There was a discussion about the two crank shaft sensors recently. I think it it was oab-au who said what each sensor was sending to the ECU. Basically the ECU needs to know the position of the crankshaft twice for each revolution. I don't remember exactly why though, but each crank sensor triggered some sort of response from the ECU.



Interesting fact: the SVX actually has one crank shaft sensor and two cam shaft sensors. It uses one of the cam shaft sensors as a crank shaft sensor. Weird!
