Chrysler Error Code P1404: How to Fix It

Q: What causes Chrysler P1404 error code?

P1404 is typically caused by a dirty or stuck EGR valve, faulty electrical connections, damaged vacuum lines, or carbon buildup preventing the valve from closing properly. In rare cases, a failing PCM can also trigger this code.

Q: Can I drive with P1404 code?

Yes, you can typically drive with P1404, but it may cause rough idle, poor fuel economy, and increased emissions. The vehicle should be repaired soon to prevent potential engine damage and to pass emissions testing.

Q: How much does it cost to fix P1404?

DIY repair costs $20-50 for cleaning supplies and gaskets. Professional repair ranges from $150-400 depending on whether cleaning or replacement is needed. EGR valve replacement typically costs $200-350 including labor.

Q: Will P1404 cause my car to fail inspection?

Yes, P1404 will typically cause your vehicle to fail emissions testing since it indicates an EGR system malfunction. The code must be resolved and the system must complete its readiness monitors before passing inspection.

Q: How do I prevent P1404 from returning?

Use quality fuel with detergent additives, perform regular maintenance, replace air filters as scheduled, and consider periodic EGR valve cleaning every 60,000 miles. Addressing intake manifold leaks promptly also helps prevent EGR issues.

Abstract

The P1404 error code in Chrysler vehicles indicates that the EGR (Exhaust Gas Recirculation) valve's closed pintle position has not been learned by the engine control module. This typically occurs when the EGR valve is stuck, dirty, or when there's a communication issue between the valve and the PCM.
