The Lil' Rd Buggy was built in March, 2005. My TPMS system started giving indications of failure about 3 years ago, 2013. Age 8 years.
I found that all 4 sensors still work, but they have "drifted" upwards in median range. All of them.
They now will remain unlit if they are over 36 PSIG. And, yes, I checked them all. I was bored one afternoon.
How's about the rest of you?
