Pic. 2.228. Camshaft position sensor output waveform: 1 - camshaft position sensor; 2 - intake camshaft; 3 – angle of rotation of the camshaft 30°; 4 - angle of rotation of the crankshaft; 5 - output signal of the camshaft position sensor; 6 - engines LF and L8; 7 - engine L3
To identify the cylinder, the camshaft position sensor detects the camshaft angle 30 degrees after the top dead center of the piston of the first cylinder. The waveform of the output signal of the camshaft position sensor is shown in Figure 2.228.
