P2270 Code

This code popped up on my 03 XLT about a month ago, I erased it and it came back a month later. I dont know the history of this vehicle but where should I go first, I was thinking the fuel filter. O2 sensor stuck lean-Bank 1, Sensor 2. Doesnt run any different than it usually does. Anyone with any other ideas? I have the 4.0 v6 168,000 miles

That one may indeed be a bad 02 sensor.

Bank 1 sensor 2 would be the after cat 02 sensor on the passenger side

Thanks JT but if it was the o2 sensor, wouldnt the light come right back on instead of a month later? and what is the cost of one, I have no idea.

I think they are around 75.00 give or take.
