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 charcoal canister for a purge valve circuit code; start with the purge solenoid electrical path.
Useful checks before replacing parts
- Check purge valve power, ground or control circuit, connector condition, terminal tension, and harness routing near the engine.
- Command the purge valve with a scan tool if available and compare electrical response with actual purge flow.
- Review EVAP leak or flow codes because purge circuit faults can prevent normal monitor operation.
