Code P1408 2006 Ford Fusion Description

The P1408 diagnostic trouble code (DTC) for a 2006 Ford Fusion indicates that there is an issue with the Exhaust Gas Recirculation (EGR) system. Specifically, it means that the EGR flow is out of the self-test range set by the vehicle's onboard computer. The EGR system is responsible for recirculating a portion of the exhaust gases back into the engine's intake manifold to reduce emissions and control combustion temperatures. When the EGR flow is not within the specified range, it can lead to various performance issues and potentially harm the engine.
