Just to jump in and see if I can help. I am attaching the location views of where this sensor is on this engine.
We don't show a plastic cover over it but that is possible as the manuals are normally not that detailed.
Please see the info below and if you can get some pictures of what you are looking at, that will help us determine the best way to remove it if this doesn't give you what you need.
