I can't get my trailer TPMS to sync with the truck, the sensors are working and are readable via TPMS readers at tire shops.  Is there a distance limitation on how far your truck can be away to pickup the sensors?  Even my local GMC dealer was puzzled and wanted me to leave the truck and trailer with them, I declined obviously. But may end up being a day down at the dealer to get this resolved.

Do you have the tpms programing tool? I just followed the on screen instructions, placed the tool against the tire sidwall adjacent to the sensor for a 5 count and moved on.

the gm trailer tpms sensors are 433MHz frequency. when i set mine up i learned the trailer tpms to the the module on the truck each way with the tool and by airing up the tires. both ways worked fine. the tool is quicker. i don't know what the max distance is that the module would still receive  the frequency from the  ttpms but since the module is right behind the license plate as long as the truck is in the hook up position it should work, if the sensors are correct i wonder if there is another problem.

They are GM 433mhz sensors per the tire shops tool, that's why im wondering if there is a distance limit.  Our fifth wheel is 41ft long.  I may just pull up right beside the trailer hook the trailer up via wiring and see if itll acquire being closer.

Hey Guys

For those of you that still haven't purchased your new truck.  I had the dealer order me the 4 sensors for $50 as thats what it would have cost if ordered originally.  They did so if you want them just push for that.  It was the last thing we did after getting to the price we wanted.  Just FYI

I had to order the TPS for my trailer and am waiting on them to arrive, I was told today that they may not fit alloy trailer wheels because of the thickness of the wheel. Has anyone installed these or ran across this issue on alloy wheels (tps part # 84338125).

Just had my GM Trailer TPMS installed in my 40ft 5th wheel.  Worked like a charm using the air down method.  It never honked the truck horn, but it did place a check mark on the screen next to the tire being aired down and then moved to the next.  I used GM Part number 84152501 for my setup.  It's not the 2020 specific part number, but worked just fine.

For those of you that have the TPMS sensors installed in your trailer tires, did you have to physically take in the trailer to the tire shop so they could install the sensors in each tire?

I did, but I suppose its possible to take all of your trailer tires off of the trailer and take them in. It was just much easier for me to take the whole rig in and set it up and make sure it all works there.

I used the sensors that were in the console, as I ordered truck with it.

They installed just fine in my alloy wheels.

they only will go up to 100psi tho, I have g rated tires and run 110psi. it is fine as the temp reads just fine.

Used pressure drop to pair them to vehicle, worked great, horn beep and all.

I installed them myself and balanced tires as well, I happen to have the equipment. And packed the wheel bearing while I was there.

Thats what I did.  Discount only charged $5 a wheel.  With the trailer up there they can use the tool to help program so you don't have to walk around letting air in and out

      Is it time to put a piece of tape over the CEL?

      consider doing electrical testing?  I would guess some power or ground wire/connection has a problem.   alldata.com has wiring diagrams, connector pinouts and diagnostic procedures you can use to find where the problem is.

      My First Project and GMC has me stumped

      By davester · Posted

      can you tell if the reader is actually trying to get codes, and the pcm is reporting none, or is your reader just silently failing because it's not communicating with the pcm?

