P2413 — Exhaust Gas Recirculation System Performance
The ECU monitors EGR flow indirectly through MAF, MAP or differential-pressure feedback and finds that actual EGR flow does not match the commanded value over a sustained period.
General code reference. Confirm the definition and diagnostic procedure for your vehicle's year, model and engine. A stored code alone does not identify a failed part.
Affected components
- Egr valve
- Egr cooler
- Egr diff pressure sensor
Possible causes to check
These are possible checks, not a ranked diagnosis. Follow the vehicle manufacturer's test procedure before replacing parts.
- Carbon buildup in EGR passages
- Sticking EGR valve
- EGR differential pressure sensor fault
Diagnostic notes
- The malfunction indicator lamp may illuminate
- This code can affect emissions
- A drive cycle may be required after repair
- Reduced-power or limp mode may occur

Check each reference's vehicle and model-year scope. General background links do not establish which fault is most likely on your vehicle.
Diagnostic information is provided for reference only. Confirm the code with a compatible scan tool and follow the vehicle manufacturer's service procedures before replacing components.
