Message: [QUOTE="Injected79, post: 1302820, member: 5338"] Hey guys have been fighting and speedometer issue. Truck is an 05 f250.for the last 2 years about 2 to 3 times per year speedo would bounce around or drop out for a few minutes but would clear up and have no issues for 6 months then randomly it would start up again.. well now it is consistently not working. When you first start the truck to leave it will work for the first couple of miles but as it warms up it starts bouncing a little, then as it gets worse will bounce 20-80 mph, next it will then just sit at zero, what ever the speedometer on the dash reads my scan gauge reads the same which leads me to believe it is not a cluster issue. I have no abs code, cruise control will still turn on and work until speedo bounces around then it tries to stay caught up to what ever the speedo is reading. I went ahead and ABS in rear diff, no difference which I didn't expect to fix the issue. IF I look at up a vehicle speed sensor it shows one for the transmission output speed sensor. does the output speed sensor operate the speedo? any ideas? [/QUOTE]
