Detecting Condition |
Possible Cause |
| DTC Strategy |
- Front oxygen sensor response (signal amplification) check
|
- Poor Connector Connection
- Air leak in intake or exhaust system
- Faulty upstream O2 sensor
|
| Enable Condition |
- Coolant temperature is more than 73°C (163°F)
- Modeled catalyst temperature between 550 and 830°C (1022 and 1526°F)
- Vehicle speed is more than 3 mph
- Engine speed between 1300 and 3200 RPM
- MAFS signal between 0.3 and 0.9g/revolution
- Ambient pressure is more than 70 kPa (700 hPa)
- Canister load is less than 0.5
- Lambda control active & stable driving condition
- Downstream O2 sensor operative readiness
- No opening/closing of canister purge valve
- No relevant failure
- Battery voltage between 11 and 16V
|
| Threshold Value |
