Test fuses first!!... The sensor in question is the one BEHIND the catalytic converter (downstream) 02 sensor.... Check wires, wire connector and terminals for damage/corrosion etc.... It is possible the heater in the sensor has failed which requires replacement of that sensor.... Strongly suggest buying OEM sensor or it's equivalent.!!!!.... IF it is found to be your problem....
