If you have a 2016 F-150 and are dealing with a check engine light, specifically with the code P2450 related to the evaporative emission system switching valve performance stuck open, here’s a guide to help you troubleshoot and fix the issue.
Firstly, locate the sensor and valve on the far driver’s side of the gas tank. The valve should normally stay open, allowing airflow through it. However, when power is applied, it should close the valve.
To test if the valve is working, apply power directly to it. Ideally, you should hear a clicking sound as the valve opens and closes in response to the power. If there is no response, it verifies the issue of the valve being stuck open, leading to the check engine light.
Once the problem is identified, it’s necessary to replace the faulty valve. The replacement part can be obtained from the dealership, although it may come at a significant cost. After installing the new valve, ensure that it responds correctly to the power, emitting the expected sound, indicating its proper functioning.
Finally, clear the error codes, and the check engine light should no longer be illuminated, indicating that the issue has been successfully resolved.
By following these steps, you can effectively troubleshoot and fix a check engine light related to the evaporative emission system on a 2016 F-150, ensuring the proper functioning of the vehicle.
