- Before the ECM performs the idle test, the vehicle must be driven under the following conditions:
- The calculated air flow into the engine is more than 9 g/s for more than 16 seconds for a manual transmission.
- The calculated air flow into the engine is more than 11 g/s for more than 13 seconds for an automatic transmission.
- The engine has been running for more than 9.5 minutes.
- The throttle angle is less than 1.5%.
- The EVAP purge concentration is learned.
- The long term fuel trim is learned.
- The air flow into the engine is between 2-8 g/s.
- The engine has been idling less than 60 seconds.
- The vehicle speed is less than 3 km/h (2 mph).
- The engine coolant temperature (ECT) is between 70°-109°C (160°-228°F).
- The intake air temperature (IAT) is between -7°C and +105°C (+19° and +221°F).
- The barometric pressure (BARO) is more than 72 kPa.
- The catalytic converter (TWC) calculated temperature is between 300°-920°C (662°-1,688°F).
- The vehicle is running in Closed Loop.
- Torque fuel reduction is not active.
- The transmission is not in P/N (automatic transmission only).
- The engine speed is steady within 80 RPM.
- The A/C clutch is not changing state.
- The cooling fan is not changing state.
This diagnostic attempts one test during each valid idle period once the above conditions have been met. This diagnostic attempts up to 12 tests during each drive cycle.
