Ford F53 Chassis/Triton V-10 Speed Sensor

Darrell & Mel · 05-17-2007, 04:16 PM

I am trying to track down the cause of my speedometer malfunction. As I have stated in my previous post, the speedometer reads about 30 MPH when I am at highway speeds. Around town it may read any where from 0 MPH to 20 MPH. The odometer and all other guages work fine. Can anyone tell me where and what type of speed sensor is installed on the F53 Ford Triton V-10 chassis? I do not think the instrument cluster is bad; the coach only has 26,000 miles on it. Thanks for your help.

It has to be the speedo head. The rest of the stuff runs on a pulse from the speed sensor.

So, are you saying that the other gauges (odometer, tach, etc) all run off the signal from the speed sensor?

You will find the VSD speed sensor located on the left upper forward area of the differential housing.

When my MY2000 HR Vacationer was still fairly new I had problems with the speed sensor on the rear axle. Only my speedometer would quit functioning. Ford replaced it the first time. The second time I paid for it (not very expensive). Most of the time stopping, turning off the ignition, and restarting would take care of the problem.

We were in Tuscon in March 2004 for another problem when the mechanic mentioned that Ford had created a grounding update for the F53 chassis. The mechanic installed it and I've had zero problems with the speed sensor. Seems the MH manufacturers did an inadequate job of grounding.

SRT,
I changed the speed sensor ($21) the other day and took my coach out for a test drive. To my chagrin, the speedo still did not work. I finally gave in and took the dash apart and removed the instrument cluster. My wife then drove 2 and 1/2 hours to Richmond, VA to drop it off with Southern Electronics. As soon as she walked in and told them what the problem was, the technician new exactly what the problem was. Said he'd seen it lots of times, even with F350 and F450 Fords. Southern Electronics turned it around in one day ($215), my wife drove back to Richmond to pick it up, and I just got finished installing it again. I will test drive it tomorrow and hopefully it will be fixed. I will post another update after the test drive.

Sorry, I never posted a follow up. We did go camping over the Memorial Day weekend, and the speedo worked great! So it did turn out to the the speedo part of the instrument cluster. If anyone needs work performed on their speedo or instrument cluster, I highly recommend Southern Electronics. You can find them on the www. They provided a quick turnaround for me at a good price. And if you are in the DC area to do some sightseeing, I highly recommend Cherry Hill RV Park. Nice, friendly staff, great location to the monuments with easy access via the Metrobus and Metrorail.

So now you have extra speed sensor for the tool box. Keep it and you'll never ever need it again, sometimes thats the way things work out. I'm glad things worked out for you.
