I had engine lite analyzed indicating 02 sensor problem. How many sensors are there and where are they located? How are they replaced? I have experience as mechanic but never have I changed these. Your help is appreciated.

Hi fishman34,

Some models have one and some have two.

One piece is located on the exhaust under the intake manifold.

The other piece would be after the catalytic converter.
