How many O2 sensors does this car have?

Hello,

There are four oxygen sensors on this vehicle. Two in the front and two in the rear of the engine. I attached some diagrams below showing the connector locations on the engine, the sensor will plug in there where it is highlighted and screw into the exhaust pipe either on the catalytic converter or the pipe itself. The two front sensors are fairly simple to replace whereas the rear sensors will be more involved.
