I understand that you are in the 2015 to 2020 section but it is going to be way easier for someone to help you if you give your vehicle info. Also, any recent work done on the vehicle? Code just popped up while driving or were you doing something else?

Changed which sensor? Manufacturer of the sensor? C'mon man.

Duly noted…On my 2020 Yukon SLT- here’s the issue::::The Stabilitrak and Abs lights came on last week, this was after a couple of really bad snow days. Code reader kicked out 4 codes that indicated the right front wheel speed sensor had a problem.
U0422-71, C0040-05, 08, 3A. I changed the sensor, cleaned out the area and installed GM sensor. Drove the car around the block but the same lights were still active, even after I cleared the codes.I plan on taking it apart and cleaning the area with brake cleaner thoroughly. Am I headed in the right direction?? Any help is welcome, smart comments are welcome also.

if changing the sensor did not fix the problem then it could be or most likely is the hub.
you could verify with a scanner and looking at all 4 sensor data at the same time
otherwise the hub may be making noise or may have other signs of wear such as being loose
you can check it by jacking up the wheel so it is off the ground, grab the wheel at 12 & 6 and see if it has any play, also check at 3 & 9 but there will be some play because of the steering. also spin the wheel and listen for ticking noise or grinding sound.

abs codes are the hub about 90% of the time, sometimes you can get lucky though

I was thinking it may be a bad hub or the module. (Hope it’s not the module)I shook it yesterday, didn’t feel any play at all. I did try to spray the sensor bore hole to clean the inside while spinning the hub. But Yeah, the truck slows down at low speed, especially while parking, very annoying!

so when braking at low speed the abs kick on?
if so and changing the sensor did not help, then you can put money on it being the hub

 

[Doubeleive]

also what is the mileage?

 

[Bigell]

Mileage is 108K….

Mileage is 108K….

bit early for a hub, but that's the primary suspect. The historical average is about 160k

 

[Bigell]

Yes….low speed, parking etc….

 

[Doubeleive]

Yes….low speed, parking etc….

that tells me the module is working, besides that's a very unlikely suspect. if it was the module you would probably have brake errors also, like service brakes, etc.

Got it…thanks for the help folks!!
