- Clogging, cracks, and poor connection of hose between check valve (ejector side) and ejector
- Check valve (ejector side) malfunction
- Ejector loose
- Ejector malfunction
- Check valve (intake manifold side) malfunction (stuck open)
- Malfunction in evaporative gas passage between fuel tank and purge solenoid valve
- Clogging, cracks, and poor connection of hose between fuel tank and fuel tank pressure sensor
- Clogging, cracks, and poor connection of hose between fuel tank pressure sensor and charcoal canister
- Clogging, cracks, and poor connection of hose between charcoal canister and purge solenoid valve
- CV solenoid valve malfunction (stuck open)
- Charcoal canister malfunction (worsening of airflow resistance, or other)
- Purge solenoid valve malfunction
- PCM malfunction
