DTC P0130 Ho2S Circuit (Bank 1/Sensor 1): DTC Detecting Condition

DTC DETECTING CONDITION AND POSSIBLE CAUSES

Item		Detecting Condition	Possible Cause
DTC Strategy		Rationality check	Poor connection Open or short power/ground in signal circuit B1S1 ECM/PCM
General Enable Conditions		Dew point end detected Required lambda = 1 Battery voltage > 10.7V Exhaust gas temperature (model) < 800°C (1472°F) Heater control enabled
Case1	Enable Conditions	B1S2 sensor voltage > 0.5V
	Threshold Value	B1S1 sensor voltage: 0.06-0.4V
	Diagnostic Time	25 sec
Case2	Enable Conditions	B1S2 sensor voltage < 0.1V
	Threshold Value	B1S1 sensor voltage: 0.6-1.08V
	Diagnostic Time	10 sec
Case3	Enable Conditions	Time after dew point end detected > 10s
Case3	Threshold Value	Counter of \| Δ usvk > 2V during 0.04 sec. after heater on-->off \| > 5 times
MIL ON Condition		2 driving cycle
* Δ usvk: Sum of the signal voltage change value (B1S1) * B1S1: upstream oxygen sensor/B1S2: downstream oxygen sensor
