DTC Set Criteria (2.4L)

Engine coolant temperature is less than 212°F (100°C) when engine is started. Intake air temperature is less than 140°F (60°C) when engine is started. Engine is in closed loop air/fuel control. Intake air temperature is more than 14°F (-10°C). Barometric pressure is more than 11 psi (76 kPa). Volume Airflow (VAF) sensor output frequency is 88 Hz or more. Code will set if long-term fuel correction continues to be more than 12.5 or short-term fuel trim continues to be more than 10.0, for 2 seconds.
