CKP Sensor Operation And Tonewheel - 4.7L V-8 Engine
Engine speed and crankshaft position are provided through the crankshaft position sensor. The sensor generates pulses that are the input sent to the
powertrain control module (PCM). The PCM interprets the sensor input to determine the crankshaft position. The PCM then uses this position, along
with other inputs, to determine injector sequence and ignition timing.
