Where is the output speed sensor located on a 2013 Ford f150?
The output speed sensor on a 2013 Ford F-150 can be found on the rear of the transmission where the driveshaft exits it. This sensor is able to measure the rotational speed of the output shaft and determine the vehicle speed by that.
How do you reset the speedometer on a Ford f150?

What’s the speedometer on a 1995 Ford F150?
Hi, I have a 1995 Ford F150 with a 5.0. My trucks speedometer works smoothly up to 33 mph but then will start bouncing (more aggressively at higher speeds) from random points.
What to do if your speedometer is not working?
If your Ford F150’s speedometer is not working, the first place to go would be to check the service engine soon light (if applicable). Now, take it out and see if the cruise control still works. If it does, that’s a pretty good indication that the vehicle speed sensor is just fine.
How does the speedometer work on a Ford?
The module works by receiving speed signals from the Differential Speed Sensor (DSS) and converts the signal input to the standard 8,000 pulses per mile output. The most common issues with the Ford speedometer are when it bounces back and forth continuously while the vehicle is being driven.
Why does my speedometer bounce all the time?
My trucks speedometer works smoothly up to 33 mph but then will start bouncing (more aggressively at higher speeds) from random points. I’ve read up and found that it’s often a VSS issue but my trucks cruise control works and will turn on just fine, but causes my speeds to change rapidly with the speedo bounce.
