Details On DTCs

DETECTION CONDITION AND POSSIBLE CAUSE

DESCRIPTION	A/F sensor circuit slow response
DETECTION CONDITION	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: P0031:00, P0032:00 ECT sensor No. 1: P0117:00, P0118:00 VSS signal: P0500:00 Misfire: P0300:00, P0301:00, P0302:00, P0303:00, P0304:00 Fuel injection correction: P0171:00, P0172:00, P2096:00, P2097:00
	Drive cycle	2
	Self test type	CMDTC self test
	Sensor used	A/F sensor
FAIL-SAFE FUNCTION	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.
POSSIBLE CAUSE	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 PCM malfunction
