Hello, new member here. Glad to be here and working on my daughter's 2013 2WD. I see this is a common topic and I've read all the posts I can find and need some guidance please.
This truck has the electric power assisted steering, EPAS. It stopped working suddenly with dash alert "Power steering assist fault" and "Service Advance trac". The code reader at the local parts store says U0428-F0 "Invalid data received from steering angle sensor module".
Avoiding the dealership at all cost for anything and being able to work on the car myself, I'm trying to diagnose correctly before buying parts.
A retired Ford service advisor looked into it and told me to replace the steering angle sensor for around $50 as a cheap test.
Turns out that $50 sensor is for hydraulic systems and mine is integrated into the steering column housing assembly at closer to $300 to $350. Then it requires an alignment and calibration at $290 + $129.
That's no longer a cheap test. A new Ford steering rack I think is around $1000 online and I can install myself, then calibrate at Ford for $290, if that's the way I ultimately need to go.
I also understand there's a torque sensor somewhere, maybe in that column assy.
Here's what I've done so far: -Disconnected the battery for 15 minutes. Reconnecting does not solve the issue even temporarily. Service advisor said if it does nothing, that points to angle sensor. If it solves it temporarily, that points to the EPAS module in the rack. -Cleaned the contacts on both plugs at the steering rack control module. -Checked the 125A megafuse at the battery and 5A fuse in the fuse box. -Bought a cheap code reader and nothing comes up when plugged into the OBD port.
So is it possible a local repair shop could possess the proper diagnostic tool to pinpoint the issue before buying parts? Or can Ford even tell which part is needed with certainty?
Rock has a Dorman rack assy that comes with DIY calibration somehow for less than $1000, but I'm avoiding aftermarket parts on this one. What's the advice here? Need to save this college student and me some mula!
Anybody have experience with the Dorman steering rack if that's whats ultimately needed?

do yourself a favor and get the auto-switching one
it may or may not be able to help further diagnose it but if you're gonna be working on this thing it's extremely helpful
