Cylinder Identification Sensor

Located on right front of engine, near distributor, sensor uses an inductive pick-up looped around No. 6 spark plug wire to give fuel injector group identification information to MCU. This allows MCU to activate each injector group (1-3-5 and 2-4-6) once every working cycle (360 degrees).
