| DTC Strategy |
- Check HO2S Signal Amplitude
|
- Poor connection
- Leak or clog in intake air system
- Injector
- Fuel pressure
- Faulty HO2S (Sensor1)
|
| Enable Conditions |
- Upstream O2 sensor operative readiness detected
- O2 sensor forced stimulation active
- P042000 (catalyst diagnosis) monitoring active
- P013300 diagnosis is synchronized with P042000 monitor
- Battery voltage is higher than 11V and lower than 16V
|
| Threshold Value |
- Integral (Lambda signal amplitude measured/lambda signal amplitude of a slow sensor) is higher than 1.0
|
| Diagnostic Time |
- 20 fuel trim controller cycle
|
| MIL ON Condition |
