I'm looking for any and all info about making this system work on my Sierra - only because my new wheels already have the sensors and I can't imagine that the Yukon/Denali's have that much more different parts than the sierra.

 

Is it a factory option that just isn't enabled on the Sierra?

No pickups come with tire pressure monitoring. Don't ask me why. If they put 20" wheels on your truck at the dealer, I'd say they put the wrong wheels on it (they come all assembled/balanced with tires, sensors, etc.) if they have the sensors in place.

 

The same thing has happened at our dealership. Worse yet, they've put 20's without pressure sensors on Tahoe's and Suburbans and delivered it that way, only to have the customer back the same day or next with the "Service Tire Monitor" message displayed. Then they have to scrambled to get the right wheels.

 

The receiver is in the passenger door module and of course the cluster has to be able to display the tire pressure information or at least the fact that you have a low tire. Programming of these items is by the VIN (so it knows what options you have) and we don't have the luxury of being able to turn on/off whatever options we want, so there's no way that I know of for the dealer to enable TPM on your truck.

Here is a question for you about the tire sensors. I just installed 20's on my 05 suburban and ofcourse I forgot about the sensors so now I get a "Service Tire Monitor" message displayed on the cluster. Can I goto the chevy dealership and get the sensors and installed them so everything is back to normal??? Right now when I see the message I just hit one of the buttons to get rid of the message. thankx

The sensors may not fit properly if they're not factory 20's. But yes, if you can install the sensors and they can be learned, everything will be back to normal.

So when the system is actually working it only show "Service tire pressure" or something similar? Not the actual pressure numbers in each tire?

 

As for my wheels, these weren't factory installed, they're just factory wheels...make sense? I purchased them recently from a GM dealership. I was just wondering how the system worked and if it was possible to adapt to my truck. I would think that my cluster has the ability to display the numbers or messages as I would sure think the Sierra's and Yukons have the same cluster. And for the module - maybe just pick up one from a salvage yard....all this being if I was really wanting to make the system work. And if I don't get actual pressure numbers, just some generic display, I'm not that interested proceeding. I can make visual "check" of the tire pressure (which I find myself doing) before I get in the truck. I was hoping that the system provided some hard numbers as to each tires internal pressure.

If you have the steering wheel controls, you can page through the driver information center and display each individual tire's pressure. If you don't have steering wheel controls, you'll just get a low tire pressure message and will have to go around and check all the tires to see which is low.

Too bad GM enabled the individual readout feature starting in '05; guess in '04 GM must have reasoned that folks like myself didn't need to know how low a pressure a tire was running, nor needed a visual indicator to tell me exactly which tire(s) was low since GM figures if the tire is that low on air, there's no way I can't visually tell just from looking at the tire. :confused:

Well I do have the steering wheel controls....and if this is an 05 feature and I'm doing a custom install, it might not be an issue so much. I have a friend that is a tech at a local GMC dealer.

      DTC P2C48 auxiliary cooling pump

      I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be.

      OCI, not when but why?

      I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!

      I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify.

      I would not argue that with you. It would be pointless to argue against the truth and you speak the truth.    My question and in fact the entire point of this thread is an exploration into the levers of wear which happens no matter how well we maintain our powertrains.    Some of these levers we exert a good deal of influence over which can and do result is lower wear, longer powertrain life. Some others we are sort of stuck with.    An engine is typically done when the ring to bore seal no longer is able to do the job effectively. Normally the first thing to go in a engine otherwise well maintained and adult driven is this seal.    Looking into the means, methods, products and attitudes that influence the rate of wear seems a worthwhile inquiry to me.
