Spirit L4-153 2.5L SOHC VIN K TBI (1993)
Ignition Hall Effect Sensor: Description and Operation
Hall Effect Distributor
Hall Effect Pickup Assembly
LOCATION
Sensor (pick-up), mounted on distributor plate.
PURPOSE
Powertrain Control Module (PCM) uses sensor input to determine engine speed and cylinder identification, and synchronizes fuel injection
accordingly.
OPERATION
Pick-up generates pulses when shutter blades interrupt magnetic field in pick-up.
THEORY
Hall effect switch is mounted opposite a magnet.
A shutter wheel, containing four shutters, (one for each cylinder), passes between Hall effect switch and magnet.
When a shutter interrupts magnetic field, the switch turns OFF. When the shutter passes, the magnetic field is sensed, and the switch is turned ON.
