Removing and Installing Camshaft Position Sensor
The intermediate shaft and the distributer have both been eliminated on the AEG engine. This required the CMP Sensor to be moved to a new position. It is now mounted behind the camshaft drive belt sprocket, with the trigger wheel attached to the back of the sprocket.
The four trigger wheel windows (two wide and two narrow windows) pass the sensor in a distinctive sequence that in turn produces a distinctive pulse width pattern for each 90 degrees of camshaft rotation.
The ECM identifies camshaft position and determines the fuel injection and ignition sequence before the engine has completed a half revolution. This results in improved engine starting and reduced cold-start emissions.
