I have a '97 2.2 Accord. The code reader provided the following code: PO141 O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2). Any suggestion as to how to fix this? Where is this sensor located?

Thanks,

Mark

 

It is the second O2 sensor, in the converter. Heater failure codes are pretty clear cut. Check voltage between the two black wires, there w3on,t be any. If you are under 150,000 miles you will still be under Hondas emission extension warranty and it will be free.
