In theory. However monitoring by #'s does not give you a clear picture of what the sensor is doing. In a graph form you can see in greater detail the fluctuation of the rear sensors. If the computer is showing a p0420 code, there is almost definately a problem with the convertor.
This vehicle has B1 and B2 convertors side by side directly off the manifold. They can not be separated.
