Volvos affected by the electronic throttle module (“ETM”) are 1999-2002 models (US model years). Before 1999, Volvo used a good old mechanical set of parts to control the throttle. In 1999, they switched to a “fly-by-wire” module… this problematic ETM.
Volvo’s 1999-2002 ETM fails because there is physical contact between two small parts that results in wear, then damage, then failure.
This design affects almost a half-million Volvo gasoline cars.
If you’ve got a 1999-2002 Volvo that goes into “limp home” mode or has erratic throttle behavior, your Volvo may be suffering electronic throttle module failure, and you’re probably angry.

Where Things Stand Now
Owners are still “on their own” with this failure, but less “on their own” than they were before 2006. Now Volvo will pay to have the electronic throttle mechanism replaced under a 2006 recall, but this can follow great cost to the owner because dealers require many parts be in 100% working order before a new ETM replacement work order is declared.

First, we’ve got an entire sub-forum dedicated to the Volvo ETM problem. It’s called Don’s Room, named after Colorado native Don Willson, a man who spent years working to make Volvo take responsibility for this part.
