I've got a 2017 with the 2.7, 3.55, and about 45,000 miles

Long story short, hopefully won't still be long.

Drive about 11hrs this weekend, and around hour 7 I got a bunch of notifications in the cluster: Service AdvanceTrac, Hill Start Assist Service Required, steering assist service required. I lost my cruise control, and my rear parking sensors as well

When I got home, I plugged FORScan up and it said I had a bad front left ABS sensor. I replaced that today and am still having the same errors and code via FORScan. The one I removed was insanely dirty. I sprayed some WD-40 around in and around the sensor opening.

I've done some research on these faults and many claim the fix is to replace the throttle body. This doesn't make sense to me since FORScan is literally telling me it's the same ABS sensor, but hopefully somebody can help me out.

Any ideas? My dealer in town SUCKS so I'm avoiding taking it in, and I'm also pretty mechanically sound.

Thanks in advance.

 

Mine does this every winter at least once when driving on snow and dirt roads. I power wash at the car wash and it doesn't come back until the next year

 

90% it's the throttle body...my truck was identical in symptoms & there are many data points about this. The tb's are a failure point...

 

Thanks. Absolutely nuts that it may fix the issue(s). It just literally makes no sense LOL

One of the symptoms I've found others to have that I do not is a loss of power. I haven't noticed a difference in power at all.

 

I'll run it through a car wash and see what happens

I'm in West Texas. Snow is a rarity and hasn't occured yet. And over those 11hrs of driving to South TX, North TX, and back to West TX, I think the coldest weather I drove in was in the upper 40's.

But it's definitely worth a shot.

 

I think it is more a combo of snow and dirt roads that throw this, but so far 3 times and same conditions each time.

 

I have a 2009 Jaguar XF that was designed when Ford and Jag were close. A similar problem was known to occur with those when an abs sensor failed: the car would hiccup and show all kinds of strange error messages. I would not be surprised if the sensor tech and computer were closely related between the two marques giving similar fault syndromes.

 

My 2020 did this back in September. I was driving down the road at about 50 mph and went to accelerate and all of the warnings popped up on the cluster at once. They came up in the Ford Pass app too. It went into limp mode and after getting it home I shut it off and when I turned it back on the warnings were still present. After letting it sit for a few hours the warnings went away, but now I have a vibration in the steering wheel and gas pedal when driving. I’ve taken it to four dealerships and none have fixed it.

 

Interesting. The only fault I have that it looks like yours has is the hill start assist. I didn't and don't have a loss of power. The truck drives as normal as can be, I mainly just don't have cruise control.

What all have you guys done to it to try and fix it?

 

Please, no one laugh, and I'm not saying this is a fix, try a KAM reset. I've gotten weird warnings and pop ups over the years, and luckily that solved the warnings.
These things have very strange electronics, to me at least. I hooked up lights to my console shifter gear positions, and lost my cruise. Did a KAM reset, and got it back. Not a clue in the world that what I did had anything to do with cruise. Just a thought.
