It has two.
== == 1996 Corolla's have two oxygen sensors. The first sensor, is pre catalytic converter. It is located on the exhaust manifold. The second sensor is post catalytic converter.
Two, one before the cat, one after.
How many O2 sensors does a 2002 Saturn L300 V6 3 l have all together?
there are two oxygen sensors mounted in either the manifolds or close to the engine in the y pipe . 1996 and newer have 4 or downstream sensors after the catalyic converter
2 ... one on top and one underneath the exhaust header
