2002 Chevrolet Blazer Oxygen Sensor

It would be the sensor located after the cat converter.[/Quote:aeb38864be]
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.[/Quote:c446d90be9]

Thank you, I will check for leaks.
