u really don't need tpms tool to do trailer tires set mine up yesterday very easy just let air out of tire till horn honks then go to the next,,
was gonna order tool until I read owners manual..
Wow. Read the owner's manual, who does that? Glad that worked. I had the TPMS tool already for rotating my tires so it's a good $20 investment anyway as I don't think the let the air out truck works on the regular truck tires anymore unless they added that feature back for the 19s.

Got it to finally work. Had to delete Trailer profile and create a new one. Used my $20 tpms tool off Amazon... Shows tire temp and pressure which is nice. Sent from my Pixel 2 using Tapatalk

This one. It's like $15 on Amazon. It worked on my 16 z71 and it works on my 19 as well and did the Trailer tires. Sent from my Pixel 2 using Tapatalk

Gospel truth Member. I just did it this way on my 2019 Sierra and after reading the instructions in the owners manual and hitching up to the my single axel utility trailer, it took about 5 minutes following the prompts on the screen. In my case I did not have to re-create the trailer profile. I poked around until I found the option to add TPMS sensors, then chose a two wheel trailer and went immediately into setup. Thanks!

Hey Guys,

 

I just read my owners manual (last resort, right?!) for my 2019 Silverado 1500 and I agree with Trwtow, there is a manual method of programming the trailer TPMS components by increasing or decreasing the tire air for 10 seconds. I'll be doing this later this week. It also says that the trailer must be electrically hooked up to the truck. This is a great feature of the Chevy's! My truck also has the trailer brake gain factory installed and THAT is also an excellent feature!

Side note, I've hauled close to the gross max weight (14,800 lbs) up and down mountains from NC to South Dakota and it performed flawlessly! Cruising at 70 and rpm's about 1800! Fuel mileage average was 10-12, not good BUT it got the job done. I didn't have leveling bags and wished I had. I ended up having those installed once I arrived in SD.

Thanks to this forum I finally got my TTPM Sensors working. I bought sensors from eBay and received sensors with a different part number.  They wouldn't learn.  Contacted seller and he said these parts will work and has had no complaints.  So I tried again, jacking up one side of trailer so I could spin the wheels. It worked! So I learned the rear wheel while spinning the tire and went to the other side that was not jacked up and they learned anyway.  Problem was that I never heard a chirp of any kind from the truck horn or saw flashing lights.  Maybe because the driver door was open??  This should not be as hard as it is.

I just configured my second trailer to the system for TPM.

 

Simple as can be and have two different trailers set up and working.  Cool AF feature.

Great!!  How do you like the 3L diesel?  I almost bought one but payload forced me into a 2500.  What's your mpg?  Solo and towing?

Loving the diesel.  MPG on a recent drive - cruise set at 78 mph and averaged 25 mpg.  Towing a tall enclosed trailer about 13 mpg.  Simple comparison:  At least 25% better towing mpg and close to 40% better on the highway mpg.   I had a 19 with a 6.2L as a direct comparison.

Question, I can't find an answer to this online.

 

When towing and wanting to view the trailer pressures/temps, is your only option to click through the head unit?

 

Can you view it on your cluster under one of the pages? Does it show temp and pressure on the cluster, if yes?

 

Anyone know if you can set an alarm pressure or if there's some sort of alert system if you get a low pressure tire?

 

I'm trying to decide to go with the OEM tire pressure system, or save about $20 and go with a tire minder setup, which is a dedicated device and doesn't require remounting the tire to install the sensors. It has an alarm system, and could be moved between vehicles if I loan my trailer.

Anyone know if you have to buy the $150/pair GM Trailer Sensors (part # 84338125) or could you use another aftermarket sensor (that would be much cheaper).  I need at least 4 for one trailer and another 4 for another trailer.   My 2020 has the U1D option - Advanced Trailering Package where I can view the trailer’s tire pressure (and temp evidently).   

 

Is it possible to get an aftermarket that will connect to the ATP?

Yes, you can get after market sensors.  Refer to previous posts from me and others. I got mine from eBay for $60 per pair.  Bought the part number but got sensors with a different number.  I was assured they were the same item.  They did work but the horn didn't sound after being learned.  But they do work.

What psi are you guys running? Or does anyone know what the max is with the OEM sensors?  I have a single axle travel trailer with Goodyear Endurance trailer tires. Which I purposely bought for extra protection it's a load range D tire but to achieve max load I need to run 65psi which caused me to pay extra for brass valve stems.  I'd like to use the tpms sensors but like others have stated everyone locally look at me like I'm crazy when I ask about it.

 

Just wondering if I go through the hassle of taking tires off and getting senors installed if I'm going to be able to run 65psi with this plastic valve stems.  

Any input would be greatly appreciated

Seems like tire place would have installed metal or the new non-metal valve stem used for Load Range D tires when the tires were mounted.  But pressure depends on the weight of your trailer.  GoodYear has a table for weight vs tire pressure.  That's a start.  I had a small 20 ft single axle trailer that weighed about 4,000 lbs and aired my Endurance tires to 55 psi.  Seemed to work fine. I say experiment and chalk them to determine even tread wear at given pressure.

Just some tips for those still troubleshooting their TPMS connection if it doesn't work after following manual:

 

1.  If you need the larger size TPMS, Nichols Manufacturing out of Phoenix makes an adapter kit.  They are pricey, but they work!  I first tried using some from NAPA, but they didn't fit my rim thickness.  The Nichols Manufacturing ones worked perfectly.

 

2.  If you are not able to get a signal using the air down method, buy the cheap tool on Amazon referenced in this thread.  That worked for me, but only after completing the next steps:

 

3.  I had to rotate each tire so that the valve stem faced forward.

 

4.  And I had to back my truck up so that the rear was facing the trailer.  I wasn't hooked up to the fifth wheel as we were staying in it.  Didn't want to go through leveling, removing the tri-leg stand in the front etc.  First, I tried pulling up next to the trailer but was facing opposite direction.  Then it dawned on me that it may be directional.  Not confirmed, but it only worked once I turned the truck around and backed up as close to the trailer as I could.

 

 

You may have better results than me.  I had another 5th wheel with this setup and it worked flawlessly using the air down method, but that trailer was 38 feet long.  This one is 43 foot long.

      Cam chain tensioner question

      By B14Sierra · Posted

      So I'm in the middle of a DOD AFM delete on my 6.2 L86 Sierra. I had a pick holding the tensioner but after I got the Cam phaser gear off I was cleaning off all the rtv and apparently I didn't have the pick seated far enough in. I bumped it and the tensioner sprang forward.  I think everything is good but I want a second opinion. The top of the tensioner is just a looped piece of plastic that rides in that channel right? There is no spring or anything is there? I got the gear and chain back on and it seems tight and everything looks right. I'm hoping nothing fell out.

      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

      By Chuck FB · Posted

      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.
