How many o2 sensors
My car has an automatic transmission.

A: Your vehicle will have two oxygen sensors. ...

Your vehicle will have two oxygen sensors. Both of them are located on the exhaust manifold. One of them will be located before the catalytic converter, and is typically located rather close to the engine. This is the hardest one to get to one your vehicle. The second is located after the catalytic converter. They use two sensors to identify if there is an issue with the catalytic converter (and other engine inputs). The second should be visible from under the vehicle without any major issues. The first is the tricky one. You may need to remove some components to gain access to the area.
