| DTC Strategy |
- Check HO2S Signal Amplitude
|
- Leak in intake or exhaust system.
- Poor connection or damaged harness
- HO2S contamination
|
| Enable Conditions |
- Coolant temperature is higher than 55°C (131°F).
- Barometric pressure is higher than 760 hPa.
- Vehicle speed is higher than 5 km/h.
- Engine RPM ranges from 1300 RPM to 3300 RPM.
- MAF sensor value is between 150 and 450 mg/stk.
- Lambda control active
- Stable driving condition
- No relevant failure
- Battery voltage ranges from 11V to 16V.
|
| Threshold Value |
- Integral (Lambda signal amplitude measured/Lambda signal amplitude of a slow sensor) > 1.0
|
| Diagnostic Time |
- 22 lambda controller cycle
