- P0441 (Evaporative Emission Control System Incorrect Purge Flow)
- P043E (Evaporative Emission System Reference Orifice Clog Up)
- P043F (Evaporative Emission System Reference Orifice High Flow)
- P2401 (Evaporative Emission System Leak Detection Pump Control Circuit Low)
- P2402 (Evaporative Emission System Leak Detection Pump Control Circuit High)
- P2419 (Evaporative Emission System Switching Valve Control Circuit Low)

Production changes have been implemented to prevent this condition from occurring.
