There are a few:
- Pinched, blocked or plugged fuel vapor tubes/hoses
- Damaged EVAP canister
- Disconnected, cracked or cut fuel vapor tubes/hoses
- Damaged EVAP canister purge valve
WIth the engine running, open the hood and listen for a hissing sound that could indicate a leak. Also, check for fuel smell in the engine compartment or near the EVAP canister.
