When your Ford Explorer displays the OBD-II fault code P1450, it means that the EVAP running loss monitor has detected excessive vacuum in the fuel tank when the engine is running, but not idling. This information is sent to the powertrain control module, triggering the check engine light. There are several potential reasons for this issue, with varying costs involved. It could be due to a fuel filler cap that is stuck closed, hindering vacuum release. Another possibility is a kinked or damaged hose between the EVAP canister and fuel tank. A defective fuel tank pressure sensor or a blockage in the EVAP canister or vent solenoid are also potential culprits. It is recommended to start your diagnosis at these points and proceed with the necessary repairs based on your findings.

The code p1450 indicates an issue where the fuel tank cannot release its vacuum, and this problem is not related to the fuel pressure sensor. Instead, the main cause is often a faulty sensor in the fuel tank pressure system.
