Operation
OPERATIONThe
crankshaft position sensor and
camshaft position sensor are hall effect devices. The camshaft position sensor and crankshaft position sensor generate square wave pulses that are inputs to the Powertrain Control Module (PCM). The PCM determines engine position from these sensors. The PCM calculates injector sequence and
ignition timing from crankshaft AND camshaft position.
