I got all mine on eBay. I got six for probably about the same price as two from the dealer. Only question I have and maybe somebody knows the answer is.... Are there batteries on them that I can change?

Batteries are not changeable.  Old units with dead batteries have to be replaced with new ones.

Can someone give me a part number for these sensors?  I think I'm gonna look for some online first rather than going through the Dealership.

Does anyone no if you use aftermarket sensors do they display the tire temperature as well as pressure?

Has any had any luck with the aftermarket sensors?

I want to buy a set but really having a hard time spending $300 on four sensors.

The ones I bought on eBay work temp and pressure. Also appear to look exactly the same. I do have one that is slower to connect and have to drive some to get it to work. It also will stop connecting for a minute But starts again quickly. They were somewhat difficult to learn once on the trailer. However I had synced them when I first got them to test from in the cab. I ended up using that trailer profile instead of a new one. Two complaints is they only go up to 102 psi. My tires require 110. Also had to use the band clamp ford method in wheel as my trailer wheels had larger valve stems than what GM supplies.

You just need U1D for the sensors to work.  PTT is the sensors themselves.  

 

This is the set that came with my ordered truck.  GM p/n 84152501  Made by Shrader.  433 mhz  I suspect any 433 mhz sensor would work, but not positive on that.

I know this thread is a little old, but I researched this like crazy so I hope this will help some one else.

 

I bought these same ones off of ebay - 4 for about $115 and had Les Schwab install them for me ($35).  Search ebay for the part number XY74 has above.  They work great and show psi + temp in the GM advanced trailering app in the truck.  The one thing to note is that I did not get the horn honk confirmation during setup, I had to let air out for 3-5 seconds and just assume it was detected (which it was).  I then re-inflated all tires after the setup.  I have a 2020 GMC Sierra 1500 SLT with max trailering package (nht) - crazy that they did not come with the truck, along with trailering mirrors...

Sensors require that the truck that the U1D option to function, but are not included with U1D.

 

PTT         Trailer Tire Pressure Monitor Sensors, includes set of 4 sensors. Sensor functionality requires (U1D) In-vehicle Trailering App to be ordered with the vehicle and installed by the factory. Sensors will be shipped loose with the truck and will need to be installed on trailer by customer. System is capable of monitoring up to 6 wheels. Additional or replacement sensors are available through GM Accessories

 

U1D    In-vehicle Trailering App, System, includes checklist, trailer maintenance reminders, trailer security alerts, trailer mileage, tow/haul reminder, trailer electrical diagnostics and Trailer Tire Pressure Monitor System module

Includes trailer tire pressure monitoring alert ONLY when (PTT) trailer tire pressure monitor system is factory ordered and sensors are installed

 

 

 

Is the U1D feature included on the SLT. I just ordered a SLT with all the bells and whistles, and the tire pressure sensors, but on my build sheet I do not see the U1D package anywhere? If I have the SLT Convenience, Technology, Driver alert I & II, Premium Plus, Preferred and X31 packages will I have this? Not sure if U1D is for Denali specifically or not. Thanks.

U1D is standard on 1500 and 2500 SLT/AT4/Denali

 

Trailer tire pressure sensors (PTT) are optional so need to be ordered separately. 

System is capable of monitorng 6 sensors, but PTT includes 4.  Order guide suggests GM Accessories if additional are required (3 axle trailer, or multiple trailers) 

 

 

I'd expect, but haven't confirmed, that the order system would kick out the PTT code (sensors) if the ordered vehicle isn't equipped to monitor them

Good to know, I ordered the sensors with the truck.

I just had my tire shop install 4 more of these on my car hauler trailer yesterday.

I used GM part # 84152501

I purchased them for $65 off eBay last week and they showed up Monday afternoon.

The tire pressure and temp show up on the truck display.

I have 3 trailers set up with these, the only issue I have seen is that during setup the truck only indicates pairing success on the screen, no light flash or honk. I just have someone sit in the truck with a walkie-talkie and let me know when the pairing has completed for each sensor.

Based on this picture, do I have it?

20200422_175842.jpg

Sorry to revive a dead topic here, I am trying to figure out how to get this to work on my truck. I have a 2020 LTZ, which from the ordering guides I have looked at, has the U1D package.  I don't believe that the PTT was optioned on this truck.  I have requested a build sheet to confirm the options.  I took off my rear license plate and it has the Schrader box that mounted in the photo above.  From the research I've done, it seems like thats the transmit box.  When I setup my trailer, it never gave me an option to monitor for tire pressure.  Do you need to have the sensors in range for it to show up as an option in the onscreen trailering app?  I don't want to order a set of sensors if its never going to work on my truck.  

 

Appreciate the help!

    • Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.       
    • We drove about 15 minute east today to visit a friend and saw a steep increase in price in the same county. About 50 cents a gallon steepper. 
    • Sure about that? A degree wheel and a dial indicator would lower your degree of assurance in that statement. 😉    It why we have offset keys and dialable timing sprockets. Just say'n.... I've built a few and have never seen one "On the money". 
    • I will admit I haven't experimented much with pressure drops beyond the numbers I put in and part of that is that the numbers I used are fairly low and then found out it would trigger regardless at that 35 psi. Having said that I had tried before had changed the placard pressures and being that I have a 1 ton set to 80 on the placard for the rear I believe it triggered close to 60, the front I don't recall now for sure but thought maybe it could get close to 45 from that factory 60 placard pressure. So I never did figure out if it was a number of psi from placard pressure to the alarm or a percentage of the total placard number as some figured it was like a 25% drop from placard pressure would trigger it. So as to try and answer your question, I believe I set the placard pressure on the front to 47 or so and while I run the front tires at 40, they have dipped below that some if its colder and I haven't put "winter air" in yet and never once have had the front alarm go off. I would say that the answer your looking for is no, that if you set your placard pressure to 45, you have a certain amount of room to drop below that pressure before the alarm will go off.    The pressures you decide to run in your truck, that ends up being what makes sense to you based on what your carrying in your truck or if towing, then have to bump them back up to something that will carry the load in the rear and the fronts typically left at the same pressure. It all comes down to that chart I put the link to and using an accurate roadside scale to be your guide, both unloaded and then loaded to know your minimum safe pressures.    I just wish GM would allow a person to change the readings for the tire pressures to the English system of pounds as I have to look at that goofy metric reading that will never ever jive in my head and will go over and change it just to figure out what they are if need be and then change it back. 
    • That part I understand, that the dealer can do it. But I'm not understanding why updates that were available to the truck since it left the factory, or the dealership originally, would not still be available to it without dealer intervention.   I'm thinking along the lines of recalls. They stay available until they are completed, regardless of whether they are in warranty or not, or in the hands of the original owner or not. Why not updates as well, especially since some of those can be safety related also?
