I struggled for about a week to get the sensor out and when I cleaned the well for new part instalation I could feel this metal anomaly along the wall. is this supposed to be here? cause it looks like a terrible one tap weld or a set screw was implanted here. I just bought the car and this was the part that the code reader popped up for

the point in question. located approxamatly near the enterance to the left and low slightly in the image

the crankshaft position sensor itself broke upon attempt to remove. managed to get it out via locking pliers seen in image
