Before the ECM performs the idle test, the vehicle must be driven under the following conditions:
- The engine speed is greater than 1,000 RPM
- The engine run time is greater than 120 seconds
- Both conditions exist for greater than 16 seconds
The vehicle speed is less than 2 km/h (1 mph)
The throttle position (TP) is less than 2 percent
The mass air flow (MAF) is greater than 12 g/s for greater than 30 seconds
The engine is operating in Closed Loop
The fuel trim learn is enabled
The Engine Coolant Temperature (ECT) is between 40-130°C (104-266°F)
The Barometric Pressure (BARO) is greater than 70 kPa
The Catalytic Converter Calculated Temperature parameter is between 400-640°C (752-1,184°F)
The Intake Air Temperature (IAT) is greater than -20°C (-4°F)
The battery voltage is greater than 11 volts
The transmission is in gear-Automatic transmissions only
The short term fuel trim (FT) is between -10 and +10 percent
This diagnostic attempts one test during each valid idle period once the above conditions have been met. This diagnostic attempts up to 6 tests during each drive cycle.
