| DTC Strategy |
- Evaluate O2 sensor element temperature via measuring element resistance
|
- Related fuse blown or missing
- Heater control circuit open or short
- Power supply circuit open or short
- Contact resistance in connectors
- Faulty HO2S
|
| Enable Conditions |
- Sensor preheating and full heating phases finished
- Time after start elapsed : 240 sec.
- 11V < Battery voltage < 16V
- 1 % < Heater power < 99%
- Exhaust gas temp.model < 650°C (1202°F)
- No relevant failure
|
| Threshold Value |
- O2 sensor Element Resistance > 2100 Ω [Element Temperature < 500°C (932°F)]
|
| Diagnostic Time |
|
| Fail-Safe |
- EVAP. emission control function is controlled in minimum operation mode
|
| Mil On Condition |
