Re: have 08 tahoe dont know how to reset sensor
I assume you want to know the correct tire pressure. Look both under the fuel fill lid and on the drivers door jamb for the sticker that tells you this data. Order an owners manuel for the car as there is a lot of info you might be interested in
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

The low tire pressure warning should go out if you set all of the tire pressures to the correct pressure, then drive the vehicle for about a mile. You should not have to "relearn" the Tire Pressure Monitoring System (TPMS) unless the tires are (A.) rotated into different positions or (B.) There is a bad sensor that needs to be replaced.
For more information, you can read the information in your Owner's Manual. Here is a link to a pdf version 2009 Cobalt owners manual. (The information and procedures are the same for 2008 - 2010 Cobalts) The TPMS section starts on page 5-64
Sounds like you have a low tire pressure warning light on.
On the inside of the drivers front door there will be a sticker that tells you the proper tire pressure for you vehicle. Check all for tires and *** air if needed.
If one tire is particularly low it may indicate that it has a leak and needs repair.
Once all the tires have been set to the proper level the vehicle will need to be driven faster than 30mph for about 10 minutes and the light should reset. If it does not there may be a problem with a sensor communicating the wrong pressure value for a particular tire.
With and without "Mesage Center" respectively (pretty sure)
With the engine on...
Push "Setup" button, until your driver display says something like "Press Reset for system check".
Then push Reset. The system check will start, rotating through a series of checks.
About the fifth or sixth check will be the tire pressure. The system will sound the tone (same one that starts w/the light) and It'll say something like "Check Tires Pressure" on that moment press and hold for 3 or 4 seconds Reset. When you release the Reset button It'll show "Hold Reset if tires are OK". While that's up, hold the Reset button. After 3 or 4 seconds, the tire warning light will blink 2 or 3 times and then will stop .You need to be ready for it, because you don't get very long to release.
How to reset the low tire pressure warning if the vehicle does not have the "Message Center"
Turn the ignition to the ON position, depress and Trip/odometer button (located in the instrument cluster) until "TIRE RESET" or "CHECK TIRE AND RESET" is displayed in the odometer display window. Once "TIRE RESET" or "CHECK TIRE AND RESET" is displayed, press and hold the button for three seconds. The low tire warning indicator light will flash three times as the low tire warning system begins to initialize.
Firestone Hmmmmmm. Well the reset button is located just under the dash to the left of the steering column, hold for a few seconds and the light should go out. Hopefuly the firestone tech won't tell you your brakes need greasing the next time you go in for service, haha. Oh, I do beleive your tire pressure should be 29 psi. But, you can check your owners manual for correct pressures. It sould also tell you where the reset button is also. That should FixYa good luck.
i would check the tires first to make sure they are properly filled you should have around 40lbs or so keep in mind that as u drive the tires heat up which causes air to expand, and when they cool the air will shrink also check valve stems make sure they arnt leaking spray some windex on them see if u see air bubbles coming out or not. if u are low on air would recomand filling the tires up at night when its cool out air is more dense when its cool then hot will help keep your tire pressure from fluctuating as much or you can look into getting the tires filled with nitrogen. i dont think there is a way to turn that light off you can try the same way u reset the oil light on that car put key in on position press gas three or five times cant remember then start the car see if it flashes and goes off dont worry u wont flood the motor its electronic fuel injection let me know if this helped u any
Have you driven the vehicle over 45 mph.? If not, drive 5 miles above 45mph and the light will reset. You can also clear clear pressure reading by reseting through the DIC, mode and set buttons. Owners manual will explain use of the DIC ( Driver Information Center) Good luck, let me know. Regards,
this would be a low tire symbol have you tire pressure check it will come on when one off your tires get a little low. the light will reset itself after the proper tire inflation is put in ..thanks for choosing fixya
