DTC P0160 Ho2S Circuit No: Activity Detected (Bank 2/Sensor 2): DTC Detecting Condition

DTC DETECTING CONDITION

Item		Detecting Condition	Possible Cause
(Case1)	DTC Strategy	Circuit malfunction	Open in signal harness Open in ground harness Contact resistance in connectors Faulty Heated O2 Sensor (HO2S)
	Enable Conditions	Sensor preheating and full heating phases finished Battery voltage > 10V Lambda control active
	Threshold Value	0.37V < Sensor voltage < 0.54V (during 10 sec.)
	Diagnostic Time	1 Sec.
(Case2)	DTC Strategy	Check time to closed loop control start with O2 sensor voltage
	Enable Conditions	Battery voltage > 10V
	Threshold Value	Time to closed loop control not activated when O2 sensor voltage blocked between 0.37~0.54 V > 90~ 200 sec (depends on coolant temp, at start)
	Diagnostic Time	Immediate
MIL On Condition		2 Driving Cycles
