General
Refer to the VRSCA Electrical Diagnostic Manual for information on the function and testing of the throttle position sensor (TP sensor).
Removal
1. Remove airbox and air filter. See 1.4 Airbox and air filter.
Caution! If airbox is not to be reinstalled immediately, cover throttle body intakes with tape to prevent contaminates/ objects from falling down the throttle bores. Do not use shop rags or objects that could damage te throttle body butterflies.
2. See Figure 9-4. Cover air intakes (3) to prevent debris from entering cylinders.
