Does anybody know how the onboard tire pressure system works?
Is there a sensor in the rim,tire,or what?
Just curious.

Read page 308 of the owners manual. The CAUTION part of that page. It does not state if it is within the valve or within the inner part of the rim. It also states that aftermarket wheels can damage the pressure sensor.

Thanks! We also need to replace the right rear tire (small nail on sidewall) and want to let the tire store know it has tire pressure monitoring system.

This feature also saved my butt this week when I was the lucky winner of a left/rear inner side wall puncture/tear... alarm sounded and I was off the road in under five seconds (where I watched the pressure go from 35 psi to 4 in an instant). Had I not had that alarm and been driving at full speed when the main tear happened, it would have been UGLY.

BTW the tires for the R/T are almost impossible to get right now (too new is the story I got at every tire place in town) and very expensive ($265+ list if you can even get one).... luckily my dealer pulled one from a vehicle while he ordered a replacement and split the cost with me as the vehicle was only three weeks old (and spent one of those weeks in the shop tracking down a front end noise).

A friend just bought a 2008 avenger, and her tire pressure monitor blinks everyday, we're assuming because of the nitrogen tires. After she has been driving for about half an hour, and the tires have warmed up, the monitor goes off. How is she to know if she ACTUALLY has a tire pressure issue, and is it safe to drive it while this is going on? Thanks!

If you don't trust the tire pressure monitor then you can go out to the store and pick up a cheap pressure gauge and check the tires to see if the pressure is correct in comparison to the car's gauge..
Chances are the tires (or one tire) are a little low on air causing the sensor to trip, then after she drives the tires heat up which causes the air in the tires to expand bringing the pressure up to acceptable levels.
I would assume that there wouldn't be any issues if she continued to drive on the tires the way they are now as long as they are not visually flat but I would check the air pressure and fill any tires that are low.

The tire monitor reads transmitter thats part valve stems and there is a battery as well with the transmitter, Each transmitter has a serial number that the monitor ck's. So if the battery goes dead the monitor will give a low tire message. The tire pressure transmitter have a 10 year warranty.

Excellent information. I didn't know there was a battery.

There are what are usually called TPMS sensors in each wheel. Fords current setup is banded to the actual wheel, whereas most if not all other companys are part of the valve stem. I've not personally torn down a dodge wheel to see but usually the "stem" is just attached to the sensor, its not part of the sensor. All the sensors have small 3v batterys in them and are designed to last a long time before going bad. The reason for this is at a steady non rotating state, the sensor will either stop transmitting or only transmit like once every 6 hours or something. Somewhere near each wheel well there may be a reciever, but this is based on what company is making the sensors for dodge.
I suspect that climate changes may be what is causing one of the other posters here friends tpms to trigger. I know myself that when the weather here got colder mine triggered. The reason is, when the tires or the air inside the tires is cool, the pressure is lower. When its hotter, the pressure is more. All thats needed is to put a bit more air into them.
I wouldn't be surprised if a sensor went bad...it does happen. Normally though, its a result of tire repair, where the tech doesn't know about the sensor and breaks or damages it when replacing a tire. Or a tire goes flat and is driven on for a few miles and that causes the damage. Aftermarket wheels really won't damage a sensor unless they are removed from the original wheel improperly or installed improperly. Its just there so they can point to it when you bring it in for a warranty repair. And if you get aftermarket wheels and don't switch the sensors, the system will trigger. It won't hurt anything, but you will have to deal with the annoying nag lights and such.
