The 02 Sensor located at the passenger side about the rear door is at the top of the exhaust pipe next to the floor with about 1 1/2" clearance. Does the exhaust pipe have to be removed to replace this 02 sensor.?The second one is located on the Drivers side below the exhaust manifold and is accessible.

You do not have to remove the exhaust pipe to get this out, but it is not easy when doing it on the ground. You really need to access it from underneath so jack the vehicle as high as possible and then you will most likely have to use an open end wrench to get to it.

Here are the instructions from the manual.

Let us know if you still can't get it and we will see about getting more detail. Thanks
