I recently replaced my rear wheel ABS s nor after getting a service ABS Service Stabilitrak and Service Trailer Break system warning. I took my truck into a shop that I deal with all the time and they got the code c0050 for a faulty right rear abs wheel speed sensor. I had recently had the same sensor replaced about a 18 months earlier. I got a new sensor and replaced it myself, I also cleaned the mounting face on the rear axle as I read this could cause some issues. After replacing the service lights were still on, I also took it for a short drive to see the sensor needed to seem some movement to reset the warning lights, all with no sucess. I have a multimeter and have checked grounds going to the sensor and there is continuity when I check the ground wire from the sensor. I am begining to think it is the ABS control module??

Yes, tried clearing codes but they would not clear. I have also applied some dielectric grease to the connector as well. Still no luck!

you said it was a c0050. What was the subcode?

DTC C0050 02

Right Rear Wheel Speed Sensor Circuit Short to Ground

DTC C0050 05

Right Rear Wheel Speed Sensor Circuit Short to Battery or Open

DTC C0050 0F

Right Rear Wheel Speed Sensor Circuit Erratic Signal

DTC C0050 18

Right Rear Wheel Speed Sensor Circuit Signal Amplitude Less Than Minimum

I am not sure exactly which code it was but the tech who ran the scanner said the sensor was showing it was open and replacing the ssensor nor should have fixed it after replacing the sensor it still showed the same results as the sensor was the problem. I have checked resistance at the connection back to the control module as well as tested the ground and there is no issue with either.

On my 2013 Chevrolet Silverado 2 wheel drive rear drum brakes. Code c0050-00 right rear wheel speed sensor circuit. Code would clear but after a few miles it would come back on. Replaced both rear sensors. Now the code won't clear at all. Cleaned and checked wires. Put old ones back on same problem. Won't let me clear. Any ideas. Please . Thanks. ART.

Did anyone ever figure out how to fix?  Replaced the ABS module but wheel sensor not getting power.  No 12v coming out of module.

 I also am trying to figure out how to tell if I have jl4 brakes with 10 series or except 10 series???

 

start of with updating your account info with the year/make/model/engine/trim level of your truck

 

somewhere there's a list of RPO codes, location varies w the year, that indicate all the options your truck was built with.

      No low range 4 x 4

      My 2015 1500 LTZ Silverado suddenly won't go into 4 x 4 low. It will go into 4 x 4 high.

      Transmission Woes :-(

      By asilverblazer · Posted

      Yep, just a quick reference point.    My main point being I’d do a thousand other things before I’d pay 10k for a transmission.    Speaking in ignorance cause I don’t look at these trucks, what is it worth? 20k?

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      I think users are going to want to pick their monitored parameters, which parameters they want to see first.    It should probably start with baseline at a minimum and adjust to learned, but be able to overlay baseline for comparison.   A simple severity level would be able to determine what type of alerting is appropriate or user selectable.    Why not use the OBD port though?   I think a phone connection would be a good idea, push notifications type deal.   Number 1 issue is having data is useless if you don’t know what the data should be under normal conditions.

      summer road trips in the 2026 2500HD

      I thought I would use your thread and add to it as I just did my first longer drive with my truck in the last couple of days. I drove from the Grande Prairie area of Alberta down to Edmonton and most of where I drove in the city was the ring road so fairly free flowing but a bit of stop and go as well in the city. Stayed the night and returned home and not too many stops along the way each way but every restart and certainly every cold start sets it back for fuel mileage. Why I say that is I see some people will cherry pick a fuel mileage leg after the vehicle had been warmed up driveline wise before hand and its a forgiving ( easy rolling drive leg for example ) and call that their fuel mileage which can give a false perception of reality. I was not heavily loaded at all but never the less the flip bak cover, rubber bed mat, various tools etc and extra jerry cans of fuel all way up to a few hundred pounds of dead weight so its not an empty truck. The cold inflation tire pressures are set more near the freezing point so once they are warmed up driving I was showing 45 front and over 40 rear and realize high inflation pressures would help a little in fuel mileage but certainly not the ride on our crap sections of highway. The weather was good so was not raining as that can really drag mileage down, in fact I had a bit of a tail wind on average driving home. Most people on here would never have driven on that freeway to visualize it but its got a fair bit of rolling type of landscape with numerous river valleys. For the most part I had it on cruise set to 62 although kicking it off if I caught it in time before it started down shifting and self braking going down the grades. Most of the more substantial grades its shifting into 7th I believe as 8th just doesn't have it. Total distance round trip was 643 miles and my overall average and I did refuel three times in all, figured out to 17.65 miles per US gallon. My best fuel mileage section refuel within all of this figured out to 18.46 and these are all hand calculated figures. I find if anything that the trucks computer can be over optimistic, sometimes its pretty close but other times its stretching it. On paper persay in theory the truck would have just about made it on fumes for that whole drive without refueling once.    Which made me think of the topic thread of the wonder if these trucks could do 20 mpg and that is a good question, certainly would have to be on an easy going flat highway, no head wind, the right temperature, not packing around a bunch of dead weight and puttering along even slower than I was I would suspect and going steady and not stopping to smell the flowers or take a piss !. It probably is possible but not without effort to attain that with the wind resistance and weight of these trucks. Of course on my drive most people are passing me if they have the power as per loaded highway tractors, never mind a lot of speedy vehicles but the speed limit is 68 and most are at or well over that.

      Ac not keeping up

      By Aimatdeer · Posted

      Monday looks like a good day for the dealer to test an ac issue. Hopefully it all turns out good.
