If the crankshaft position sensor output is delayed for an instant then the ECM cannot possibly coordinate that properly with the camshaft position sensor. If the sensor is working intermittently as in the case of the faulty 2002-2006 sensors then the ECM doesn't know where the gap on the teeth is. When the teeth on the signal plate of the crankshaft rotate this causes the magnetic field to be blocked and unblocked which causes the secondary voltage to oscillate.The voltage supplied by the sensor then amplifies this voltage if positive or does nothing if zero and sends it to the ECM. The teeth of the signal plate at the end of the crankshaft cause a gap as they rotate which is read by the crankshaft position sensor as a change in secondary voltage created on the magnetic field at a 90 degree angle to the magnetic field on the integrated silicon circuit. You don't understand what a Hall sensor does when reading the crankshaft position? The sensor consists of a magnet and an Integrated Circuit. You are incorrect about the 2007 crankshaft position sensor reprogramming of the ECM on the 2002-2006 Altima.
