How do you fix PO453 diagnostic code on 2007 Ford F150?

The PO453 diagnostic code on a 2007 Ford F150 indicates an issue with the evaporative emission control system, specifically a high voltage detected at the EVAP pressure sensor. To fix it, start by inspecting the wiring and connectors leading to the EVAP pressure sensor for damage or corrosion. If the wiring is intact, test the sensor itself for proper function and replace it if necessary. Additionally, check for any leaks in the EVAP system, including hoses and the gas cap, and repair or replace any faulty components.
