RAM 1500 Van V8-5.2L CNG VIN T (1999)
Sensor Operation
On these engines, the flywheel/drive plate has 8 single notches, spaced every 45 degrees, at its outer edge.
The notches cause a pulse to be generated when they pass under the sensor. The pulses are the input to the PCM. For each engine revolution, there
are 8 pulses generated on V-8 engines.
The engine will not operate if the PCM does not receive a crankshaft position sensor input.
