Item		Detecting Condition	Possible Cause
DTC Strategy		Heater performance check	Poor connector connection Faulty HO2S (Bank1, Sensor1) heater
Enable Conditions	Case 1	Normal auxiliary battery voltage (10 to 16V) Time after sensor heating is less than 35s Internal resistance signal is valid
	Case 2	Normal auxiliary battery voltage (10 to 16V) EGT around FO2S (model) is more than 450°C (842°F) Power of sensor heating is more than 90% Sensor heating time is more than 50s Fuel system status is no fuel cut-off over 50s Internal resistance signal is valid
	Case 3	Normal auxiliary battery voltage (10 to 16V) EGT around FO2S (model) is more than 450°C (842°F) Sensor heating time is more than 50s Fuel system status is no fuel cut-off over 50s Internal resistance signal is valid
Threshold Value	Case 1 (Start phase diagnosis)	Ceramic temperature is less than 720°C (1, 328°F) for 35s after heating start
	Case 2 (Permanent diagnosis)	Ceramic temperature is less than 720°C (1, 328°F)
	Case 3 (Low temperature diagnosis)	Ceramic temperature is less than 639°C (1, 182°F)
Diagnostic Time	Case 1	3s
	Case 2	60s
	Case 3	10s
MIL ON Condition		2 driving cycles
