both my 2005s have no problems, but the batteries in the sensors are 10 years old now
they won't last forever
i'd try disconnecting the (under the hood) battery for 1/2 hr, see what happens
it does take driving in a reasonably straight line for a period (check the owners' manual) to reset the TPMS system after a pressure warning episode
also, you're aware of the dreaded radiator/transmission failure potential, right?

yea thank you..I am aware..and the lines are already to an auxiliary cooler..not through the rad..
so disconnect battery..?
I have no idea when the batteries were changed in each sensor...is that a big job other than tire on and off?

sometimes a battery disconnect will re-set a system
the batteries in the sensors are not replaceable or rechargeable
if they go bad, the whole sensor will need replacement

The TPMS sensor batteries last about 6-7 years on average. If they are about that age or older and your code is set due to a low battery, then it makes sense to replace all four sensors. I always go with Dorman direct-fit TPMS sensors from Rockauto.com. They sell for about $40 each and have a lifetime warranty. The tires have to be dismounted to install them, so if the tires don't have a lot of tread on them left, it makes sense to replace the sensors when you replace the tires. The sensors will need to be "woke up" with a TPMS trigger tool and then registered to the TPMS controller. This can be done easiest with a capable scan tool, or by using the diagnostic connector reset procedure.
