2021 TPMS Sensors - 2nd Set of Wheels

[DukeofYYC]

Hey All,

Canadian here with a 2021 Yukon SLT.  Put my winter tires on the stock 20 inch tires, and will be buying 22 inch rims and tires for the summer.

Do the 2021's auto learn the TPMS sensors, or do I need a tool to teach them?

Thanks!

You’ll need a tool

Owners manual says they auto learn....Discount Tire told me the same thing...but dealer used tool to reset when they all read zero on my 2021 AT4 Yukon.

Okay there are apparently two different yet unique sets of TMPS sensors that work for our 2021 Suv's you can get the old style looking sensors but they have to have a 4 on them, not the CE of the sensors of the past. These will work but NEED a tool to program them (my amazon tool worked fine). They will NOT auto learn. I have attached a screenshot of the tech link article regarding this.

 

There is also the newer generation sensor that is designed to auto learn, the sensor is physically larger. These are labeled 4S and these are the auto learn sensors. See other attachment. 

 

Hope this clears things up.

Old post I know, this does clear things up on something I'm trying to make work.
