• Before the ECM performs the idle test, the vehicle must be driven under the following conditions:
  • The engine speed is greater than 915 RPM
  • The engine run time is greater than a calibrated value
  • Both conditions exist for greater than 15 s
• The throttle is in the rest position.
• The intake air temperature (IAT) is between -20 to +250°C (-4 to +482°F).
• The ignition voltage is greater than 11 V.
• The engine coolant temperature (ECT) is between 40-127°C (104-261°F).
• The barometric pressure (BARO) is greater than 70 kPa.
• The engine has been idling less than 50 s.
• The vehicle speed is less than 2 km/h (1 mph).
• The short term fuel trim is learned.
• The air flow into the engine is between 3-13 g/s.
• The EVAP purge concentration is learned.
• The catalytic converter (TWC) calculated temperature is between 450-250°C (842-1,742°F).
• The engine is operating in Closed Loop.
• The transmission is not in P/N (automatic transmission only).

This diagnostic attempts one test during each valid idle period once the above conditions have been met. This diagnostic attempts up to 8 tests during each drive cycle.
