i replaced the crank sensor in my car today. The car started and ran for about 10 minutes and then suddenly died. Pulled the crank sensor back out and saw where the ring had been rubbing up against it. In the picture that I posted you can see the wear on the crank sensor after 10 minutes of running. Is this enough damage to make the car stop running? It appears that the ring or fin is running through the gap in the crank sensor at a slight angle, making it touch on the left hand side of the gap.
