- The camshaft position sensor is almost a misnomer. Its rightly referred to as the cylinder identification sensor. The crank sensor is used as an rpm sensor that is as a rev counter, this sensor is used for ignition spark computations. On few cases it can be used for both spark and fuel injection.

Thank you so much. Nissan quoted me $150-$200 for the sensor and 1 1/2 hours labour. A ball park figure of $400 plus over the phone after I rang them when roadside assistance told me the error code was for the crank angle sensor. I watched this video and bought an aftermarket sensor on special from REPCO for $35 and put it in the following day after work. Took me about 1/2 hour. Very happy, cheers :)
you are welcome :)
Glad it worked out for you. I had the same issue in a T30 Xtrail back in Dec 2016 immediately after purchase. I think the $400 quote is a little steep. I bought the newer metal OEM sensors for $80 each AU and got mechanic to install for another 160. total $320.
I wonder how many km you got out of yours before they failed. I'm trying to figure out the approx age, Km of my engine as it's 2nd hand. Cheers
Just completed this task. My car had been using stacks of oil, over a 1L per 100kms. A couple of my plugs were oiling up, and I thought this was the reason for the misfiring. Had the engine replaced due to the oil consumption. Afterwards, it would still misfire occassionally. My OBDII unit indicated a pending error with the Crank Sensor. I surmise that I actually the oil consumption and the misfire were 2 different problems.
Replacing the sensor was easier than the impression I got from reading a few of the posts. As some say, the key would be to remove the bracket under the throttle, and I used a small step so I could lean into the engine bay at bit easier.
Thanks for the video. Its nice not to have to figure it out from scratch.
Thank's a lot for this video.Just a note about the Crankshaft sensor. For me, it's easier to unplug the sensor after disassembling it, and reconnect it before reassembling it.
yeah that is what i did. much easier
I disconnected it before removal because I wasn't sure if it would interfere with getting the bolt out. But I did connect it before installing the new one. Can't believe how easy this job was.
I just replaced the starter motor, .... now wished I had replaced the firewall sensor while at it. I did not see it at the time, though no codes present. Informative, and Thank You.
saves me money on labor cost at repair shop by replacing the sensors myself by following the easy to understand instruction.
You are welcome
Many thanks. Very helpful. Mystery dispelled. What I find hard to accept is that a mere sensor, a detection device, can actually cause an engine breakdown, or even an accident, e.g. in the middle of overtaking, instead of just providing information that there's a fault. Old cars never had such troublesome sensors. They broke down for other reasons, I know.
They break down because as was with my car, after 3 fault signals on the same code, the engine cuts out .. In order to get it going again you either have to run a scan and delete the codes you fill the engine OR, as I also did, disconnect the negative battery lead for a long time, which caused everything to reset and show restarting the engine...
I just wanted to give you a big thanks for the brilliant video which allowed me to get a top sensor and replace it up literally only took 5 min, and confirm that it was the faulty one.. (thanks for the pic of old and new type sensor and min was the old and the new one was .. Well... New type!!)
FYI, the old sensor caused my motor to sound and idle rough and gave the exact error codes you showed and caused my motor to cut out...
We're up and running and I saved at least $200 from garage costs... Cheers!
For me, this was the most helpful video out there, bc it actually shows the position the sensor, which can only be located by feel. And although it shows removal of the filter and associated tubing, what is doesnt show is the whole bunch of pipes that are in the way of reaching in to remove that bracket, and then reaching beyond to the sensor location. Perhaps he removed them in advance. Anyways, I was confused and disoriented by this for half an hour, b/c it looked so different. In the end, I did not have to disconnect any more tubes, but was able to reach through them with some difficulty. Whole thing took 2hrs, and now my car starts well!
I haven't removed any pipes at all to access the firewall back sensor. It is exactly as I have filmed and happy that you get the job done :)
You can see it easily if you remove the engine cover and look down between the valve cover and the manifold.
This information is healthy. I used to get this problem and now am happy with my Nissan ex trail.
Thanks again, done this job twice cause I used a cheap ebay replacement sensor. Only lasted 18 months. The bracket removal is the key to finding the CAS. Thanks again.
The best explanation and illustration ever. It’s true, this is an easy way to learn.
