I had another post but no one responded, so I did a little research, and came across something called a vapor box, around the same area as my problem. My car has this hissing sound comming from the rear drivers side wheel, as if it was leaking air form the tire, but its not. I only hear it when the car is on, and now that I think of it, once and a while I do smell gas around my car. Is there a problem with my vapor box? What does ti do? What problems does it cause? Help! Thanks

Today while driving, I got the CEL. I pulled the code 07 07, which is the Rear Heated O2 Sensor. I had it for the first time a couple of months ago, but resetted the ECU and it hadn't come back till now. Could this sensor have anything relationship with he vapor box and the noise im having? anyone???????
