Testing a Hall Effect Type CKP Sensor. Testing a Hall effect type sensor is best using an oscilloscope. But not many DIYers own one. Still, you can use a DMM to test this type of CKP sensor in your vehicle. And, unless stated in your vehicle repair manual, do not check the resistance of your Hall effect CKP sensor. You can test the inductive type sensor with a multimeter through the steps below: Unplug the CKPS's electrical connector and set your DMM to low-range DC voltage settings. Stop your engine from starting, then turn the ignition key to its "On" position. Connect your DMM's black lead to the ground and connect the red lead to each sensor wire. To test the crank sensor, you'll need a multimeter capable of testing continuity, voltage, and AC voltage or frequency. You'll also need to identify the location of the crank sensor, which varies depending on the vehicle make and model. How to test a 3-Wire Crank Sensor with a Multimeter? Here are the steps to test a 3 wire CKP sensor: Turn off the vehicle's ignition and disconnect the sensor from the wiring harness. Set your multimeter to the Ohmmeter setting. Connect the positive lead of your multimeter to one of the outer terminals of the sensor. You can easily test the crankshaft position (CKP) sensor, which is located near the crankshaft pulley, with a multimeter. No scan tool needed. In this tutorial, I'll show you how to do it. You'll easily and quickly find out if the CKP is good or bad on your 1991-1997 4.0L V6 Ford Explorer (Aerostar). 111. 19K views 2 years ago. In this video I tackle how to bench test a 3 wire crankshaft position sensor. This would probably work for any hall effect sensor as well. This came out of my 98 Ram To test the crankshaft position sensor, first, identify the type of sensor employed in the vehicle. Use a multimeter to test the voltage and resistance of the sensor. Remember not to test the resistance of the Hall Effect sensor. Connect the red lead of the Digital Multimeter to the reference wire of the sensor. Similarly, connect the other lead of the multimeter to the ground wire of the sensor. You will see 5, 7, or 12 reference volts depending upon the car. It means your ground and reference volt wires are Ok. 2xbju.
