P0057 O2 Sensor

So just entered Texas yesterday and got this code. It came on right after a fillup so I assumed it was a fuel cap issue. Stopped took it off and put it on, cleared the code and went on my way.

long story short it came back and I found it appears to be an O2 sensor issue, not fuel cap related.

I may have noticed that my fuel mileage dropped as well.
I am at my current location for a week before heading home.

Is it worth trying to get fixed while I’m here? Or just wait till I’m at home where I can likely do it myself.

 

The trip home is ~1300 miles.

 

Where was the fillup? Lots of rain lately, might have got some wet gas?
Or might be due for a new sensor.

 

I’ve filled up twice since. Don’t think it was gas related

 

I'd replace it if its not to much of a hassle. Emissions isn't my thing, but my understanding is out-of-whack o2 sensors can lead to the ecu fiddling with your fuel/air mix which could lead to cat fouling/damage.

 

Thats a bank 2 sensor 2 code. That would be post catalytic sensor and wouldn't affect air fuel ratios.

You can wait.

 

Thanks for the details. I appreciate it. Was nagging me for like 500 miles.

 

My dad melted a cat in his dakota. if it starts to feel way down on power, its not unheard of.
