Re: Way to test crank sensor?
A resistance check may or may not let ya know if the CPS is bad. Problem is that when the CPS gets hot it may show a different reading than when it is cool.
That is why you can drive your car, have it die due to the CPS being bad and then wait a while and the car starts just fine because the CPS has had a chance to cool down.
It's a $40 part. Replace it and see if the symptoms go away.
