DETAILS ON DTCS

DTC DETECTION CONDITION	A/F sensor circuit slow response
	Determination conditions	The response speed of the A/F sensor input signal when the air/fuel ratio is fluctuated is slow.
	Preconditions	Engine speed: Within specified range Charging efficiency: Within specified range Engine coolant temperature: Specified value or more Mass airflow: Within specified range The following DTCs are not detected: A/F sensor heater: P003100, P003200 ECT sensor: P011700, P011800 VSS signal: P050000 Misfire: P030000, P030100, P030200, P030300, P030400 Fuel injection correction: P017100, P017200, P209600, P209700
	Drive cycle	2
	Self test type	CMDTC self test
	Sensor used	A/F sensor
FAIL-SAFE OPERATION	Fixes duty value of A/F sensor heater Stops fuel feedback control of A/F sensor
VEHICLE STATUS WHEN DTCS ARE OUTPUT	Illuminates check engine light.
TROUBLE AREA	A/F sensor signal malfunction A/F sensor connector or terminals malfunction A/F sensor loose Exhaust system leakage A/F sensor deterioration A/F sensor heater malfunction ECM malfunction
