First if all, unless you take your car to the dealer for tune-ups etc, the
crankshaft sensor in the front of the engine is of no use. It is only used
by some OLD equipment used in some dealerships. It has no effect on the way
the car runs. As you say, the sensor goes at the front of the engine behind
the fan and the other end should go to the diagnostic connector on the left
inner finder (the one with the cap on it.). Mine doesn't have a 3 pronged
plug so I am not sure how yours is hooked up. There is a 3 pronged plug for
the throttle switch. It is located on the left inner finder also. Maybe
there is something hooked up incorrectly up there.
