If I am getting a TPMS Sensor Fault message (and the icon flashing on instrument panel), will I need to replace all four sensors? Vehicle is a 2005 EB.
 






Theory 1: They are battery operated and 11 years old. Have you ever heard of a battery with over 10 years of shelf life?
Theory 2: You can try to, "train" them with the magnet and the chirp thing and see which one(s) don't respond.
