sets of double notches and three sets of single The notches cause a pulse to be generated when they pass under the sensor. The pulses are the input The engine will not operate if the PCM does not receive a CKP sensor input. OPERATION - 5.2L/5.9L Engine speed and crankshaft position are provided through the CKP sensor. The sensor generates pulses The sensor is a hall effect device combined with an internal magnet. It is also sensitive to steel within a On 5.2/5.9L V-8 engines, the flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its The notches cause a pulse to be generated when they pass under the sensor.
