On my 2009 Silverado LTZ, I have read outs for tire pressures....The other day I happen to notice that the front right tire was reading zero, although it looked fully inflated....So, I knew that was not the case...Googled the problem on the net and found I had to reset the computer, using these procedures:http://www.silveradosierra.com/how-...erra.com/how-to-articles/how-to-reset-your-tpms-after-rotating-tires-t4022.html

Have anyone ever seen something so crazy?

 

[Chevyragtop57]

Good to know. I do not have anything that new to be aware of this. Thanks for the info. MIke

 

[Talldeck427]

Yeah. I had to teach the sensors on a 07 tahoe after replacing all 4.

Computers!

Hey David at least you were able to reset it yourself (yay internet!). Some imports have to go to the dealer for that.

I bet TPMS, a good thing for safety and tire life, and mandatory at least as a basic system starting in 2008, is a royal headache for tire stores.

Actually, I have not gone through the procedures yet....I called my guy and he can check the sensor to see if it is working, when I bring it in next time for its next oil change....He tells me that the valve stems have sensors with a battery to transmit the info to the computer.

I was told the battery is only good for 5 to 7 years and are not replaceable. You have to replace the entire sensor. At $60 to $100 each parts and labor.
I have a 2009 F150 and have them going bad now. Trying to decide if $400 is worth the expense that to turn off a warning message. I check my tire pressures at least monthly when I check all of the fluid levels.
I have also had to reset the trucks CPU once. Not hard to do with all the you tube instructional videos. :shakehands::anim_25::flag6:

 

[mickeywestsr]

Mine never read zero but lotsa time show "low." ..... :anim_25:

Took the truck to the store today....The problem seems to have resolved itself....The tire pressures are all normal....We'll see.

Just don't break the monitor inside the rim, it'll cost you a bunch, then another bunch to have the dealer re-program the monitor to your car. I had one that I lost the black plastic cap and grabbed a go-fast chrome one I had. Bad idea. The chrome one seized to the stem and broke the stem trying to remove.

Amazon.

You have to replace the entire sensor. At $60 to $100 each

I have acquired on two occasions an OEM sensor from Amazon for approx $40 each. On one, I had to have the tire bead broken off one side of the rim to get the specific manufacturer part number. There is much good info to be had on Amazon by locating your sensor, then reading the customer feedback for that part. If it fits your application (or doesn't), it's likely someone has written about it.

One sensor I replaced was user programmable.

Another good reason to buy old cars.......

TPMS woes

I too have had several vehicles that have had the TPMS and quite frankly, they are a pain in the butt.

Although the sensors themselves are not very expensive,( here in my part of the country the GM ones are about $40.00 each, ) by the time you have them installed and then have the tire shops proper "machine" to link them to your computer system, you are out quite a few bucks.

To me this is just another example of an overload of unreliable gadgetry that the new car manufacturers like to load onto vehicles these days
I am all for things that make the new cars safer, but realistically , these monitors result in a lot more money spent at tire shops and dealerships ,than
preventing serious tire problems.

I suppose that if you are not in the habit of regularly checking your tire pressures they could alert you to an underpressure situation in time to save a tire, but my experience has been either they trigger when you have a puncture and , if you have a drivers license , you should know when you have a flat tire !! or they trigger false/positive i.e. for no reason..

Just my 2 cents worth,..... adjust for inflation and poor Canadian dollar and it works out to....$1.49

haven't bought a new car in over 12 years. sounds like lots of expensive stuff to have to fix. :banghead:

Can't blame the OEM's for this one, the government mandated it on vehicles from 2008 and newer. Wheel and tire stores are required by law to install them on those model years. They can be a pain but they do have some safety value also, especially here in the winter when's its cold and your tires lose air. The newer vehicles are getting easier to reset than older vehicles,

 

[wagzilla]

I have a tpms machine and I like it, tell you the shape the battery is in I can rotate tire no problem tells me how your key fob is working, how good the battery is, I can put in new tire sensor and program it. battery life is about 7 years. I do like oem sensors.

pressure

I have replaced all 4 on my 09 F 150 w/ 140k. Now have another one bad. Not fixing again!!!!!

 

[duke57]

I hate TPM's. There are no need for these extra sensors which are causing problems. They already have the ABS sensors (which can be troublesome) but the ecm could use to calculate the tire pressure based on rpm's. The tire size rotates at a particular rpm for a particular speed. If the rpm's vary that indicates tire is not properly inflated. They are just money makers for service depatments.

 

[DavidY]

My sensors are factory set to trigger at 31 psi. I like to run 33-34 psi so rarely have a problem except in the winter. When it gets cold the pressure often drops just enough to trigger the light but driving it raises the tire temperature. Then just turning the ignition off and on a few times resets the monitor. If you have 65-75 series tires the sensors are relatively worthless - you can see or feel if your tire is low. Their value is if you have 21" wheels and rubber band tires where it's nearly impossible to see a flat tire by looking at it.

 

[oakesr1]

I have a 07 Avalanche that throws a fit like that every so often. If you wait it out it will reset itself.
