P0404 on Dodge
Exhaust Gas Recirculation Circuit Range/Performance
P0404 on Dodge vehicles indicates exhaust gas recirculation circuit range/performance. Au7o has documented this code across 1 Dodge model — most commonly on Journey. This code means the exhaust gas recirculation (EGR) system isn't performing within its expected range. The EGR valve routes a metered amount of exhaust gas back into the intake to lower combustion temperatures and reduce nitrogen-oxide emissions, and the computer monitors the valve's actual position versus what it commanded. When the valve sticks, moves incorrectly, or the feedback doesn't match the command, P0404 sets. This can cause rough idle, hesitation, pinging, and increased emissions. Typical repair costs on Dodge range from $400 to $1,200, depending on the specific model and root cause.
Common Causes of P0404
- •Carbon buildup clogging the EGR valve or passages
- •Sticking or failed EGR valve
- •Faulty EGR position sensor
- •Corroded or loose EGR connector
- •Damaged or shorted EGR wiring
- •Vacuum leak or failed vacuum control (on vacuum-operated systems)
- •Clogged EGR cooler or tubes
- •Faulty PCM/ECM (rare)

- 3.6L Oil Filter Housing Leak2011-2020
Plastic oil filter housing on 3.6L Pentastar warps, cracks, and leaks due to heat exposure. Housing located under intake manifold, making leaks difficult to detect until severe. Heat degradation causes plastic to become brittle and crack.
