Determining Hall Effect sensor pinouts
Using a multimeter with a diode drop function (triangle with a line next to it), you can work out the pinout of an unknown Hall Effect sensor. This is a super simple schematic of what we're looking for (voltage can only go in the direction of the arrow):
Put the positive probe onto a wire, and check for a circuit to each other wire. When you find the wire that gives a circuit to both other wires, you're on the sensors' power wire.
Put the positive probe onto one of the remaining two wires. If you get a circuit to the other wire, you're on the sensors' ground pin.
The remaining wire is therefore the sensors' signal wire.
Hall Effect or Reluctor?
The two most important sensors on your engine are the crank and cam sensors, so it’s super important to ensure they’re installed, wired and configured correctly. Sensor Type: Hall Effect or Reluctor? A Hall effect sensor typically has 3 wires. Power, ...
Digital Hall Effect and Optical Sensor Types
The second type of sensor found of crank and camshafts known as a Hall Effect (this includes optical sensors) sensor. This style of sensor has a transistor and some electronics built into the sensor itself and will generally require a power supply ...
Trigger Wiring (Crank and Cam Angle Sensors)
The most critical sensor on the engine is the engine speed sensor, without this sensor the ECU would not know that the engine is moving and therefore it would never fire a spark nor inject any fuel. The ECU gets information from the crankshaft and ...
Nissan CAS – Facts and Fiction
