Magnetic pickup (MPU) sensors are devices which can be used in conjunction with electronic control modules for monitoring of parameters such as speed, direction of rotation and a variety of alarm conditions. %%EOF If you are using the 2-Pin Magnetic Pickup of the MSD to trigger the ignition, follow these steps. Turn the ignition switch to the OFF position. Check the air gap between the reluctor and the magnetic pickup. Verify that the cable length between the sensor and meter is less than 10 feet in length. In the two wire system – the magnetic type, you need to do the resistance test first. An object (target) of iron, steel, or other magnetic material, passing closely by its pole-piece causes distortion of the magnetic flux field passing through the sensing coil and pole-piece, which in turn generates a signal voltage. Still, you can use a DMM to test this type of CKP sensor in your vehicle. A Hall-effect sensor (or simply Hall sensor) is a device to measure the magnitude of a magnetic field.Its output voltage is directly proportional to the magnetic field strength through it.. Hall-effect sensors are used for proximity sensing, positioning, speed detection, and current sensing applications.. TROUBLESHOOTING. The sensor works using a iron cored coil with a magnet attached to one end. Plug the voltage input cable into channel 1 of the 6320. Using a Digital Volt-Ohmmeter (DVOM), measure the resistance (ohmmeter function) between the sensor terminals. When a peice of ferrous metal is moved towards the end of the sensor it changes the shape of the magnetic field in the coil, this changing magnetic field then induces current to flow in the windings of the coil resulting in a small amount of electricity being generated. Figure 1 shows the typical construction of a MPU. 1. The 3 wire speed sensor is externally powered, so you will need a power source of some form. Disengage the wiring harness connector from the VSS.
