Summit Wagon AWD L4-1795cc 1.8L SOHC (1994)
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.
-
A 5V voltage is applied from the engine control module to the camshaft position sensor output terminal and the camshaft position sensor
generates a pulse signal as it switches from OPEN to SHORT (power transistor inside the sensor switches ON/OFF) between the output
terminal and the ground.
CONSTRUCTION
Both sensors are incorporated into one unit consisting of a semiconductor wafer element and a permanent magnet.
-
A rotating shutter called the trigger wheel acts as a switching device to produce the Hall signal.
