tire pressure monitor system reset
- Thread starter kickstart
- Start date
You're best bet would be run by the dealer and have them reset them with their little handheld thing that they have... Mine did that one time and the machine showed that one wasn't working right, and they broke down the tire and realized something had broke on the sensor... Just an idea...

Tire pressure guage on dash is displaying inaccurate tire pressures. No problem till cold weather hit. Dealership has handled twice since October 2010 and will need to handle again at next oil change. Service Assistant and General manager has admitted to inexpensive part not making the grade and mulitple issues on different models of GMC's. No solutions in site.... I hope an accident is the result of tire pressure gauge failure. Best bet is to manually check pressure once a week.

One thing I have learned is nothing comes free from dealers anymore. If they can grab $10 from you they will! One dealer almost tried getting $0.25 cents from me for a standard nut that should have came with the truck to install an aftermarket brake controller.
happy 2011

year make and model would help
Just adjusted the tire pressure on GeeMSee (my 2011 GMC Sierra 1500) to 35PSI cold. Computer dash readings have been inaccurate, so I thought I'd read the owner's manual on how to reset the sensors. Says I need a TPMS relearn tool, see your local GM dealer. Cool, another tool for the garage. Called the dealership, they don't sell tools - darn. Found one on Ebay $150 - I HIT THE CEILING - $150 for a tool to make the computer idiot lights read correctly or I can drive to the dealership or tire store and have them reset the sensors. Is it just me or did the GM engineers really do something that stupid to prevent owners from adjusting their tire air pressure?
Found a relearn tool for $68 + tax + shipping from a link on another forum.
https://gmspecialservicetools.spx.com
and search for tool no. EL-50448 Tire Pressure Monitor Sensor Activation Tool.
Here's my comment from that forum
Just grudgingly ordered the tool. I am very, very angry over being forced to buy a tool just to have the sensors read correctly. Aside from having to visit the dealership or tire store to have them reset, I feel this is a liability issue. Tire pressure can be correct, which in my vehicles it is, but can be read by the sensors as incorrect. If you have an accident that is even remotely tire related and you could be on the losing end of a lawsuit.
Dealership was no help, as was GM customer service. I have talked with the NHTSA. Person there told me to NOT do any work on my truck and to take it back to the dealership for everything. What does your FLAPS (Friendly Neighborhood Auto Parts Store) have to say about that? An email to my US Senator hasn't been answered yet. Comments?

A Long-Winded Comment: The tire pressure law and its reality
As with most things in today's world, things are not as simple as them seem. The U. S. law as early as October 5, 2005 (see link)
http://www.nhtsa.gov/cars/rules/rulings/tpmsfinalrule.6/tpmsfinalrule.6.html#I
now is (copied from the text)
Requiring that the system must:
Also see the convoluted discussion about Calibration under "6. Test Procedures".
Also under "10: Maintenance issues" under "TPMS Maintenance:" you will find a discussion of the potential costs (one estimate $100 per episode), which were discounted by the governing body as "... that's not the way we understand it." While the estimate was high, the government's understanding seems to have been short of the ultimate reality.
This is not simple and it may not be technologically possible for each and every owner without installing some pretty expensive "standard equipment." There goes the price of your new car! My guess is that it can't be done at all without some pretty sophisticated hardware/software. (That there are some tools as low as $85 now is a tribute to our amazing ingenuity.)
So, the government, in its quest to make the world a safer place, has again imposed unaccounted-for costs on each of us -- people and businesses (dealerships) alike. You pay higher car prices. All businesses, whether they let us see it on the bill or not, pass their costs on to us -- the ultimate consumer. There REALLY is no true value of money except what flows from "we, the people" and our labors.
We all get angry when terrible accidents happen - some through simple maintenance negligence. Whether you think the government should intervene in this manner is up to your personal social agenda. Nonetheless, it did happen. It is the law.
So, businesses have been force to new capabilities that have significant costs in many areas. Things mandated by the government are seldom free or without imposed costs. Those costs are passed on to us. I know it feels good to be self righteously angry but complaining -- especially to the government -- is a waste of your vital energy.
I apologize for being preachy and am sorry for being slightly rude but my advice is "get over it."

...
This final rule requires installation in all new light vehicles of a TPMS capable of detecting when one or more of the vehicle�s tires, up to all four tires, is 25 percent or more below the manufacturer�s recommended inflation pressure [placard pressure] or a minimum activation pressure specified in the standard, whichever is higher.:

...
Requiring that the system must:
- "Know" what the placarded pressure is by wheel (and potentially changed by tire if you replace production with on non-production tires).
- Be calibrated to some unspecified level of accuracy so that it can measure that the actual pressure is withing the placarded range. (or to a possibly non-standard range if you replace the tires)
- Be accurate enough to signal when the pressure is down 25% to some unspecified accuracy.
