Check engine light came on and the shop said it's fuel tank pressure sensor that needs changing.

Good afternoon,

I attached a picture and a procedure for replacement. The sensor is located on the fuel pump module. The fuel tank has to be removed to access it.

What is the code that led them to this diagnosis? This is a rare failure.

Removal Procedure
Note: Clean the fuel and evaporative emission (EVAP) connections and surrounding areas prior to disconnecting the lines in order to avoid possible system contamination.
