Detecting the camshaft flanks
The camshaft is divided into four flanks per revolution of the camshaft (flanks 1-4). The flanks are detected by the camshaft position (CMP) sensor. The
signal affects the shape of the camshaft rotor. See also: Design See: Description and Operation/Engine Control Module (ECM)/Design
The teeth on the camshaft pulse wheel for camshaft flanks 1 and 4 are shorter than the other teeth. This enables the control module to determine the
position of the camshaft. The control module is able to establish which combustion cycle the cylinders are in.
