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 greater than target idle speed for 10 seconds.
- Vehicle speed has reached one MPH at least once. Engine is in closed loop idle speed control. Highest outside temperature at last drive is 114°F (45°C) or less. Engine coolant temperature is more than 176°F (80°C). System 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). Code will set if actual idle speed is 200 RPM or more higher than target idle speed for 10 seconds.
- Engine is in closed loop idle speed control. Engine coolant temperature is more than 176°F (80°C). System voltage is more than 10 volts. Power steering switch is in off. Volumetric efficiency is 40 percent or less. Intake air temperature is more than 14°F (-10°C). Barometric pressure is more than 11 psi (76 kPa). Code will set if actual idle speed is more than 100 RPM less than target idle speed for 10 seconds.