      Any joy with this truck seems to be short-lived.   The CEL for P0172 ("bank 1" too rich) is now "intermittent".   I'm not sure where to check, or re-check, and my energy to keep chasing problems with junk is wearing thin. The P0172 seems to set as I'm coming to a stop, completely off the throttle, when fully warm. At least, that's what it's done the 3? times it's set.   Everything appears normal on the scanner EXCEPT long term fuel trim. There's only one bank on this vehicle because it's an OBD 1.5 with only one upstream O2 sensor. At idle, it's around -16.4% and will dip to -18% occasionally at idle or off-throttle. LTFT approaches 0 when throttle is held at 2500rpm. Short term appears normal, much closer to zero all the time. The LTFT tells me the engine is running rich at idle but compensating at higher load. But, why?   The EVAP purge valve doesn't appear to be leaking/sucking fuel vapor continuously. Is it sticking just as I come to a stop and the engine is choking on fuel vapor and sets the P0172? But that doesn't explain the persistently negative LTFT. Disconnecting the purge valve doesn't seem to make any difference.   I suppose that leaves another dang issue with the fuel injector. A leaking fuel pressure regulator, a new leak in the spider, or a leaking fuel injector/poppet valve I didn't see, or a small crack in one of the spider legs.   The vacuum line leading to the fuel pressure regulator doesn't have raw fuel in it. It doesn't even smell like fuel when it's pulled off, not until you suck air through it, then you can tell it leads to a fuel component. I'd consider that normal? Nothing is signaling this is a FPR issue from the outside, at least.   The oil smells like fuel but it's not building volume. I've noticed most oil in most engines smells like fuel to some degree so it's hard to say if the smell is an issue or not. Or if the engine just still smells like fuel because the crankcase was full of it a few hundred miles ago. But it's been changed twice since that original issue of the leaking fuel line dumping fuel into the intake.   Patience is running very thin. Every win seems to be accompanied by two steps backwards, or another issue that leads to removing at least the top half of the intake manifold. Enough! LOL

      Tire pressure for 37s

      By Chuck FB · Posted

      First off you mentioned "Toyo Says" and then gave the pressures 45/50, was this some person at the tire shop that pulled those numbers out of his head ?   Now of course I can't know your exact axle weights front and rear, however I have much the same pickup as yourself other than not knowing your starting weight as per the pounds the truck rolled out of the factory at due to the options yours did or didn't come with or what you have added beyond the extra tire weight. The correct way to know 100% where a person is at is by weighing each axle with the typical weight the vehicle is driven with and that means taking into account passengers and making sure you figure in a full tank of fuel and a little grace for whatever you may put in the bed "groceries" !    I am looking at and not that it really matters as all the tire companies use the same charts anyway, but I am looking at the comprehensive Toyo tire chart in the section that your tire falls under and I know it sounds confusing but your tire is not an LT metric tire like your factory tire but instead because its a standard inch measured tire its under a different category called an LT floatation series tire. That makes a difference as LT metric tires they don't want to see run below 35 psi at highway speed where as with the LT floatation series it can be run down to 25 psi on the highway as long as the weight on the said size of tire is agreeable with or less than that minimum 25 psi. It blows many people away that how is this physically possible, an empty truck for one thing and larger tires with the same size wheel diameter have a lot more air volume so they can carry the same weight as the smaller tire with less air pressure.    So my truck, I have the stock 275/65R20 wheels and tires and I have a bit of weight in the box with a bak flip cover and a rubber bed mat and some tools and spare gas. The front of my gas truck weighs a bit more than some trucks of the similar spec due to double batteries and alternators. However with full fuel and just me in the truck I am weighted such that I can run 40 front and 35 rear and so that is what I have done since day one.    If I base your truck at or slightly below the weight of my truck, in theory with your tires going by the tire chart you might be right around a minimum of 30 pounds front and 25 pounds rear. Of course that would hit pretty much minimum cold inflation pressure one could run with that tire size and a near empty truck. If you have access to an accurate weigh scale to do individual front and rear axle weights I would suggest you do that and make sure your topped up with fuel and whatever else in the truck before you weigh it and then you will have a great starting point to work off of and figure out what your bare minimum pressures are you can safely run. If you do much in the way of hot weather high speed driving, bumping up a bit for a safety margin is never a bad idea but just depends on what type of driving you do. I will include the Toyo chart and the floatation series sizes start on page 31. Without a doubt at these pressures I am speculating at minimum wise for your truck, it would most certainly ride very different then it did when you were using 55 lb front and rear.     https://www.toyotires.com/media/pxcjubjs/application_of_load_inflation_tables_20200723.pdf
