Code P2465 Dodge Description

The P2465 code for Dodge vehicles indicates that the Diesel Particulate Filter (DPF) Differential Pressure is too high in Bank 2. This means that there is a significant difference in pressure before and after the DPF in the exhaust system on the second bank of the engine. The DPF is designed to trap and remove harmful particulate matter from the exhaust gases to reduce emissions. When the pressure differential is too high, it suggests that the DPF is becoming clogged or restricted, impacting the vehicle's performance and emissions control system.
