DTC Set Criteria
- Vehicle speed has reached one MPH at least once. Engine is in closed loop idle speed control. Code will set if actual idle speed is 300 RPM or more higher than target idle speed for 12 seconds.
- Vehicle speed has reached one MPH at least once. Engine is in closed loop idle speed control. Maximum atmospheric air temperature is less than 113°F (45°C) during closed loop idle speed control. Engine coolant temperature is more than 180°F (82°C). Battery voltage is more than 10 volts. Intake air temperature is more than 14°F (-10°C). Barometric pressure is more than 11 psi (76 kPa). Intake air temperature is more than 14°F (-10°C). Code will set if actual idle speed is 200 RPM or more higher than target idle speed for 12 seconds.
- Engine is in closed loop idle speed control. Engine coolant temperature is more than 180°F (82°C). Battery voltage is more than 10 volts. Power steering pressure switch is off. Volumetric efficiency is less than 40 percent. Barometric pressure is more than 11 psi (76 kPa). Intake air temperature is more than 14°F (-10°C). Code will set if actual idle speed is more than 100 RPM less than target idle speed for 12 seconds.