I had to change Cam & Crank sensors today. Your video helped me to locate the Crankshaft position sensor. Thanks a lot mate!!! 👍👍👍👍👍
Very useful video. Its very cramped around the crankshaft sensor so to create more access space it is a good idea also to remove the bracket beneath the throttle control actuator too
Literally just finished doing this on my 2006 nissan x-trail and this video was a big help! The lower sensor behind the engine was terrible to get out but I managed to get it after several attempts to pull the sensor out. I had to take a small screw driver and wedge it in behind the bolt nib to pop it out. Not easy as you have almost no room for leverage. It is done though and thanks for the video! Car started without any issues after the replacement of both the cam and crank shaft sensors.
Thanks for sharing your experience :)
Many thanks. My xtrail is sorted out
you are welcome :)
Thank you for the video. This is extremely helpful and I'm only out $125AUD for a pair of sensors, and 30 minutes of my time.
Glad it helped
fantastic vid,, I fitted the unit without any problems well put together
A professional way with easy steps and also excellent video recording to show the adea..thanks
Glad it was helpful! Thank you :)
Thanks for sharing. You shot very professionally. Descriptive and informative. You solved our problem by watching your video. Rize Turkey '
Greetings from. Thank you so much.
I am glad that my video was helpful to you :)
ok thank you the video really helped me to repair my own car 👍👍👍
Glad it helped
awesome video! definately will subscribe. please keep posting xtrail repairs....thank you !
Q, do you HAVE TOO replace both to and bottom sensors?
I only replace the top sensor as I couldn't really get to the bottom one, but my car started and sounds smooth...
ألف ألف ألف ألف ألف شكر وتقدير على تحليل
Thanks for that video. It really helps a lot but tell me where did you get the parts?
Is both of the sensors identical?
Because they look so
Just a question. Can you do it from underneeth the car easier?
Did the trick.. Thanks mate
What maybe be the cause if the temperature gauge is not working. Nissan X TRAIL T30 QR20?
Cery useful video, thx
Have 2003 x trail it's long cranking when sitting for couple of days and puff of black smoke when started is it fuel side or these sensors??
Very good and useful video, THANK you
are the cam and crank sensors the same and are interchangeable? you had 2 in the box and it looks like it didn't matter. you just grab anyone from the box. thanks
yeah, they are interchangeable, so you can fit any of them, both are exactly the same.
Are both sensors the same. Thank you.
I have ah problem with my Nissan Almera car starts and idle but no acleration what is causing this I have change all the sensor already and the number 3 coil pack and still have the problem need ur help please
Thanks a lot for this video! Very useful!
You replace the crankshaft position sensor from the bottom of the car?
No, I have replaced from the top of the car. I couldn't get access from the bottom.
It can be done either way I've found
very difficult either way
I have a question I have a 2006 Nissan Altima an we replace the crankshaft position sensor an camshafts sensor the start but take a long time cranking the start why is doing that
Did you ever find out? I have the exact same 2.5L but I replaced both but it doesn’t want to “turn over” but it will crank. I’ve replaced spark plugs, ignition coils, fuel injectors, & both cam/crankshaft sensors 🙄
i have issue where cranks but wont start no fault codes for crank or cam sensors
Thanks for the video, mate.
Could you tell, what kind of lubricant you've used to grease the sensors before installing them?
Thanks very useful
I should have mentioned in my X-Trail. LHD 4WD.
Nice and informative video, i got a nissan xtrail 2007, motor QR25DE, wich will be the parts number of those parts
I fitted new cylinder head gasket nd dnt net to start fire is feeding nd feul
Thank you this was helpful, do you perhaps know how to reset the engine fault light after the installation of the sensors.
I just disconnected the battery for 2 hours and it was reset by itself
You can also purchase a ombd reader for seeing what the codes are and erasing them.
I got the same problem. Almost ready to reconnect the battery. But if disconnecting the battery for 2 hours isn' helpful, you could always call roadside assistance to clear the fault. Heck, that's why we pay the annual fee.
I have a qr 2o English 2003 an it is nat starting an I don't now what to do please help me I love that Nissan car get form my father
Whats the small hose to the left of the big hose you are unclamping at 5:36? I think I found this hanging after changing the crankshaft sensor. What does it say on the hose?
Thanks much you always be great help to me
Happy to help
Sir,my my nissan xtrail t30 dosn't accelerate normally,i change the pedal accelerating sensor but nothing happen,then what is it?please give me an answer thank you
Great Video. I have a different model (P12 with CVT), but with QR20.
Isn‘t it easier to reach the crankshaft sensor from underneath the car?
Or is your way the easiest and only way to replace the cranshaft sensor?
