How do you check a crank sensor with a scan tool?
Set up the scanner to read engine RPM and crank the engine. The scan tool should read between 100 and 500 RPM. A bad reading indicates that the crankshaft sensor isn’t working right. A reading of zero indicates that the crankshaft sensor has failed completely.
What should the crankshaft sensor read at 500 rpm?
If you guessed the crankshaft position sensor, then you would be correct. Set up the scanner to read engine RPM and crank the engine. The scan tool should read between 100 and 500 RPM. A bad reading indicates that the crankshaft sensor isn’t working right.
What do you need to know about Crank and cam sensors?
You’ve covered a lot of information so far, in this section I’ll get into the basic flow of tests that are part of diagnosing the crankshaft position sensor (and camshaft position sensor). Testing the crankshaft position sensors or camshaft position sensors requires that you test them in action, that is with the engine cranking.
What does the crankshaft position sensor signal do?
Since the Crankshaft Position Sensor Signal triggers the Ignition Module (or Fuel Injection Computer) to start switching the Ignition Coil Primary Current ground path On and Off… I usually refer to the sensor’s signal as the Triggering Signal.
How do you test a camshaft position sensor?
Therefore, knowing how to test them with a multimeter (or an LED or an oscilloscope or whatever) independent of a scan tool becomes very important. Now, when it comes to camshaft position sensors, a scan tool does come in handy since a bad CMP sensor does register a diagnostic code.
If you guessed the crankshaft position sensor, then you would be correct. Set up the scanner to read engine RPM and crank the engine. The scan tool should read between 100 and 500 RPM. A bad reading indicates that the crankshaft sensor isn’t working right.

How does the crankshaft position sensor work on a car?
As this reluctor ring passes at the front of the sensor, the CKP will create a magnetic field is interrupted, creating a square wave voltage signal that the ECM reads as crankshaft position.
What should I do if my crank position sensor is not working?
If the crank position sensor doesn’t return the values, then you definitely need to replace the CKP sensor for a new one. Once you have cleared the sensor, you can clear the trouble code and restart your car Test Pin Combinations are: To fix the engine from this error code, use a scan tool and inspect whether the engine is cranking or running.
