Actually, I think there is only one. I would stay away from BOSCH O2 Sensors. They always seem to trip an Check Engine Light. I changed mine on my 2002 V6 once. Stayed with Motocraft, no probs.
There will be two; one in each of the exhaust manifolds.
I forgot to say that on some cars there will be another 02 sensor underneath the car, past the catalytic converter.
There are three O2 Sensors on my 1999 Cougar. Two are located just before the Y-Pipe and are both wired to the drivers side of the Y-Pipe. The other is located just after the Catalyic Converter.
Easy to change.
