| DTC Strategy |
- Ignition timing reasonableness check during a cold start
|
- Intake systems limited
- The exhaust clogged
- Vacuum leakage
- Engine mechanical problem
- Carbon deposition at throttle body
- ETC system
|
| Enable Conditions |
- Catalyst heating (coolant temperature higher than -10°C (14°F) and lower than 33°C (91.4°F) at engine "ON")
- Above 5s after engine "ON"
- Vehicle speed lower than 60km/h (37mph)
- Accelerator pedal is less than 0.01%
- Target ignition timing efficiency is 0.8 during catalyst heating
- Diagnostic accumulated time is more than 5s
|
| Threshold Value |
- Ignition timing efficiency is higher than 1.5
