HelloCustomer The bank one sensor one oxygen sensor is located in the exhaust manifold at the very front of the engine compartment. It is very straight-forward to replace, you need a 7/8" open end wrench or an oxygen sensor tool (as shown) to remove it. It simply unscrews from the manifold. In some rare cases it will be seized in the manifold and you will need to heat around the sensor with a torch to remove it.

Sure here is a pix of where it should be. Also, you may need to remove the shield which covers the manifold to access the sensor.graphic
