| DTC Strategy |
- Monitor the electrical signal
|
- Poor connector connection
- Open in signal circuit
- HO2S (Bank 1, Sensor 2)
|
| Enable Condition |
Case 1 |
- Battery voltage greater than 10V
- Temperature of the downstream HO2S tip is higher than 600°C (1112°F)
|
| Case 2 |

- Voltage of downstream HO2S between 0.4 and 0.5V for more than 3 seconds
|
| Threshold Value |
Case 1 |
- Resistance of the downstream HO2S element is greater than 131kΩ
|
| Case 2 |
- Applied pulse average voltage above 2.8V
