1991 GMC Sonoma Repair Question
Asked on February 18, 2008
1991 GMC Sonoma speed sensor?
My pickup's digital speedometer jumps all over the place from time to time, really fast, from 0 to 185mph to 30mph and so on, and then will settle down for a while, but it usually shows only half the speed I'm really going. It even jumped around when I was sitting still in my driveway. There is no check engine warning light. How do I go about finding the speed sensor and replacing it? Engine is 4.3 V6.
