As an American, I would say: The 2016 Ford Fiesta may display various codes and warning lights on the dashboard throughout the years of ownership. It's important for drivers to understand the meanings of these codes in case there's an issue. For instance, if code p450 appears, it indicates that the gas tank is unable to create the necessary vacuum within itself. This particular code is unique to Ford vehicles. The powertrain control module (pcm) detects excessive vacuum levels either in the gas tank or the evaporative emissions (evap) system. This problem could be due to a blockage in the evap system, a faulty tank pressure sensor, a kink in the hose connecting the evap canister to the gas tank, or a fuel filler cap that is stuck.
The p1450 error code on the 2016 Ford Fiesta indicates a problem with the fuel tank pressure sensor (FTP), causing the fuel tank to not vent properly.
In 2016, the Ford Fiesta's P1450 code indicates that there is an issue with the fuel tank's ability to release built-up vacuum pressure.
