To clarify, in order to replace the fuel tank pressure sensor to fix codes 0451 and 0452 you had to replace that entire harness? I'm trying to help my aunt with her 2011 EL XLT. She paid a shop to replace the pump and then started getting those codes. Do you have apart number you might be able to share?
Its not a wiring harness its a assembly of plastic lines that are molded onto the sensor. Ive been trying to find the part number myself for about an hour but Ill try again tommorow at work. I shouldve added the part number at the time, sorry 😅
