Common EGR Fault Codes & Meanings
P0404 (EGR Circuit Range/Performance): The valve isn’t moving as expected.
P0400 (EGR Flow Malfunction): General problem with EGR performance.
P0401 (Insufficient EGR Flow): Not enough exhaust gas is recirculating (common with blockages).
P0402 (Excessive EGR Flow): Too much exhaust gas is recirculating (often a stuck-open valve).
P0403 (EGR Circuit Malfunction): Electrical issue in the valve’s circuit (wiring, solenoid).
Symptoms of a Faulty EGR System
- Illuminated Check Engine Light (CEL)
- Rough idling or engine vibration
- Poor acceleration or hesitation
- Engine knocking or pinging (especially under load)
- Increased fuel consumption
- Engine running hot
Common Causes

- Stuck EGR Valve: Can be stuck open or closed.
- Faulty Sensors: EGR position sensor or temperature sensor issues.
- Wiring/Circuit Problems: Damaged wires or connectors.
- Vacuum Leaks/Solenoid Issues: Affects vacuum-controlled systems.
