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. How to Test an Inductive / AC Generator Crankshaft Position Sensor (CKP) This test shows how to test a crankshaft position sensor using a simple multimeter. Readings and pin designations may vary 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 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. How to Test a Crankshaft Position Sensor with a Scanner or Multimeter CKP Trouble Codes. If your check engine light is on, then your engine control unit (ECU) has recorded some sort of Cranking the Engine and Reading RPM. This next crank sensor testing technique also uses a diagnostic scan tool. You can test the crankshaft position (CKP) sensor with either a multimeter resistance test or a multimeter performance test. In this tutorial, I'll explain how to do both tests so that you can find out if the crankshaft position sensor is good or bad. Contents of this tutorial: Symptoms Of A Bad CKP Sensor. Where To Buy A CKP Sensor And Save. Updated August 01, 2022 The crankshaft position sensor measures the rotation speed (RPMs) and the precise position of the engine crankshaft. Ford Crankshaft position sensor (CKP) Without a crankshaft position sensor the engine wouldn't start. 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. 9bS0z.
