Steering Sensor Error

[JohnGalt]

Unclear of this is hardware or software issue yet, but floating it to see if the Bronco6G f
brain trust has any info…..

Any others experiencing Steering Angle Sensor fault? Any hints on resolving?

I was at the local track, pushing hard yesterday, came home and washed truck including spraying out mud from underside. When I backed downhill into my garage with a full lock turn, I got a nasty sound which I assume is coming from the steering rack. Also noted that after I straightened the wheel, the reverse guidance lines on back up camera view still showed full lock. The truck steers fine otherwise.

A quick DTC scan indicated a number of errors centered around PSCM and modules receiving bad data from the PSCM. The rack is a 74 Weld case with my OEM internal with roughly 40k miles.

This is with steering wheels straight, note the reverse guidance still showing full lock. I do have a DTC indicating the IPC is getting bad data from the PSCM, so this kind of makes sense.

The noise (ugh). Only happens in reverse, going downhill and at full lock to the drivers side. The video was while I was at a full stop. After resetting DTCs and the PSCM module previously, I got down to only PSCM and VDM codes remaining. It throws the majority of codes and warnings when this scenario happens.

My guess is that the pinion bushing has failed enough to allow the plastic ring , with little gears to become damaged. This sensor will throw things off, but doesn't explain the weird noise. Has the rack separated somewhere in the center???

The indestructible/aerospace grade 74Weld gear strikes again....

Zero shade nor ill will to you @JohnGalt . I hope this is simple/fast/cheap to resolve.

Since I know squat about the rack internals and sensor, I’m letting ford take first pass at this. clearly it won’t be under warranty, but I’ll get some directon. Can’t see how the rack could separate in the center, but we’ll see.

thanks for your insight, I appreciate it.

Thanks! I may take you up on that. I’ll message you when I know more. Trying to get this resolved before the Mojave trip!
