Understanding Electronic Throttle Bodies

VIDEO: Understanding Electronic Throttle Bodies

A failing ETB can lead to decreased power, poor fuel economy and poor drivability.

The throttle body is a valve that controls the amount of air that goes into the engine for combustion. 

For decades, the throttle was operated by a cable or mechanical linkage – that is until the late 1980s, when the electronic throttle body emerged. Since the early 2000s, adoption of electronic throttle bodies has been steadily rising, and today they’re installed on nearly every new vehicle when they roll off the assembly line.

What Are Direct Ignition Coils?

The stick coil eliminates ignition wires and utilizes wasted space by fitting neatly into the spark plug bore.

Ignition coils transform battery voltage into the higher voltage needed to jump the spark plug gap and efficiently ignite the air-fuel mixture in an engine.

Direct ignition coils are by far the most common type of ignition coil found in modern direct ignition systems, and they’ve been adopted by most of the major automakers. In this design, the coil mounts directly on top of the spark plug, eliminating the need for an ignition wire.
