I had Titan TPMS sensors installed in Acura winter wheels on my 2013 TL in October. They never did work! I replaced them with Eon sensors which didn't auto-learn so I had the bar-tech tool method attempted twice. Still the CHECK TPMS display was on. The car was used daily, sometimes in excess of 200 km. Twelve days later, a month ago, the system started working and has ever since. Does anyone know what would cause this? I'm wondering if all is well now or if the system might quit just as abruptly in the future.
