I have a 1999 Caddy DeVille with two problems. The speedometer doesn't work and the traction control light comes on. Could these two problems be related? If so, how are they related. Also, where is the traction control module located? Could it be as simple as a blown fuse. I am assuming that the speed sensor is the sensor located on the top right side where the axle comes out of the engine. If so, after removing it reads about 1200 ohms on a digital meter. If this is a magnetic sensor then being an Electrical Engineer, this would seem to be OK. However, I haven't tried to replace it yet. Would it be a good idea to replace the sensor anyway? Any help would be appreciated.

Thanks,

 Glenn Sr.
