29 Camshaft Position Sensor and Engine Speed Sensor Circuit A.1 Camshaft Position Sensor (left) B.2 Camshaft Position Sensor (right) C. Crankshaft Position Sensor Camshaft Position Sensor (G1 and G2 signals) and The engine speed sensor (NE signal) consists of a signal board and an induction coil (Figure 29). The G1 and G2 signal boards are mounted on the left and right camshafts, respectively, with one tooth on the outer circumference of each plate. As the camshaft rotates, the air gap on the protuberances on the signal board and the induction coil changes, causing the magnetic field to fluctuate and produce electric motion in the induction coil
