I had the O2 sensor replaced on the above car. However the "Check Engine" light stayed on. I was told that there are 4 O2 sensors or the car and that another one must also be bad. I took the car back to have the problem fixed. The "Check Engine" light came back on after only a few minutes of driving. Are there 4 O2 sensors? If so would they all go bad at the same time? How much should it cost to have one replaced?

Read your codes before replacing parts...OBDI 02 sensors were good for about 50,000.
