How to Test Crankshaft and Camshaft Position Sensors
Вставка
- Опубліковано 22 лип 2024
- Here is how you can easily test both your crankshaft position sensor and camshaft position sensor. It's very important to be able to test these sensor since because they control your ignition and fuel injector pulse and if they fail they could cause a Crank No start condition.

You can tell when someone truly understands a subject because he can explain it in layman terms. Well done and thanks for the channel.
I absolutely agree with that statement!
Some topics are too complex to explain in layman’s terms... eg methods of molcular cell biology. But in this case I agree.
Sorry.But I dont understand how he test.I did not see where it he connect in outlet in AC in magnetic sensor.And in 3 wire also I did not where he connect it.Only reading I see
Q
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.
Brooo my mind just fully unlocked my missing key to understand how to diagnose electrical problems
Thanks
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.
Where were last week?
What about if i only get 4.996 volts as i rotate the engine by hand? Means the sensor is stuck in one position?
Wow! Good info, much appreciated!
Great info! Land Rover Discovery 2 Crankshaft position sensors are notorious for failing... right in the middle of traffic.
Crank and cam position sensors generally are notorious for failing, but let's be honest, Land Rovers are notorious going back 30+ years for electrical reliability (well, lack of to be more precise). Long may it continue (and it will)
this guy is awesome, he has lots of very educational videos. he has taught me many useful things
chrisvill54 me too
I agree he is a great teacher
Cool
I'll second that!
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.
You are a life saver. I have a 06 Subaru inpreza 2.5 turbo and it was breaking my head for 3 weeks. Thank you. You have no clue
Great video. I find that alot of problems can be made easier with a good diagnosis method, like yours :)
Thank you very much for another informative video. I see it’s 8 years old, it’s like you recorded it yesterday! Simple and to the point!
Thank you.. You are a true subject matter expert. No guessing on a three wire.. Simple test.. wire, crank, scan the multimeter for a voltage signal.. Thank you.. Thank. Made it simple.. Have a great day..
You're a life saver, great videos and easy to follow
the best i have seen, and i been working on cars most of my life,thank you
This is so clear and helpful, and short! Perfect video thanks R&W!
you explain things so easily thank you..cannot understand why anyone would give a thumbs down when this is so helpful.

Probably people that can't comprehend anything past a 2nd grade level.
martinguitarhd28 they are jealous and loser
I replaced my 2003 sprinter cam position sensor, works better than ever, I had crank but no start issues when the van was hot. $20 part with only 2 bolts.
i found this video by accident however it is useful for ppl who dont know what they are doing or are doing general repairs on sensors. great explanation.
I like your mc patch.
Bro straight up thank you so much. You literally explain it super easy.
You always explain in Great detail thanks for your hard work
you are amazing at explaining complex German automotive techs
Someone just made one of the best videos i’ve ever watched... Well Done.. you know your beans.. cheers
Thanks for the information in this video and others. A lot of mechanics won't tell you this stuff so you'll have to go to them for overpriced repairs. Thanks again and keep up the great work.
Sometimes repairs are expensive, not always intentionally overpriced. It costs a LOT in overhead to hang a shingle out and open a legit business. I can't ask a guy to give up his day to fix my stuff for the same price I could and make no money to pay the light bill, taxes and tool truck bill plus house and feed their family on short days when they get home by dinner. They won't be around long. There are scalpers out there and I have no defense or respect for them.
Cheers!
Straight to the point and simply put. Thanks
Thanks man. I like your posts and videos on automotive. You really make it simple and i can tell you know your stuff. 2 thumbs up.
👌you as a teacher is incredibly easy to learn your methods; thanks 😁👍
Very informative video. Thanks for posting 👍👏
Thanks for taking the time---very helpful
Best video I have found on this topic! Thank you very much! Liked and subscribed!
Oh, wow, at first I thought this was the typical "mechanic in his garage"-type video which, while quite useful, are usual really low quality and mostly talking (and a ton of noise in the background) and little showing, but this is really high grade with a bunch of stuff prepared beforehand to teach us better. Good job!!
Great video Very informative explained very well thank you !!
Awesome video, watched til the end. A little slow and basic for my liking, but love your efforts explaining it correctly.
I am curious to watch more of your vids.
Great, nice detailed explanation! Awesome!
your a great teacher. thanks. youve helped me loads :)
can you make a video showing how to set up the back probe ground for the 3 pin sensor?
Indeed, this guy is good, his videos a vey educational! may tnx , Man!
you videos are the top of the line!!!!!!!!!!you are a amazing teacher!!!!!!!!!!!
Fantastic job explaining to us/ME and educating me with what I need to know while I'm troubleshooting my damn car.
Very Helpful! Thanks!
Good job Sir .. your a blessing to us DIYers
Nice video bud i know it's an old one but has helped me test mine as been having problems with my vxr ;)
Your the best u put this out so good love it every much am all the way out in Jamaica thanks for your help a lot
Good lesson. So do u know how to check also ECU with Multimeter?
