Where is the oxy sensor on a 2002 escort?

Answer 1

There are two. One is upstream from the catalytic converter and the other is downstream from the catalytic converter. They look like little plugs with wires going into them. The upstream one is just past the exhaust manifold. The downstream one is past the converter and can be seen from under the car. It 's in front and has a couple wires going into it.. They look like spark plugs but are different. It is hard to tell you where it is at because obviously you don't have any knowledge of the different parts of a car.
