| DTC Strategy |
- Check lambda signal amplitude - slow response
|
- Poor connection
- Faulty HO2S
- Faulty ECM
|
| Enable Condition |
- Upstream HO2S operative readiness is detected (Sensor tip temperature is greater than 680°C (1256°F) or heater maximum heating or normal heating for 30s)
- HO2S forced stimulation is active
- P042000 (catalyst diagnosis) monitoring is active
- P013300 diagnosis is synchronized with P042000 monitor
- Battery voltage is between 11V and 16V
|
| Threshold Value |
- Integral (lambda signal amplitude measured/lambda signal amplitude of a slow sensor) is greater than 1
|
| Diagnostic Time |
- 17 fuel trim controller cycles
|
| MIL ON Condition |
