- >>Figure 1 is a depiction of typical scope patterns of the cam (1) and crank (2) sensors for 4, 6, and 8 cylinder engines. The square wave patterns are uniform and are identical to one another. The patterns must be evenly spread apart and at the same height. The larger gap pattern (signature) after the shorter wave forms are used for cylinder identification (crank signal) and the distance between the series of slots (trigger) on the camshaft pulley (cam signal). Any variation of the pattern will indicate an issue with the sensor, wiring, or trigger (target) wheel.<<
