Now it was not on because my tires were low, I have an aftermarket monitor that shows my actual tire pressure. It was on because my spare was stolen out of the bed of my pickup last year, and the light was to let me know one of my TPM were not connected. I picked up a new spare off Craigslist list shortly after mine went missing, but I never got it connected to my trucks monitor, but this morning the light that normally flashes for a minute then goes solid… never came on.
I took the spare out of the bed for two day’s and nothing changed with the light. But yesterday while driving to the next town up for a vet appointment, about 30 miles into the drive the TPMS light flashed for 1 minute then stayed on like it should when a sensor is missing, it appears to be working fine again.
Fascinating. Thanks for the update
