Code P1408 2002 Ford F150 Description

The P1408 diagnostic trouble code (DTC) for a 2002 Ford F150 indicates that the Exhaust Gas Recirculation (EGR) system is experiencing a flow that is outside of the self-test range. The EGR system plays a crucial role in reducing harmful emissions by recirculating a portion of the exhaust gases back into the engine's intake manifold. This process helps lower combustion temperatures and reduces the formation of nitrogen oxides (NOx) in the exhaust.
