start-
ing or running problems, the technician should use dis-
cretion and sound judgment.
1. Make sure there is sufficient, clean gasoline in the
gas tank.
2. Verify the battery is sufficiently charged to crank
the engine over at normal speed. EFI systems are
extremely sensitive to voltage.
3. Check for a flashing or steady Malfunction Indica-
tor Light (MIL) on the LCD along with the mal-
function code.
NOTE: The MIL is a small wrench icon, and the
codes are four digits preceded by a letter C (chas-
sis) or P (power train).
4. Check the air filter and air intake system for con-
tamination or restrictions. Clean or repair as nec-
essary (see Section 2).
5. Verify the electric fuel pump is operating by listen-
ing for a momentary “whirring” sound when the
ignition switch is turned to the ON position. If no
sound is heard, refer to Power Distribution Mod-
ule (PDM) in Section 5 or Electric Fuel Pump/Fuel
Level Sensor in this section.
Throttle Body
The throttle body houses several EFI components
including the throttle valve, Inlet Air Tempera-
ture/Manifold Absolute Pressure sensor (IAT/MAP),
Idle Speed Control (ISC) valve, and Throttle Position
Sensor (TPS). The fuel injector is housed in the intake
pipe attached to the cylinder head. The components
housed in the throttle body are easily replaced with the
throttle body removed.
REMOVING
1. Turn the ignition switch to the OFF position; then
remove the ignition switch key.
2. Remove the seat.
3. Remove the storage compartment cover and stor-
age compartment.
4. Loosen the clamps securing the air inlet to the
throttle body and air filter housing; then remove
the air inlet pipe.
5. Loosen the clamp securing the air filter housing to
the front air inlet duct; then disconnect the coil and
remove the spark plug cap from the spark plug.

6. Pull the air filter housing assembly to the rear and
disconnect the crankcase breather hose from the
housing; then remove from the ATV.