I have a p12 as well and it keeps stallibg and once engibe warms up very difficult to start and misfires scan told me it was the crankshaft position sensor did u get it sorted ?
Thank you very much pro
I have massive rpm drop in my nissan altima 2017 when I release gas padel or when I turn Ac on with no fault codes in all computers... cauld it be these sensor? or it should appear a fault code to be sure? help me please
Happy new year everyone here , anyone please helping me the location of cam sensors exactly where the place on engine?
From the top or from the bottom of engine?
thanks 🙏
How do I replace the crankshift sensor for a 2002 Nissan Xterra 4wd v6? Thank you!
We don't have this car here. This video is for QR25DE engines only. I'm sorry that I couldn't help!
i have the same engine, it only starts when i disconnect the camshaft position sensor. when it starts then i plug back. could it be the camshaft sensor be fault or its something else?
Generally speaking, the car should not start and run normally without the crankshaft sensor, I'm sure your engine probably started in limp mode. as crankshaft position sensors are used on all modern cars to determine engine speed and fluctuations.
So, when you started your car by that method, does your car runs normally without issues ?
@@ezy2Learn Hello, Thanks for your video. I have the same problem and when I disconnect the camshaft sensor, the engine run normally (limp mode). I have changed the camshaft sensor but not the cranckshaft, should I change both in the same time ?
May know what type of 'reader' you use to detect both the error code. I want to get one. Pls recommend? Thanks
Getting confused, rockauto has both camshaft and crankshaft sensors from Standard Motor Products as the same part number - PC464 but each is listed with different prices. Update - they are the same part number and the prices are the same.
That's true, both are exactly the same sensor. They just installed in two different areas :)
@@ezy2Learn Got the part. Phoned my local mechanic and he said could take up to 2 hours/$250 to install. Should I try myself first?
@@uvid4us sure yeah, it is not hard to install them.
OK, did this today finally. Took a few hours but now I could do it in less than one. I googled while I was struggling and on another Nissan, they suggested to remove the engine cover. Well that made a big difference. I could now see the sensor bolt and my fingers thru a slot with a bright flashlight, so DO remove the plastic engine cover. You have to shine the flashlight down the same vertical slot that you look into so it's a bit tricky but it really helped to see what was going on. Also, unplug any electrial connector plugins that are in your way, that really helped too.
@@uvid4us Mine has no engine plastic engine cover, I assume your car is a new model :) I am glade that you have done it yourself and saved $250.
Thanks now all sensors are working from test but consume fuel drop in speed and smokie. well locally we suspect the turbo, if it is the turbo how can we fix that. thanks.
best regards
If you have problem with turbo, first thing you need to check any buildup inside it. I don't have turbo car but I used to clean my turbo using air pressure and never had issue with it.
Excellent
Hi. My car model is nissan presage 2.5 and the problem is, my car can't move in all position gears (R, D, 2,1).. what is the problem? Tq fir helping.
What year is Altima, and engine size? I got a 2010 2.5L When I look there is camshaft at top near SP #4 and other one lower at the corner near bottom of engine and crankshaft is all the way back of the engine, cant see it.
Hi with your new sensors is that interchangeable the cam and cranks sensor?
What is that bracket even for?
I did subscribed.
Thank you for a nice video!
Good job 👏
Is it possible to get to the crank shaft sensor from under the vehicle?
Should I turn off check engine light after changing?
Yes
I can put the other model you put in your video...it is not necessary identical??
Is the cam shaft sensor and crankshaft sensor are the same?
Yes both are the same
Thanks 👍
Wich sensor is for the speedo?
The Physical hose arrangement appears to be different from the Altima car to the XTRAIL. There are a few hoses that I don't see in this video and the interfering clamp. Do you have any additional pictures to show how to access the sensor? If it is accessible better from below?
There is not option here to upload extra photos.
@@ezy2LearnYou could add to your video as slides in the end.
Could you share the part number of the sensors, greetings from Panama
Also, with I bought new sensor type which had the connector on top Just like your video and It wont start, but with the old one (Faulty one) it did
I have replace both sensors and the engine dosent start, what can be?
I changed the sensor as in the video, but nothing has changed. There is still a cutoff when changing gears, and the car suffocates when the accelerator pedal is quickly pressed. Can you help please?
You need to change both sensors NOT just one sensor
why is one sensor round and the other square will both fit?
Do I need to reset the ECM once the sensors are replaced? Because I just plain replaced the sensors and the car only cranks and wouldn't start. Also I get a check engine light that points P0340.
