Crankshaft Position Sensor: Description and Operation
Crankshaft Position (CKP) Sensor 7X
DESCRIPTION
The 7x crankshaft position sensor is the other Hall-effect switch closer to the crankshaft. The interrupter ring is a special wheel cast on the crankshaft
that has seven machined slots, six of which are equally spaced 60 degrees apart. The seventh slot is spaced 10 degrees from one of the other slots. as the
interrupter ring rotates with the crankshaft, the slots change the magnetic field. this will cause the 7x the Hall-effect switch to ground the 3X signal
voltage that is supplied by the ignition control module. The ignition control module interprets the 7x "ON-OFF" signals as an indication of crankshaft
position. The ignition control module must have the 7x signal to "fire" the correct ignition coil.
The 7x crankshaft position sensor uses a two wire connector at the sensor and a three-way connector at the ignition control module.
