How to Test Crankshaft and Camshaft Position Sensors

You can tell when someone truly understands a subject because he can explain it in layman terms. Well done and thanks for the channel.

Let me say you are extremely good at explaining things and in a reasonable amount of time. THANK YOU for not telling a story about your girlfriends dogs new trick when I went there to find out how to fix a flat. All made up however if you want to give information to assist people who may not know just do that. I think you are the first person that has been clear to the point and not confusing. I am very well knowledgeable on automotive troubleshooting and your information is good and anyone should be able to to follow you direction with ease as well you cover all angles. I don't see how anyone could not comprehend your info even more so if they watch a couple times if new to the work. I rarely leave any comments check my profile but I feel that even though you may know you are doing a great job keep it up and more so all the people who are on limited funds that you are helping is awesome!

I really like the idea of being able to test everything with a basic multi-meter. This is great.

You are the man Mr Wrench! It's like family showing me how to do this because you don't miss a thing. Like for family sake.

Each used car I get and need help, your videos get me through it, and the advice is good on any model. Thanks for the lessons.

Finally a decent explanation. I have seen numerous videos on this matter. It all came together in my head after yours. Thank you.

Explained very well. Even an old school Holley carb guy and FI - ECU novice like me understood. Thank You!

Thank you for your quick and precise videos, you have helped me in many issues.

Very helpful video. Subbed! I will use this video to check out my dad's 2011 Altima. He said it went into limp mode driving to the supermarket this morning. I want to make sure he has a safe car to drive since he is 75.

Excellent info & teaching skills! Love your videos. Thank you so much for sharing your talents & conveying in such an easy to understand way for us laymen. Much appreciated by all!

No nonsense off topic crap that I see on other videos... straight to the point and no BS... thank you sir! Awesome videos!!!

Yes very informative video, I am replacing a sensor I bought today but now I will test both the ones in my porsche first

The three wire hall effect sensors can still be bad if you're just measuring the changing voltage. You should carefully measure their static voltages as well. You should put the meter on DC volts and measure the signal wire with the ignition on, but without starting it. The voltage should be in one of two states, High state (5 or 12 volts) and Low state (0 volts). If you turn the motor by hand using a breaker bar on the crankshaft bolt it will cycle through these two states. The important thing here is that when it's in its low state, that it is very close to 0V. If you measure something like 0.120 volts, it means that your sensor is failing and should be replaced. If this happens, you will get random misfires. You should also make sure the voltage is reaching very close to the source voltage. Put one probe on the source wire and the other on the signal wire. The difference should be very small, like 0.02 volts. With these hall effect sensors, you can do this check with a new one without installing it and using that as a baseline. Simply connect it to the connector and make the same measurements; you could put something metal like a screwdriver near the sensor to put it into an activated state. I had this same problem myself. The engine ran great but I had random misfire codes pop up. The CPS signal looked good on an oscilloscope. After replacing the wires, plugs, coils, power transistor and even cleaning the carbon out of the ignition switch I was still having this intermittent problem. I took a closer look at the static voltages of the CPS and that was the problem. It was measuring 0.162v on the low state. The new one measured 0.026v.

Great info! Land Rover Discovery 2 Crankshaft position sensors are notorious for failing... right in the middle of traffic.

this guy is awesome, he has lots of very educational videos. he has taught me many useful things

Thank you for the very detailed step by step explanation

Perfect!!! straight to the point with no long drawn out pointless/useless spiel. You do some great videos, thanks

Short and straight to the point. Great video. Thank you.

This video is more helpful than I can say. I'm currently having a crank-no-start issue and by George i cannot figure it out. Time to do these tests. I've got the 3-wire - mitsu evo 7. Thanks RAW. God bless you.

Just want to say thanks your video was step by step explanations were good and at a beginners level. You do a good job.
