I have a few questions about crank sensors. I removed mine because the car shut off while driving and had no spark or injectors firing. I bought a replacement the one to the right in the attached photo. The one to the left is the original I pulled off. First question, is the one to the left an original piece or is it a replacement? The old one was enclosed in a cage which would slide in the mounting bracket attached to the timing chain cover. Second question the new one does not fit exactly in the cage. I think I can modify the cage enough to make it work, has anyone else done this. The second photo shows the top view of the different width. I was told by one person that there was 3 generations of crank sensors each one getting progressively smaller. The next person told me the newer version is larger so which story is true.
