Camshaft Position Sensor Details For Cadillac?

In this section he details are provided for Camshaft Position Sensor DESCRIPTION & OPERATION.

The camshaft position (CMP) sensor is also a magneto resistive sensor, with the same type of circuits as the crankshaft position (CKP) sensor. The CMP sensor signal is a digital ON/OFF pulse, output once per revolution of the camshaft. The CMP sensor information is used by the PCM to determine the position of the valve train relative to the crankshaft position.

The camshaft reluctor wheel is part of the camshaft sprocket. The reluctor wheel profile is a smooth track, half of which is of a lower profile than the other half. This allows the CMP sensor to supply a signal as soon as the key is turned ON, since the CMP sensor reads the track profile, instead of a notch.

These details will help.