Great video! I'd like to add that some crank sensors with produce voltage and can still be faulty if it is not being pulled all the way to ground, but you would need a scope to see that, cheers!
ferlan 9 so if it's giving signal voltage reading back to the ecm, how can it be faulty?
Dude you are awesome. Just had say. I agree you're gift is in teaching.
dear sir your way of teaching is outstanding and thank you do much up loading videos best regards
Very well explained, this will be a big help to people as i have learned from it,thanks.
Great job dude! Excellent video.
Excellent video clear and concise explanation that the layman can understand, well done
excellent video there partner!!! thank you for sharing....
Thank you. You do a great job.
he is so easy to understand the way he explain things u just get it !
Awesome video thanks for explaining!
Great description on how to test the CPS.. thanks!
looking forward to more stuff from you for testing with dvom
the picture quality on this video is excellent
Excellent video thanks
Thanks friend for all your videos and help. I have a 2000olds intrigue. And i might have to replace crank sensor . But i also need to do a relearn . What kind of scan tool can i use that can program relearns? Any suggestions as far as brand or type ? Thanks
Well done, good info, easy to follow. This is very helpful, thank you.
Love those Jags, always wanted one as a kid..
I have subscribed to your channel do to a very deep appreciation of your knowledge and delivery sir.
Aloha,
Stanley
An absolutely superb video.helped me loads thankyou kindly.great work sir
great video !!! i have a problem with my expo 94, the conector is different, in the car has square conector and the cps is triangle... how can i to know wich is whit wich... thaks for your help... best regards...
Great expansion on the subject I am now much wiser on this matter Thank You
Really Helpful Thank You
EXCELLENT video. Thanks!
I am getting a ground reading on 2 of the 3 wires. Does this explain that there is a short somewhere?
what does it mean with metal shavings on the
crank sensor ? 92 Dodge Dakota 3.9 l
Great info. But when these sensors warm up, can be a fail.
Do you recommend a mileage replace for these parts, b/c lets face it, nothing lasts forever
Any ideas on what would cause starter kickback during cranking? My CPS is new, but I'm wondering if the spacing is correct on it since it is a hall effect type sensor. Absolutely every sensor on the 94 Ranger has been replaced, and I mean every single one.
Excellent video by tony as ever
So the second sensor he tests, when he puts the paperclips on it are we assuming he plugs the sensor back into the car but doesn’t connect the pins to the wiring harnesses since he has them hooked up to his tester unit? Or does he hook it up to both his tester unit and the cars wiring harness?
Thank you Sir for the video very easy to understand they way you have demonstrated it.
Nice video. Even explains how it works.
Love your videos
Very insightful
hello sir do you have any idea what sensors are used for a portable test rig to balance crankshaft
Hi, I have a 1996 lexus ls400 crank but not start, does my car have crankshaft sensor and camshaft sensor or just one?
Nice job explaining the differing voltages from the 2 wire sensor. This is what I needed to troubleshoot a problem with a new cam shaft sensor that appears to be faulty. I am at my wits end in getting this car figured out. As we know it is not always good to buy cheap parts which was the case on this car. I bought the cheapest cam position sensor sold on ebay so after a no voltage test as you outlined in this video I returned it and ordered the next more expensive one from a different manufacturer. All a person can do is get money back for the bad part. It does not cover the agony of going to the next hours trying to troubleshoot the next potential problem that might cause the car not to start. On a 97 MB E320 this could be a number of items which all relate to no injector pulse or a no start condition. THe question arises what sensor triggers spark and which one triggers injector pulse. Is it the crankshaft sensor or the camshaft sensor. Guess I will wait till the new sensor arrives to be sure. Next if this does not work I go to retest the crankshaft sensor which is also new and a bugger to get out. I have spark cause it runs if I put gas down the air inlet port to the engine. Have you run across a situation like this one? Thanks again for sharing your expertise. J
Thanks for the lesson I learned something new
Thanks so much.. that was so easy.. today with my friends car, I can come out looking like a "super hero" Yay! Thank you.
Thanks buddy nicely explained.
thanks! i recently put in a NEW (but bad) CKP sensor and its apparently shorted internally- screwing up my fuel level gauge, ignition coil/ignitor(?) and setting off a host of other selonoids- et al! I cleaned all grounds, rebuilt my fuse box, new ECU, cleaned everything........no changes UNTIL i just now decided to swap back in the old CKP sensor. All the electrical clicking, etc went away immediately and Im not going thru the KEY RELEARN process for the new ECU.
Could either of these cause a multiple/random misfire, although the car runs pretty good yet? Working on an Acura TL Type S 3.5. Thanks.
Thank you very much. Your video was very helpful
Thanks man that helped me out alot and saved me money 💰
When you test the 2 wire camshaft sensor, do you have both points connected? When ran the cam pulley to get the readings.
Thanks so much well demonstrated
