P1406 Dodge Code - EGR System Pintle Position Error

Quick Answer

The Exhaust Gas Recirculation (EGR) valve recirculates exhaust gas to the engine intake for increased efficiency, lower fuel consumption, and reduced NOx emissions. Common causes include Faulty Exhaust Gas Recirculation (EGR) Valve, Faulty Exhaust Gas Recirculation Valve Solenoid, Exhaust Gas Recirculation valve carbon blockage. Severity is Moderate - service should be scheduled soon. The vehicle may still be drivable for short trips if it runs normally, but avoid hard driving and repair it soon.

Code P1406 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.
