The P1450 code on your Ford Fusion indicates that the system is unable to bleed off the vacuum in the fuel tank. I had this issue on my 2017 Ford Fusion, and while the car still ran fine, it would hesitate after refueling. This issue is often linked to the EVAP (Evaporative Emission Control) system, which manages fuel vapors to reduce emissions.
First, inspect the EVAP purge valve, which is located near the engine. This valve is responsible for controlling the flow of fuel vapors from the fuel tank to the intake manifold. A stuck or faulty purge valve can cause excessive vacuum in the fuel tank. If you find that the valve is stuck closed or open, replacing it should resolve the problem.
Next, check the fuel tank pressure sensor. This sensor monitors the pressure inside the fuel tank and can trigger the P1450 code if it’s not reading correctly. If the sensor is damaged or faulty, you’ll need to replace it.
You should also inspect the EVAP hoses and charcoal canister for any signs of damage, blockages, or leaks. A clogged canister or damaged hose can also prevent the system from relieving the tank vacuum properly. If everything looks good, test the fuel tank vent valve to ensure it’s functioning correctly.
Once the necessary repairs are made, clear the P1450 code with an OBD-II scanner and test the car to ensure the issue is resolved. If the code doesn’t return, you’ve successfully fixed the vacuum problem. If it persists, you may need to check the fuel filler neck for blockages or other issues that could affect tank pressure.
