Did you have the P0453 before you replaced the fuel tank?

Just the fuel tank
Expert:  A. Penland replied 1 year ago.

The FTP (Fuel Tank Pressure) sensor is on top of the fuel tank. It has an electrical connector that is part of the harness that plugs into the fuel pump. It is a square sensor molded into the plastic hoses for the fuel vapor lines.

Since you had this code before the repair, replace the FTP sensor and tube assembly. See below.

Did their is any fuse for the ftp?
Expert:  A. Penland replied 1 year ago.

No, make sure it is plugged in completely. You may have to take the rubber ring seal out of the electrical connector to make sure it fully locks onto the sensor. Once you connect it, you should not be able to remove it without pressing the release tab.
