If you have a crank angle sensor fault on these engines, often if it is not a faulty sensor they have a known fault with the crank shaft thrust bearing, what they can do is the thrust chops out and actually drops into the sump. If this happens the crank shaft has excessive end float that the crank shifts across in the block a few MM just enough to cause the crank shaft segment to not read on the sensor, if you can push the crank back and forward a few MM this will be the problem. This is more of a problem with manual transmissions as each time you push the clutch the force of the clutch being depressed applies pressure on the thrust and over time this problem can develop. I have seen some 20 or more do this over the years.
So check the crank shaft end float first, you should have no movement there that you can feel or see.
