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.

    • We have now!  2027 GMC Sierra  Early look, but I'm a GMC guy and so far I think I like the looks of the Chevy better.
    • HD at the moment, are kinda their own deal.  How LTZ sells on those vs on 1500, there is a difference.   They are merging most of the mid trims on 1500.  LT, RST and LTZ are replaced by one trim, Silverado.  LT and RST are a BIG portion of sales.    Bad naming choice aside, the new Silverado trim will offer the spread of options that those three trims offered.  So expect to see things like the tech package for example, and memory seats.  And LT Trail Boss will now just be "Trail Boss" (formerly LT Trail Boss) but will offer content spread like the new Silverado trim will.  The press photos showed the Trail Boss (formerly LT Trail Boss) has access to Super Cruise now, which on the current truck was High Country only.       Here is the Trail Boss interior.  Memory seats and Super Cruise are present.  All things the LT Trail Boss it replaces, and the RST it was based on didn't get on the current gen.  You had to go to LTZ or ZR2 for memory seats, and High Country for Super Cruise.      
    • I installed a Hellwig rear sway bar on my 21 Sierra SLT, it made a huge difference on how the truck handles, no body roll, the trucks much more planted now. Not sure of the suspension differences between the 21 and 26,  if its body roll your having a sway bar will solve it. 
    • So a follow up and my fix. I found in online searches the live data to look at on a scan tool to verify the fuel tank pressure sensor was working.  It showed an spec number towards the lower end of the rang, but in spec.  Then while it was running opened the gas cap and the pressure should change.  It didn't change even a tiny bit.  The data for the purge valve said it was open...never changed. So then I measured the voltages on the plug for the fuel pressure sensor and they matched what it should be.  So local car quest parts had the sensor in stock...it was a bit of a pain to remove and an even bigger one to get it to actually go back in.  It helped to unbolt the driveshaft and bungie cord away from the gas tank to give a bit more room to work. So fuel tank pressure sensor in I cleared the code, and started it up.  I went to the scan tool's live data and... Eureka! The pressure number was different and fluctuated a bit.  So took it on a short drive and pressure number varied saw the purge valve go from closed to open and back to closed.  Drove it to and from work for roughly a week plugged in the scan tool no codes.  I took it in to get tested and passed.  In my state's infinite wisdom (oops meant greed), since I pushed the test with the maximum extensions I have to take it back in by Feb '27 to 'get it back up to date', then my next test won't be until Feb '29.
