The combustion of an engine relies on the engine maintaining the correct ratios of oxygen to fuel. For an engine to run efficiently and effectively, it needs both an air-intake system to bring in outside air, as well as a fuel pump to pump in gas from the gas tank. There are a number of parts in the air-intake system, one of which is called the "throttle body." The throttle body has a valve that opens or closes, which regulated the amount of air that is being put into the engine.

A schematic is a type of technical drawing that displays the parts of a piece of equipment. In this case, a throttle body schematic would display all parts of the throttle body in the correct placement, such as the valve, the chamber, the various seals and the moving parts. A schematic helps individuals to understand how the throttle body is put together, both mechanically and electronically.
