Details of the Chrysler p0404 OBD Code
Chrysler fault code P0404 relates to an issue with the Exhaust Gas Recirculation Circuit Range/Performance.
Code P0404 for Chrysler vehicles indicates a fault with the Exhaust Gas Recirculation (EGR) Circuit Range/Performance.
This means that the EGR system is not operating within the expected range or is not performing as it should.
The EGR valve is the component that triggers this fault code.
The EGR system is involved in reducing nitrogen oxide emissions by recirculating a portion of the exhaust gas back into the intake system for combustion.
When the EGR valve or related components fail to operate correctly, it can trigger code P0404.
