The PMH sensor (or high deadline sensor) is a magnetic sensor or with a hall effect installed on the engine block, generally facing the engine steering wheel or the crankshaft pulley. It detects the passage of one or more missing teeth on a notched crown (called target or soundtrack) attached to the crankshaft. It makes it possible to precisely determine the angular position of the crankshaft, and more precisely the moment when the piston n ° 1 reaches the high point (PMH), that is to say its highest position in the cylinder.
