Carefully insert the taped-up battery back into the sensor housing, but do not yet insert the main board into its correct location in the housing. Only once the battery is properly seated should you insert the main board back into the housing. My 2013 Outback TPMS light went on - after some confusion it appears the battery is low on one tire. Typically these batteries last a lot longer than 4 years so I'm wondering if this is just a one off issue or whether I should replace the sensors in all four tires. Anyone else have this issue...
