OXYGEN SENSOR

2002 Chevrolet Blazer

Can anyone tell me where Bank 1 Sensor 2 Oxygen Sensor is located? I can find 3 sensors, 1 on the drivers side of the engine, 1 on the passenger side and 1 after the cat.

It would be the sensor located after the cat converter.

Thank you, I have replaced that sensor and still get the same Error message P0141. I thought that the new 02 sensor might be bad so I replaced it with another one with the same problem. Any suggestions?

If you are using aftermarket sensors, I highly suggest using AC Delco sensor.I have run into many problems with aftermarket O2 sensors, especially " universal" sensors some of the parts stores sell. Hope this helps.
