2006 SIlverado 5.3

I have codes P0050 (O2 heater control circuit - bank 2 sensor 1), P0059 (O2 heater resistance - bank 2 sensor 1), and P0154 (O2 sensor circuit no activity detected - bank 2 sensor 1). Could this just be a bad O2 sensor? I'm due for a smog at the end of this month and I've been tryin to figure this mess out for a couple weeks. Any help is greatly appreciated!!

That's what it sounds like. Check the wiring first. Make sure the connection is clean. I would clear the codes and then see if they come back before replacing the sensor.

 

If you google "O2 sensor test", you will find some good info. Here is one link that provides a description of how the sensor works and how to test it:

Only one of those sounds like a possible obd2 code.

 

I notice you are in California....the Emission inspection is very strict. I do not think you can just clear the code, I think you need to show that something was fixed or replaced.

At 6 years old, I would think more than one may be sluggish.

I would go with the ACDelco 213-3533

 

Thanks for the replies, it ended up being a crappy connection. Used some contact cleaner, plugged it in, cleared the codes and it's been good. No engine light. Runs strong. Now I can get er smogged and put on the market....
