The error code P1450 on the 2016 Ford Fusion points to a problem with the fuel tank's vacuum system, usually stemming from issues with the purge valve or EVAP solenoid. Owners often notice issues with the capless gas tank setup. Any damage or blockage in the system can lead to compromised tank venting, triggering the P1450 error code. Other possible culprits include a collapsed hose between the canister and fuel tank or a malfunctioning Fuel Tank Pressure (FTP) sensor, which is a common occurrence in the Fusion. If the gas cap is stuck closed, it can result in irregular pressure and vacuum problems. The average cost to replace the FTP sensor in the Ford Fusion typically ranges from $350 to $410 for parts and labor.
In a 2016 Ford Fusion, if you see error code P1450, it indicates that the fuel tank is having trouble releasing the built-up vacuum pressure. The primary reason for this code is often a faulty fuel tank pressure sensor.
