Default Check Engine Light on - Fixed and Light back on

Check engine light came on. Put on machine to give me code.
Code was P0136 (O2 Sensor Circuit malfunction) Mechanic Replaced the O2 sensor with a brand new one and couple days later, Check Engine light came back on. Not sure what to do now. Live with having Check Engine light on?

What are you working on?

Something is causing the light to come on.

Any other codes?

Pretty sure the Grand Prix has four. I know my Blazer does. OP, you might also check the wires for any obvious signs of damage maybe?
