Troubleshooting code P1167 for my 2002 Hyundai Santa Fe

We have a safety inspection coming up and our check engine light came on (of course). We went to autozone and it said that our o2 sensor needed to be changed or whatever so we got the new o2 sensor and after we fixed it the light went off for a couple of days. Well low and behold the light came back on and when we took it back in it says code p1167. I am sick of paying the ridiculous amount they charge at the dealership to get little things fixed! Does anyone have an idea for what that code means?

    could be a bad sensor right out of the box. A vaccume leak or MASS AIR FLOW sensor .Air filter not installed properly , air tube loose between air filter box and engine.
