| DTC Strategy |
- Check fuel tank pressure during evacuation
|
- Leakage in each hose/fuel filler pipe (leak or stuck)
- Leakage in CCV/canister/fuel tank/fuel filler cap
|
| Enable Condition |

- Time after engine starts has passed 100s
- Barometric pressure (BARO) is greater than 75 kPa
- Canister load is less than 0.35
- Minimum canister purge time is greater than 3s in case of canister load is less than 0.1
- Minimum canister purge time is greater than 25s in case of canister load is greater or equal to 0.1
- Engine speed is lower than 1500 to 1650 RPM
- Gas pedal value is lower than 0.01% (Pedal is not pushed at all)
- Differential fuel tank pressure is between -1100Pa and 400Pa
- Vehicle speed higher than 22.5 km/h (14 mph) at least 60s
- Time since last EVAP monitoring test abortion is longer than 60s
- Barometric pressure gradient is less than -2.0 kPa during uphill driving within 5 ms
- Time elapse in case of refueling identification is greater than 600s

| Threshold Value |
Case 1 |
- It takes more than 20s to make the fuel tank pressure below the -1600Pa
|
| Case 2 |
- It takes more than 10s to make the fuel tank pressure above -300Pa and below 700Pa
