It's cold here in Philly, decided to take the car to work and I got a TPMS system failure and it only shows me the left side tire pressures. As I continue to drive there is no indications, at a light I shut the car off and re-start to "reboot the system" and it come back on with just the left side again. Before I drive home I re-set it and it learns for 30 minutes then I get TPMS system failure warning again. The car is out of warranty, should I giggle a connector or something? If more than one tire sender is bad will the system think its failing? 3/4 of the senders are original 2007 vintage.
