When I start up my car there is a slight gas odor. When I pull up the codes I get "Heated oxygen sensor", I don't have the codes on hand right now so I can't really be specific. I don't belive it to be the FPR because I had that replaced maybe a year ago. Any help would be great

The code will tell you which sensor is reporting the problem. They are numbered as follows:
Bank 1, Sensor 1: In the exhaust manifold for the rear cylinder bank
Bank 1, Sensor 2: Just before (in front of) the catalytic converter
Bank 1, Sensor 3: Just after (behind) the catalytic converter
Bank 2, Sensor 1: In the exhaust manifold for the front cylinder bank
Whichever it is, replace that sensor and the problem will be solved. If you need more details, we will need to know what year and model car you have.
