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