P0404 on Chrysler vehicles indicates exhaust gas recirculation circuit range/performance. Au7o has documented this code across 3 Chrysler models — most commonly on Crossfire, PT Cruiser, Sebring. 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 Chrysler range from $150 to $2,000, 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)

P0404 on Chrysler by Model

Chrysler Crossfire(1 issue)

  • EGR Solenoid and Catalytic Converter Failure2004-2008

    The Crossfire (built on Mercedes SLK R170 platform, sharing 80% of components) commonly experiences EGR solenoid failures and premature catalytic converter failure. The EGR solenoid is the most common cause of check engine lights. Catalytic converter rattles and fails, especially noticeable when accelerating from cold.

Chrysler PT Cruiser(1 issue)

  • EGR Valve Failure and Carbon Buildup2001-2010

    The EGR (Exhaust Gas Recirculation) valve on the 2.4L engine clogs with carbon deposits and sticks open or closed. When stuck open, it causes rough idle, stalling, and hesitation. When stuck closed, it increases NOx emissions and may trigger a check engine light. The EGR passages in the intake manifold also clog with carbon, reducing effectiveness even with a functioning valve. The turbo model is especially prone due to higher exhaust temperatures.

Chrysler Sebring(1 issue)

  • Alternator and PCM-Integrated Voltage Regulator Failure2001-2010

    The Sebring's voltage regulator is integrated into the PCM (Powertrain Control Module), not the alternator. This unusual design means a voltage regulator failure requires PCM diagnosis/replacement rather than simple alternator work. Alternators also fail prematurely around 70,000 miles. Ground corrosion and battery terminal strip issues compound the problem.

Frequently Asked Questions

What does P0404 mean on Chrysler?▼

P0404 stands for "Exhaust Gas Recirculation Circuit Range/Performance." 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. On Chrysler specifically, this code is documented across 3 models.

What causes P0404 on Chrysler vehicles?▼

Common causes on Chrysler: 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. Specific causes vary by model and year — see the per-model sections below.

How much does it cost to fix P0404 on a Chrysler?▼

Repair costs on Chrysler range from $150 to $2,000, depending on the specific model and root cause.

Which Chrysler models have P0404 documented?▼

Au7o has documented P0404 on 3 Chrysler models: Crossfire, PT Cruiser, Sebring.
