WARNING: This page is about a different variant/trim than selected.

DTC	CONSULT screen terms (Trouble diagnosis content)	DTC detection condition
P0030	A/F SEN1 HTR (B1) [A/F sensor 1 heater (bank 1) performance]	Diagnosis condition	Start engine and let it idle
		Signal (terminal)	A/F sensor 1 heater signal
		Threshold	Voltage signal transmitted from A/F sensor 1 heater to ECM is higher/lower than voltage in the normal range
		Diagnosis delay time	--
P0031	A/F SEN1 HTR (B1) [A/F sensor 1 heater (bank 1) control circuit low]	Diagnosis condition	Start engine and let it idle
		Signal (terminal)	A/F sensor 1 heater signal
		Threshold	An excessively low voltage signal is sent to ECM through the A/F sensor 1 heater
		Diagnosis delay time	--
P0032	A/F SEN1 HTR (B1) [A/F sensor 1 heater (bank 1) control circuit high]	Diagnosis condition	Start engine and let it idle
