| DTC Strategy |
- Check operative readiness
- Controller Malfunction - Gain / Offset
- 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 (1,202°F)
|
| Threshold Value |
- O2 sensor Element Resistance > 2100 Ohm
|
| Diagnostic Time |
|
| Fail-Safe |
- EVAP. emission control function is controlled in minimum operation mode
