02 Sensor Code
 

Pulled up a P0155 code today. 02 sensor heater circuit. I'm finding its most likely the drivers side upstream sensor. My question is can I drive and be ok until Monday? Being Saturday evening everywhere already closed

The short answer is yes you should be fine. You may notice fewer mpg's. I would swap the O2 from one side to the other and see if the code follows the O2
