Replaced the driver side rear sensor and finally got rid of that pesky light. I swear you can’t trust mechanics anymore. I did the installation without jacking up my truck or removing the wheel. My truck has a 6” lift.

Worked great in our 2013 GMC Sierra 1500 pickup, had a few glitches with the old one but once we got it out & the new one in, it worked perfectly & solved the warning light issues. Definitely would recommend this for anyone that has the Stabilitrak, TCS & ABS warning come on, especially all at the same time like ours did.

This ABS wheel sensor is an OEM unit, P/N 20938121, an exact replacement for the original sensor. This took care of my intermittent DTC "C0050."

Perfect oem match. Did need to tap in with small hammer. Don't forget the high-temp wheel bearing grease on sensor housing. Old sensor was harder to remove than it should have been due to corrosion. Light amt of PB blaster + Torx-30 on a 3/8" ratchet w/ extension + flathead screwdriver + curved needle nose pliers + careful twisting/pulling worked well enough. It's a simple job, but not quick. Take your time to avoid problems.
