DTC P0133 Ho2S Circuit Slow Response (Bank 1/Sensor 1): DTC Detecting Condition

DTC DETECTING CONDITION

Item	Detecting Condition	Possible Cause
DTC Strategy	Comparison of O2 sensor lean/rich period with calculated period	Leak in intake or exhaust system Faulty fuel system. Front and rear HO2S connections reversed. Contact resistance in connectors HO2S contamination
Enable Conditions	400°C (752°F) < Catalyst Temp.Model < 900°C(1652°F) Coolant temp. > 70°C (158°F) 1200 < Engine speed (RPM) < 3000 300 < Mass air flow (mg/rev.) < 840 No misfire detected Not transient condition
Threshold Value	Sum of O2 sensor lean/rich period > calculated period
Diagnostic Time	70 lambda controller cycles
MIL On Condition	2 Driving Cycles
