- Poor connector connection
- Open or short circuit
- HO2S (Bank1, Sensor1)
- HO2S (Bank1, Sensor2)
- Fuel system
- Intake system
- Injector

| Enable Conditions |
- 12V battery voltage (11 to 16V)
- The temperature of the upstream oxygen sensor tip is higher than 800°C (1472°F)
- When the upstream oxygen sensor heating time is higher than 30 seconds, it is in the maximum heating or normal heating state
- When the injector is operated, the intake air amount is higher than 50g
- The difference between the actual engine speed and the filtered engine speed is less than 80 RPM
- When the difference between the engine torque value and the filtered value is less than 120Nm
- When the difference between the actual value of the engine intake air volume and the filtered value is less than 0.25 g/rev

| Threshold Value |
- Oxygen sensor (B1S1) lambda value is higher than 1.1 (lean)
