CRANKSHAFT POSITION SENSOR
(CKPS)
E1852BDD
Piston position on combustion chamber is the substantial
to define the starting of injection timing. All engine pistons
are connected to crankshaft by connecting rod. Sensor
on crankshaft can supply the informations concerning all
piston positions, revolution speed is defined by revolution
per minute of crankshaft. Prior input variable is determined
at ECM by using signal induced from crankshaft position
sensor.
