300E a couple 1994 w124wagon E320 Wagon/,1971MGB Track/Rally, MG Midget Autocross ,2000 E320 wagon.
Out sighting in a new scope on my

8mm Mauser.
so I can't take a picture but it is the sensor about 7 inches or so to the right of the camshaft position sensor that you can see sticking out of the passenger side cylinder head(also known as bank one)
You can probe test it with a multimeter resistance decrease exponentially with engine coolant temp increase.
Also make sure it is plugged in at the harness and that the connection is clean and clear of oil.
Lastly you might want to erase the code and see if it comes back.At times sensors like to throw a false code just to get your dander up
