Diagnostic boundary
A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.
Do not replace the EGR valve until feedback wiring and mechanical sticking are both evaluated.
Useful checks before replacing parts
- Compare commanded EGR position with feedback position while the valve is commanded through its range.
- Inspect valve sticking, carbon buildup, connector condition, reference voltage, ground, and signal integrity.
- Check related MAP, idle, and drivability data because EGR performance faults often affect engine response.
