Code P1405 Dodge Description

The Exhaust Gas Recirculation (EGR) valve recirculates exhaust gas to the engine intake for increased efficiency, lower fuel consumption, and reduced NOx emissions. The valve changes the air's chemical makeup by adding exhaust gas, which dilutes the mixture and lowers combustion temperatures, resulting in less NOx production. The valve has two primary settings: open and closed, depending on the engine's power requirements. EGR valves can also improve combustion efficiency, reduce pumping losses, and decrease diesel knock at idle.
The Diagnostic Trouble Code (DTC) will be set when the Engine Control Module (ECM) detects EGR flow or movement when it is not expected.
