Drive by Wire? What years offered it?

Chuckster · March 4, 2004

I have a 2001 Tahoe, and noticed I have the same drive by wire (Throttle) as my C5... I was wondering.

When did they start offering this on a truck? What years have it? Is it model based? The C5 had it in 1997..

I believe 2003 was the first year for electronic throttle on the trucks.

Obviously it came earlier than 2003 if a 2001 Tahoe has it. Anyways, I believe it you got the drive by wire if you got the optional traction control.

I know the 2001 GMC C3 had it, and all the Sierra Denali's too, since it is the same as a C3 but with Quadrasteer.

I have Traction Control... I am sure now that is one way to get "DBW"

When Traction Control kicks in it is easier for the PCM to shut down the throttle blade then to start pulling timing and feul to accomplish the same thing. The latter requires much more intelligence.

The GM diesels have been throttle-by-wire since 1994. Kinda strange to think the Corvette inherited technology fom the 6.5TD now isn't it?

Don't any of you closet diesel heads go crazy on me, I know diesels don't have throttles, but the general public glazes over when you start talking about percentage of accelerator application.
