Details On DTCs

DESCRIPTION	A/F sensor circuit high input
DETECTION CONDITION	Determination conditions	Any one of the following conditions is met: Voltage of A/F sensor terminal F is more than specified value Voltage of A/F sensor terminal D is more than specified value Voltage of A/F sensor terminal B is more than specified value
	Preconditions	Switch the ignition ON (engine off or on) Battery voltage: 11-18 V ^1 The following DTC is not detected: Internal PCM malfunction: P064D:00 ^1 : Value can be verified by displaying PIDs using M-MDS
	Drive cycle	2
	Self test type	CMDTC self test, KOER 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 connector or terminals malfunction PCM connector or terminals malfunction Short to power supply in wiring harness between the following terminals: A/F sensor terminal F-PCM terminal 1W A/F sensor terminal D-PCM terminal 1AB A/F sensor terminal B-PCM terminal 1AG A/F sensor malfunction PCM malfunction
