Now to only wait until it'* warm to replace it. Might as well do the timing chain and tensioner. :(
That'* a pretty safe assumption, but one that can be easily proven without too much work.
1.) Take the sensor back out, disconnect the ignition at the module, then remove the spark plugs (just to make it easier to turn over by hand.)
2.) Rotate the motor by hand while watching the cam sprocket. It may take as much as two complete revolutions to bring the cam sprocket around to where the magnet should be. (Note, the hole with the magnet will be different than the other lightening holes..it is closer to the chain and will line up better with the hole in the timing cover.)
If you don't see the black disk of the magnet, then it'* down in the pan someplace, stuck to one of the main caps, or got destroyed by the moving parts under the timing cover.
At this point, look up one of the old threads on how to put the magnet back in without taking off the timing cover.
