Camshaft Position Sensor: Description and Operation
Hall Generator
PURPOSE
The Engine Control Module (ECM) uses the input from this sensor to determine ignition and fuel injection timing.
Standard Wave Pattern
OPERATION
The trigger wheel mounted on the distributor shaft rotates within a space in the hall sensor.
-
As the distributor shaft rotates the trigger wheel shutter passes through the opening, temporarily blocking the magnetic field, causing the
voltage signal to drop.
-
As the shutter passes the hall sensor and no longer blocks the magnetic field the voltage rises.
-
Power to the camshaft position sensor is supplied from the MFI relay and the ground is located in the body.
