DTC Set Conditions

These check conditions apply when engine coolant temperature is less than approximately 212°F (100°C) when the engine is started. Intake air temperature is less than 140°F (60°C) when engine is started. Under the closed-loop air/fuel ratio control. Engine coolant temperature is more than 171°F (77°C). Volume airflow sensor output frequency is 88 Hz or more. Judgment criteria is when long-term fuel trim has continued to be more than 12.5 percent for 5 seconds or short-term fuel trim has continued to be more than 10.0 percent for 5 seconds.
