• 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 condition exists for greater than 1 minute
• The engine run time is greater than 10 minutes.
• The engine is operating in Closed Loop.
• The engine coolant temperature (ECT) is between 70-125°C (156-257°F).
• The barometric pressure (BARO) is greater than 70 kPa.
• The catalytic converter (TWC) calculated temperature is between 450-250°C (842-1,742°F).
• The intake air temperature (IAT) is between -20 to +85°C (-4 to +185°F).
• The ignition voltage is greater than 11 volts.
• The vehicle speed is less than 2 km/h (1 mph).
• The throttle position is in the rest position.
• The engine has been idling less than 50 seconds.
• The short term fuel trim (FT) is between -10 and +10 percent.
• 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 6 tests during each drive cycle.
