• 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 10 minutes
  • Both conditions exist for greater than 1 minute
• The throttle is in the rest position.
• The intake air temperature (IAT) is between -20 to +85°C (-4 to +185°F).
• The ignition voltage is greater than 11 volts.
• The engine coolant temperature (ECT) is between 70-125°C (156-257°F).
• The barometric pressure (BARO) is greater than 70 kPa.
• The vehicle speed is less than 3 km/h (2 mph).
• The short term fuel trim is learned.
• The short term fuel trim (FT) is between -10 and +10 percent.
• 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 6 tests during each drive cycle.
