Analog speedometer does not match digital speedometer by a lot

[got3fords]

Yall are killing me lol IT IS NOT AVERAGE SPEED! Look at the blurry picture better lmao it is DIGITAL SPEED ? I’ve added an actual picture with “Average speed” so yall can see the difference ? rotflmao

The difference between what, sitting in Park with Average Speed showing and driving with Digital Speed showing? That doesn't make sense.

Please look and see there’s a clear difference between “average speed” and digital speed” in the picture I know one is blurry but y’all should see it’s actual speedometer speed not average ??‍

WOOSH

That’s clearly a problem - haven’t encountered it - first I’ve heard of it on the forum - visit your Ford dealer - leave these photos at home.

Just looked at mine, digital and analog match, but I was in drive. Does that matter?

Speedometer cable needs lube lol...not...

It's that damn speedometer cable carrier bearing. Thing needs grease again.

Hell a Ranger just in park is worth 32 mph. Think what the truck can do in drive! Taco can't touch this.

Aside from the first pic showing average speed, it also shows 32MPH while sitting in Park on the analog gauge.

Good catch!

My truck only does 0mph in park.... is Shelly defective?

So as I posted above - this is a normal reading, it defaults to last known speed if communication is lost for more than 5-seconds.
so failure occurred at 32 MPH.

I have a hunch the OSS is dropping, requires transmission pan to be dropped to get to it.
OSS - Output Shaft Sensor
Might get lucky and just do a IPC self test to reset the locked in code

So this is related to tranny issues since the sensor is inside the tranny??

It’s not safe to put your truck in park while going 30mph….

Is this why you had to get your tranny replaced? I can live without a speedometer. Cops in Florida drive 15+ over the limit anyways.

I’m having the same issue with my speedo not matching the digital. It’s very intermittent and it happens occasionally but it is very annoying. Took it to the dealership and they said they can only diagnose it if it was happening at the time it’s hard to get it to replicate, I think I figured it out though when it’s wet or the tires spin, it will throw it off and then it just never syncs back up. Not sure exactly it’s been happening for a while. Just came across this post. Thought I would share my experience. Not sure the exact problem. Don’t want to take it back to the dealership because I’ve made too many changes on Forscan. I’m afraid if they do a flash reset or something it will mess everything up and have to replace a lot of modules. No thanks.
