We have made this site easier to use and more compact that our previous web sites we have put in a search facility, this can be use to find O.E. manufactures numbers or using the advance search, engine codes.

The crankshaft sensor supplies information on the crankshaft’s current position, which the engine management system can then use to calculate rpm. These values make it possible to determine the most economical fuel injection and ignition timing for a vehicle.

Typical Hall-Sensor Circuit

To function correctly, a Hall-Effect sensor must have power voltage and ground applied to it. If the power, ground, or signal wire is open, the sensor can't operate. A short to ground on either the power wire or the signal wire also eliminates the RPM signal.

The Hall-Effect Sensor pick up from Camshafts and Crankshafts
Many of today's computerized engine control systems are using Hall-Effect sensors, also called Hall-Effect switches, to sense crankshaft and camshaft speed and position. These switches vary in design but are similar in operation. The main differences lie in the voltages at which they work physical configuration and location on the engine.
The Hall-Effect sensor is a very accurate way for a computer to "see" the exact position or measure the speed of a spinning shaft. Most designs utilize a shutter which passes through an opening in the sensor. The opening has a magnetic field passing across from a permanent magnet to the electronic switch. When the shutter passes through the magnetic field, it is interrupted and a change in voltage is sensed by the computer. With the shutter in the opening, the voltage falls to near zero. With the shutter out of the opening, the voltage rises to the specified voltage level. The Voltage changes between manufacture a signal between 0-5 volts is the most normal.

A Crankshaft Sensor is a component used in an engine to monitor the position or rotational speed of the crankshaft. This information is used by engine management systems to control ignition system timing and other engine parameters. Before electronic crank sensors were available, the distributor would have to be manually adjusted to a timing mark on the engine.
