Tire pressure sensors@!#!#!@!

[SilverGriz]

I officially hate tire pressure sensors. These things are total pain in the @ss. So I just rotated my tires and the system is now indicating that I need to check the rear tires. I rotated front to back and the systems still thinks the tires are in the same location. Anyone know how to program the system so it can relearn the actual location of the tire pressure sensors? I have a 2008 Chevy Silverado. Thanks!

You will be constantly fighting with it until you fill 'em with nitrogen.

I finally broke down and pulled out the owners manual. Believe it or not they actually told you how to do it. I thought for sure it would say "see dealer". Car companies have the most random ways for the systems to relearn things.

1. Turn the key to run without the engine running.
2. Use the keyless entry remote and hold the lock and unlock buttons for 5 seconds. The horn will honk indicating that the system is learn mode.
3. Start at the drivers side front tire and increasing or decrease the tire pressure for 5-10 seconds. The horn will honk once the system learns the location. Proceed to the passenger front and repeat process, passenger rear and finally the drivers side rear. The horn will hook twice once complete.

I'm still shocked that it actually worked correctly the first time I did it. The sensors are now reading the proper locations and the light on the dash it out.

I'm glad you found it in the manual. Take the other guy's advice and buy nitrogen. It's more temperature stable. Once it starts getting cold, you'll be constantly working through the GM menus because of low tire pressures.

nitrogen is not more stable, a gas is a gas, air is air, its the size of the nitrogen molecules that makes it ever so slightly better than plain air.

google it

Most tires are filled with compressed air, which when dry consists of about 78 percent nitrogen, 21 percent oxygen, and 1 percent other gases by volume. Water vapor (humidity) can make up as much as 5 percent of the volume of air under worst-case conditions. Filling your tires with nitrogen mainly does two things: it eliminates moisture, and it replaces skinny oxygen molecules with fat nitrogen molecules, reducing the rate at which compressed gas diffuses through porous tire walls. That means, theoretically at least, that a tire filled with nitrogen retains optimal pressure longer, leading to more uniform tire wear and better gas mileage. The commonly quoted figure is that tires inflated to 32 psi get 3 percent better mileage than at 24 psi.

If anyone fingers it out... shoot Chrysler an update PLEASE!!!! My 08 Jeep is a royal PITA with the TPM. I can adjust pressures weekly and it still don't work right

Oh, and dealer is too frackin retarded to know how to fix it

AMEN!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Key in the ignition turned forward.

Hold the lock/unlock buttons down for a 10 seconds or something.

The dash will say it's in tire program mode or some sh!t.

Then start at the driver side front tire and let some air out.

The horn should beep.

Move on to the Passenger side tire and repeat air release....horn beep.

Passenger rear

Drivers rear

Done

STUPID in my opinion! All because people can't check there air pressure in their tires. This is a direct result of the Firestone lawsuit and the Ford roll overs.

I don't want to have to run 75 PSI in my rear tires when I'm driving in the city or in the woods.

Sorry...this is a sore subject for me. The best is in the fall when air temps fluctuate and in the morning you get the air pressure alarm but drive for 10 minutes and it goes off.

Again sorry for the rant.......

09 2500 GMC, dealer lowered the alarm to 40 psi, no more issues

by the way, tire stores have a tool that they use when rotating tires, they just stand near tire and push a button, it tels truck what tire it is

Living in Alaska my truck and my wifes new jeep would always have that light on when the temps drop below -20, so does everybody elses new vehicles that I know. I would check the tire pressures and everything would be okay, I just got tired of dealing with them. When I put aftermarket rims and tires on both vehicles I just had the tire guys remove the valve stems with the TPS. I just ignore that little light down in the corner of the dash and never think twice about it anymore.

chevy also......updated

don't forget about the spare, have seen a few toyota's with the tpm light on and the cause was low pressure in the spare...

You mean you have to go to each tire and put air into the tire for this to work?

I believe the TPMS is part of the TCM. Blackbear can tune both the PCM and TCM and eliminate the TPMS. I'm hoping to having this done fairly soon as I also hate it.
