    The Hall Effect Pick-Up supplies crankshaft and camshaft position reference signals to the Single Board Engine Controller (SBEC). The Hall effect device consists of a magnet and a Hall switch mounted with a gap between the switch and magnet. Rotating in the gap is an armature with windows and tabs. When a tab is in between the switch and magnet, the magnetic lines of flux are shunted through the tab increasing the effect of the magnet on the Hall switch turning it on. When the window is between the magnet and the Hall switch the magnet alone is not enough to trigger the switch. The digital output signal of the Hall effect sensor is then used by the SBEC for crankshaft and camshaft position reference signals. The Hall effect pick-up is located in the distributor assembly.

    The 91 dakota does have a crankshaft position sensor. There are two different AC Delco part numbers for vehicles with automatic transmissions; and a third part number for vehicles with a manual transmission. You can see pictures of them at www.rockauto.com. These sensors are referenced to the original part number; which you can get from a Dodge dealership's parts department, if you give them your vehicle's VIN (in the lower left corner of the dash next to the front window) and production date (on a plate on the driver's side door pillar). The parts person should also be able to tell you where the sensor is located. The information in the previous post sounds to me like it describes the ignition pick up; not the crankshaft position sensor.

    It is my understanding that the 91 didnt have a crank sensor mounted in the block,just the distributor pickup (hall effect) that is the cam and crank sensors...
    Read the description of how it functions....Thats why i posted that .....

    92 + had block mounted ones...

    Check with Dodge to be absolutely sure.....
