The TPS alarm in my car suddenly went off today while traveling down the freeway. My left rear tire was down to 20 psi. I quickly exited the roadway and found a tire shop about a block past the off-ramp. I assumed the tire was punctured but the failure was instead due to a leaking valve stem / TPS sensor. I'd never heard of this. I was more than happy to pay the $25 repair bill and was back on the road within 20 minutes. Sounds like this isn't terribly uncommon, but I attribute it to today's frigid 6 degree F temps.
