| DTC Strategy |
|
- Poor connector connection
- Open in signal circuit
- HO2S (Bank1, Sensor2)
|
| Enable Conditions |
Case1 |
- Fuel system status is no fuel cut-off
- Normal battery voltage (10 to 16V)
|
| Case2 |
- Fuel system status is no fuel cut-off
- Normal battery voltage (10 to 16V)
- Fuel system status is closed loop
|
| Threshold Value |
Case1 |
- Absolute voltage difference between high and low pins when is lower than 0.006V
- High pin voltage is lower than 0.7V
- Low pin voltage is higher than 2.5V
|
| Case2 |
- Downstream O2S voltage is between 0.415 and 0.515V
