Code P1404 Dodge Description

The P1404 diagnostic trouble code for Dodge vehicles indicates an issue with the Exhaust Gas Recirculation (EGR) Position Sensor system. The EGR system is responsible for recirculating a portion of the engine's exhaust gases back into the intake manifold to reduce harmful emissions.

  • Unfortunately, other than the EGR valve I have not seen any other component setting the P1404 code. I checked a national database of repairs for the same code, and couple of techs reported that, besides the valve, they also had problems with the EGR valve gasket. I hope that helps.
