Crankshaft Position Sensor: Description and Operation
24X and 7X CKP Sensors/Harmonic Balancer Interrupter Ring
24X Crankshaft Position (CKP) Sensor
7X Crank Shaft Position (CKP) Sensor
The 24X crankshaft position sensor (1), secured in a mounting bracket (3) and bolted to the front side of the engine timing chain cover (2), is partially
behind the crankshaft balancer.
The 7X crankshaft position sensor uses a two wire connector at the sensor and a three-way connector at the ignition control module.
The 24X crankshaft position sensor contains a Hall- effect switch. The magnet and Hall-effect switch are separated by an air gap. A Hall-effect switch
reacts like a solid state switch, grounding a low current signal voltage when a magnetic field is present. When the magnetic field is shielded from the
switch by a piece of steel placed in the air gap between the magnet and the switch, the signal voltage is not grounded. If the piece of steel (called an
