They are usually round. Your vehicle will have 4 of them. Two upstream (before the catalytic converter) on each side exhaust and 2 downstream (after the catalytic converter) on each side exhaust. If you have a code from a check engine light, the code definition will better explain what is wrong with which of the 4 O2 sensors.

That is the passenger side of the engine. Is it downstream or upstream?
