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 purge or vent parts before checking the high pressure-sensor signal and circuit integrity.
Useful checks before replacing parts
- Check for open grounds, short-to-voltage, poor connector contact, and damaged wiring near the tank or pressure sensor.
- Compare key-on EVAP pressure sensor data with expected baseline readings before running leak tests.
- Inspect sensor connector sealing, water intrusion, corrosion, and harness routing around the fuel tank.
