Tire pressure sensors - Page 2

I'll jump in this, similar scenerio happened with my 06 CC, around the 2k mark. I had low tire pressure, aired it up to 35 in rears and 35 in fronts... drove around for about 10 miles, the sensor never went away (supposed to reset once pressure is above min.) I took it in and the maintenance guru hooked it up and reset the entire TPS system, it works fine now... I'm not sure if they can adjust the min. setting for the TPS, if so, I will see if they can set mine for a lower pressure (thinking 20) before warning light activates so I can air down without it blinking or glowing steady...

Definitely something I am gonna look into more thoroughly. I have been postponing this purchase due to Christmas and other bills, but I want new rims by Spring.

1st:
If the malfunction light is on (with no beep, indicating a malfuction not a low pressure) and THEN a tire goes flat, will the system beep at you even though the light was already on? That would be nice to know and make the malfunction more palatable.

Secondly:
What could be the root cause of the error in the first place? Bad sensor? intermittent sensor? Poor signal reception from the tire to the reading system (keyless entry system right)? Low sensor battery? Bad computer / fault logic?

Mine has done the same thing with the light coming on after about 30 minutes of freeway driving. No Beep, just the light and it goes off after turning the truck off then on.
