Is there any difference between the front & rear O2 sensors?

The cable is a different length for the sensors, and they have a different part number.

Other than that, no - you can often test a problem to see if the front O2 sensor is bad by swapping the rear one into its place.

Front sensor part number is 15097
Rear sensor part number is 15062

You must buy Bosch when replacing these, or you car will complain to you. Those are Bosch part numbers.

Other than that...


They are also different visually...

Front one have vertical line openings on it and the rear one have openings which looks like dots.
