There is a problem in the fuel tank pressure sensor circuit.

No.

There is a separate pressure sensor for the Evaporative emissions system. It sounds like you need to find a local shop and have them troubleshoot the DTC's.

I would also maybe check your gas cap. That might be 1 reason, but it shouldn't cause 2 DTC's.

The fuel cap has nothing to do with an electrical fault of the FTP sensor.
