Code P1455 Lincoln Description
When the P1455 diagnostic trouble code (DTC) appears on a Lincoln vehicle, it indicates that the Evaporative Emission Control System has detected a gross leak. This system is responsible for capturing and storing fuel vapors from the fuel tank, preventing them from being released into the atmosphere. A gross leak means that a significant amount of fuel vapor is escaping from the system, which can lead to increased emissions and decreased fuel efficiency. If left unaddressed, this issue can also cause the vehicle to fail emissions tests and potentially harm the environment.
