Fuel tank pressure sensor circuit high can either mean an open circuit (broken wire) or a faulty sensor in most cases. Most of the time I find bad sensors for this code (99% of the time). I've attached pictures of the location on top of the fuel tank and is supposed to come with the entire assembly but they sell this sensor by itself online. I would start by inspecting the wiring at this sensor for cut or chafed wiring.F57Z-14A606-BA is the part number.
