Tire pressure monitors have been required on cars since Sept. 2007 so yes you have them and they are not an option. If you have the tires rotated the tire shop will know what to do about reset.

 

Most are location specific and require a process to place them back in operation.

I've never seen or heard of one that is location specific. If there are any it's an extremely poor design. What vehicle have you seen them on.


All cars since 2007 have been required to have TPMS. Some companies actually put it in their vehicles sooner. My 05 4runner had it.


Some of these systems are not created equally. The one on my 4runner, wifes 07 Lexus and the Highlander just warn you that one of the tires is low, but doesn't tell you which one, other systems will actually tell which one is low. BTW - it could also be the spare that is giving you a low tire pressure warning.

 

"I've never seen or heard of one that is location specific. If there are any it's an extremely poor design. What vehicle have you seen them on."

Many sensors have to be "relearned" by the car as to what location they are at, especially those that give an actual tire pressure reading. If you have a tire moved from the left front to the right rear, you have to reset the system to read it at the correct position. If not and the tire goes flat, your warning will show it for the left front tire, even though it is now the right rear tire that is flat.

Not an extremely poor design at all, since you actually know which tire location is low on air. Many GM and Fords have hand held "tools" you can buy to reset the sensors if you rotate the tires yourself. Dealers should do the reset when they do a tire rotation as part of the rotation. Some vehicles allow you to reprogram the sensor locations through the dashboard instead of needing a tool.

As an engineer with over 30+ years experience that's a screwed up design. They are tying the location information to the tire instead of the sensor that reads the pressure from the TPMS. If the sensor had the location built in you'd never need to worry about reprogramming thing because of a simple tire rotation.

in Owners Manual pg 570 section 8-2

As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS-tire pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated.

so yes, your XLE has sensors.
As for "location specific" and "resetting when tires are rotated".....that should not have to be done if that year is like our 2017. The sensors have their own unique ID stamped on the sensor. It's a little work determining which sensor is on which tire but with Techstream, life becomes somewhat simpler in finding that out.

 

Thanks for the info. Chevrolet Impala and Corvette ( 2004 and up ) have to be reset with a specific tool to " learn their correct location ". My friends 14 Impala requires a specific electronic device to reset them. ( only $86.00 ) The dash will tell you which tire is below the set pressure.
I like doing my own maintenance . Tire rotation gives me a chance to check the pads, rotors , and inspect the tire surface. Aside having a new Rotary lift to play with, ..... its fun !

 

These vehicles do not know where the tire is located, and you don't need to do ANYTHING when you rotate them.
I know the TPMS system very well on these vehicles.

You can see this video I made on how to replace a sensor and reprogram the ECU.

One of the most powerful tools, even before the TPMS that you can use to tell which is low is your eyes. If you are trying to be accurate, the other amazing tool is the pressure guag...Thanks to Eugene Bourdon the Frenchman who invented the guage to measure pressure, many other guages followed, and now have a device you could put in your glove box. The TPMS is also great if you don't look at your tires as a general practice as you approach your car. The other function we DON'T have is the units in PSI of how much the tire has lost air. This would be great to call up, or display at startup, to help keep your tires at the needed pressure more regularly.
So this feature we have is very limited to maybe a nail or something that is causing loss of air at a abnormal rate. Otherwise a blowout will be pretty much too late anyway, but I guess an added indication on the dash should get your attention right away.

 

Impressive video. Research did find the sensors were non location descriptive on the HL. Not having the Corvette here I was told the dash display will tell you the tire location at fault. Not being a tech wiz I read and mostly understand some computer functions. If not laid out in a format I get lost some where usually. I might be the " pick and shovel " guy when it comes to technology. Common sense guides my highway more than programming.
