Sounds like your steering ratio is too low for your comfort. I'm not familiar with the 2019 EPAS but look in to raising your steering ratio. With a lower ration, the ties turn more for the amount of input from the steering wheel. With a higher ratio the steering wheel needs to be turned more to get the wheels to turn the same amount as they would with a lower ratio. If there isn't a programming option for you there are devices such as a steering quickener to mechanically alter the ratio.

You should also have the PS hydraulic pressure tested at higher speeds. The speed you're going effects the pressure. The faster you go, the pressure goes down. Basic principle anyway.

Considering the E in EPAS stands for electric, if you're looking for a traditional power steering pump being driven off the belt, you're going to be surprised...

There's more than one way to do EPAS and as I said I'm not familiar with Ford's 2019 EPAS. If it's strictly electric than this problem for the OP is a "simple" programming issue as in Ford's AiM EPS systems. A strictly electric EP(A)S uses a motor to control the weight and speed of steering through a feedback circuit. Steering sensitivity is adjusted with motor voltage. Many EPAS systems are actually hybrids. An electric pump can be used, so no belt, or hydraulic fluid in the rack is under pressure to control steering speed and weight. As I said, what Ford has put in this truck? I don't know but I do know Ford has used many hybrid steering systems. Simply putting "E" on something is a long way from defining what that "E" means.

Bear in mind there is EPS, electric power steering, and EPAS, electric power Assisted steering. Assisted can mean different things in different systems.

"I don't know about what's in an F150, so I'm going to spout off a whole bunch of words about all the different electric and electric-assist systems out there instead."

The F150 service manual puts it quite succinctly:

Have another beer.

Nothing I wrote is inaccurate and a good explanation about why the acronym EPAS means more than one thing. I also didn't avoid my lack of knowledge about 2019 F150 EPAS system to explain why I including the possibility of hydraulics. Considering now your extensive knowledge of reading and manuals, please feel free to explain how Alexander can adjust his steering sensitivity. Of course you have the knowledge of AiM's feedback control considering Ford's EPAS, non-hydraulic, is used under license from them. No need for me to help him with that now that you here.

I believe what tvsjr is saying and I have to agree is stop being a troll. Before you come spouting off and telling everyone how to remedy the problem maybe you should do your due diligence and research the implemented system and root cause.

Boy, you must be a politician! More words that provide no information. I pointed out the inaccuracy of your initial statement... never said I could answer his question. The sensitivity certainly isn't user adjustable... it's perhaps feasible that some adjustment in the PSCM could change the steering sensitivity, but that's not documented by anyone yet. And the EPAS rack has nothing user-adjustable on it.

Now you want to make it my fault and still insinuate that you somehow have insider knowledge because you can use some big words and talk about "AiM" - whoever they are.

If you're so bloody smart, perhaps you can answer his question? Maybe even with something more useful than "check the hydraulic pressure" on a system that isn't hydraulic?
