Electronic Throttle Body Operation and Failure Issues
This is a video on how the electronically control throttle body works. Also, some of the common parts that fail and how they fail.
This specific throttle body is off a 2005 Volvo S60
A DC motor drives a toothed plastic gear, that in turn drives the throttle plate gear. A potentiometer sits on the throttle gear and returns signals to the computer through the sweeps on TB cover.
Common failures are the swept area of the potentiometer getting wear marks in them, the sweeper arms breaking down, and the plastic teeth breaking or wearing off of the gears.
