Volvos Affected by ETM Failure
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. 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 (ETM) 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.
ETM Resources Here on MVS
First, we’ve got an entire sub-forum dedicated to the Volvo ETM problem. It’s called Don’s ETM Room, named after Colorado (US) native Don Willson, a man who has spent over three years (and counting) working to make Volvo take responsibility for this part.
There are many many more electronic throttle mechanism posts in Don’s ETM Room.
