I had a diganos done on it and test came out saying that both of the sensor is not working. The guy at Advance Auto say that is very rare that both of aren't working. Any one know what it maybe or any suggestions before I replace them?

I am assuming that you have a V6 being there are two O2 sensors on your vehicle. It only takes one O2 sensor to trip the code. There is a way to test the 02 to get a reading on see if it is good or not. The mechanic is most likely replacing them both for PM ( Preventive Maintenence). Why replace one and maybe have you come back in a week or a month with the same problem when the other one goes bad next ?Kinda like if you have a bad spark plug . Wouldnt it make more sense to replace all of the plugs ? Or just the bad one? Hope this helps

A O2sensor will go bad and yes it is rare to have both go out, but not unheard of.Is the car running rich< are you using a lot of gas. This is a sure sign that the O2 has gone nuts.
