Secondary Parameters And Enable Conditions
Additive adaptation learning area and multiplicative adaptation learning area:
Enable Conditions:
- Closed Loop Active
- Application conditions fulfilled
- Fuel system diagnosis errors not detected during this trip.
- No inhibition due to high charcoal canister saturation. The canister purge system cycles closed for up to 60 seconds after 240 seconds of purge under all circumstances. Once canister purge has cycled off, there is no canister load and thus no canister inhibition due to saturation.
- RPM > 512 rpm
- MAF > 49 mgstk
- Coolant Temp. > 20.25 °C
- BARO > 699.99 hPa
- Intake Air Temp > -39.75 °C
If any one of the above conditions are not met then the diagnostic function will not activate.
This diagnostic is inhibited if any of the following DTC's are present:
- Ignition coil
- Manifold air pressure sensor
- MAF or TPS ratio check
- Throttle position sensor
- Coolant temperature sensor
- Air temperature intake manifold
- Mass airflow sensor
- Camshaft sensor
- Canister purge valve electrical error
- Canister purge valve mechanical error
- Crank shaft sensor
- Crankshaft limp home mode
- Injection valve
- LOAD sensor
- O2 sensor heater
- O2 sensor deterioration, upstream
- O2 sensor deterioration, downstream
- No misfire
- Throttle valve
- Secondary air system
- Purge system, fuel system
