A hall current sensor produces voltage by means of the "hall effect". It is used in automobile applications such as wheel speed sensors, tachometers, speedometers and ignition.
It doesn't have a hall chip or a hall effect sensor, it has an inductive pulse cam/crank sensor. You can clean those.
The hall sensor can be found on top of a Volkswagen Passat engine. The sensor is placed under the valve cover next to the timing belt.
yes, located in the distributer.
As magnets pass a filed they cause a deflection a hall sensor will detect that
No.
The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular to the current. It was discovered by Edwin Hall in 1879
a current flow close to a magnetic source it influence the sources hall effect is a disturbed signal as a function of speed.
this sensor is inside the distrib.
heat, primarily. either causing degausing of the permanant magnet behind the sensor, or other thermal damage to the hall ic itself.
A hall effect sensor is a sensor that produces a square wave output that can be directly read and modulated by the ECM (as opposed to an AC wave sensor which produces a sine wave that must be converted). They are used as cam position sensors and ABS wheel speed sensors
Typical household GFIs are designed using cheap magnetics which would saturate given a DC leakage current. This means it will not be sensitive to a slow changing DC leakage current. a DC GFI can be made and does exist, but it will require a sensor that can sense DC flux without being saturated, such as a hall effect sensor chip.
in the distributor in the rear of the engine. sometimes known as a hall sensor
