This is what it the part looks like.

Yes I think I can see the wire going to that direction but how do I have access to have it removed and replaced?

So with the car raised in the air and the under covers removed, the sensor will be hidden in a very small crevice to the left of the catalytic converter’s heat shield.
You’ll have to remove two heat shields (to the left of the catalytic heat-shield I mentioned before) to be able to find it.
The sensor itself is held in by 2 E-Torx screws, and is in a horrible position to reach.
What helped me was to remove the air box and both heat shields from under the hood before you raise the car up.
Personally my hands are way too large to feel around inside that crevice for the sensor clip and bolts, so I would recommend using a mirror to find where everything’s located at.
Technically you should only need a thin 1/4” flex ratchet with a stubby extension and a swivel E-Torx socket (do not quote me but I believe it was an E8 male torx socket).
Sorry I don’t have any pictures to show you, but hope this helps.

Thank you Kevin,
My C300 the air box is on the right side and I removed but my arm does not reach the sensor. Apparently mine is in the back under the ECU. Thank you once again.
