WHAT IS ERROR CODE P0140?

2004 GMC Envoy • 6 cylinder AWD Automatic • 65,000 miles

Enter your question. Getting error code of PO140, how is this fixed. Have had two sensors replaced that had to do with gas/air intake is this the same sensor or a different one that needs to be replaced? Service engine light soon keeps coming back on?

This is for a faulty O2 sensor, is this what was replaced?
