You guys are having issues with one of your sensors not reading. The beep happens when low pressure is detected, the light after sustained driving with no beep happens when the system can't detect one or more sensors.

OK here's how it goes, a blinking light on dash means sensor is bad or there is a problem in the receiver in the dash. With a solid light it means you are low on pressure by at least 25%.
TPMS can be reset to any desired pressure that you want to program into the computer. Once you do that it will go off if you are 25% below that setting.
If you have a light going off & it's not low on air you need a tpms tool to test the sensors & then do a reset thru obd2

Subscribed. I've had a tempermental TPMS light the last few days, too.
Went off the other night after work with the beep. Stopped the car, checked the air, all the tires were inflated to 35 PSI.
Pumped them all up to 40, TPMS light went off. Today, driving, it goes off again with the same beep. Stop, check all tires, still good on pressure. So I'm not sure if one of my sensors is going bad, or the change in weather is messing with them.

I just took my car on a very very long road trip and found that the tpms light kept coming on after I would drive for more than about 1 hour. Whenever I checked, the pressure was between 35-38 psi. I assumed the tires were over-inflated, but now that I am reading this, I guess I might be up for new sensors... 2004 here with just over 90K miles. I guess nothing lasts forever.

Honestly, these TPMS are ridiculous. They're just one more thing to break on the car. I can check my tire pressure the old fashioned way.

yes you can check pressure the old fashioned way, if everyone was intelligent & capable of doing that Ford/Firestone would never have had a problem, & tpms would not exist.
Nissan recently came out with a system on some of their 2013 cars that when you reach desired pressure when filling the tire that the horn beeps so you know it is ok without checking.
Whether you like it or not tpms is here to stay & in some states is mandated to be in working order to pass inspection. Overall it is a good thing but people & shops have to understand it in order to diagnose & fix or replace them. At my place we have been doing tpms for over 20 years & we are pretty good at it but still run into headaches.
We did find out that most dealers fix all problems by changing parts not diagnosing problem & they will usually blow you off if you have custom wheels on when a sensor goes bad.