If you are getting P0340 then, your cam position sensor is not installed properly or harness wires are discounted somewhere. Please check your harness with a multi-meter.
Hello , I was able to drive more than 50kmph, Therefore I changed the camshaft crankshaft sensor as per recommendation of a service adviser. After 3 months , I got the same problem , the vehicle is not moving more than 50kmph , oil comes out from the air filter, oil goes to the injection and black smoke is coming out from the engine (Nissan X-trail year 2005)
Sound's like you have blown head gasket
Mass air flow sensor is bad
so here's my problem.Both camshaft and crankcase sensor were both replaced 2 years ago with duralast products. I purchased at Autozone and they were lifetime warrantees but now I have the code again of crankcase pos sensor error ....btw I am told they are identical parts,is that right?anyway, my mechanic replaced them again and as soon as he restarted the car, the code came back on...and car symptoms continued. He suggested using dealer parts, not duralast.but it strikes me as weird this would happen so quick. he also said something about "initializing" them. I have not read that this was necessary. Anybody have any ideas?
Hello. Thanks for the video. pls. i have nissan 2003-2.5. the old sensors are 2 the same and plastic design, so now if i want to change, you prefere to replace them with sensors(( metal design )) or plastic ???? wich is more powerfull the sensor with plastic design or metal ?? many thanks
Plastic design is the oil version of the sensor and it is not as good as the new metal design, so please replace both with new the metal design version. Thanks
@@ezy2Learnok Thank you

Thanks much again God bless you
I bought 3 new sensors but is lose have to get the part from the dealer? I end it up putting back the old one cuz the car loss power aslo old one fit perfectly the others was small what should i do!!!
Did you purchase the correct sensors! it should be lose fit only if the sensor is missing the its gasket! otherwise it should be pretty tight.
Does anyone know where the crank shaft sensor is for Nissan vanette?HR16
Is the crank shaft and cam shaft the same for 2004 Nissan xtrail
Yes the same for 2.5L engine
@@ezy2Learn thank you
@@ezy2Learn my 2004 xtrail keep jurking when driving do you think it has anything to do with the sensors or my spark plugs and coils
The most common reasons why a car jerks when accelerating, because your car's engine needs both fuel and air to do its work. A block in the fuel line or air intake or faulty Spark Plugs coils can make the car jerk during acceleration as it loses one. So you will need to do few checks on your air filter, spark plugs and fuel filter and it should be one of those.
hello sir gdpm, by the way i have nissan xtrail t30.. i change alternator,starte,battery, almost 1year..but now got problem lastweek battery blinking,.i still use the car..after that cant start up..i call my buddy to jump up the battery..almost 3km run engine stop.
How many km on the clock ?
I got the error p0340 and the guy said it was the camshaft sensor which I bought, do I have to also change the crankshaft sensor as well? X-trail t30 qr20de engine
Yes, please change both sensors. The old version (black sensor) is not good as the upgraded version.
Should I fit new sparkpugs
Not related!
can you give me part numbers for both sensors ,thanks :)
Both sensors have the same part numbers as they are both exactly the same :) the part number is B23721-6N21A
thank you so much !!!

Hi, I have a 2011 Nissan Diesel X-trail, When I start the engine cold in the morning, it runs for 10 seconds and then stops. after about a minute of turning the engine over it starts again. On two occasions so far the engine has stopped while I have been driving, In your opinion could this issue be caused by a faulty Cam or Crankshaft sensor?
Crank
I have nissan x-trail, t30, 2004, QR20D, issue massive drop in RPMs while driving when i did a sudden brake. I have to stop aside turn off the engine and on back again OD flashes 15 times. After that turn off and on again, and start the engine, rpms back to normal and drive back normally. Could it be the same issue? Some says it is speed IO sensor? Need your kind advice on this. Thank you.
Sounds like my problem exactly! if your car 2004 then most likely you have done more than 150,000km which over the lifespan for the original plastic camshaft and crankshaft sensors. You can get your car scanned using OBD device to get the error code, if you get error codes P0335 P0340 then you definitely need to change those two sensors.
Same experienced here, i got 2006 mod with QR20 engine. it cranks normally but after driving 16 km and have it parked for 10 minutes the trouble comes. I have it cranked many times but engine is not firing , checked engine (yellow) on my dashboard. Could it be the same problem?
Felicidades
is this the same for a nissan xtrail t31?
Yes
Hello there can you please help me I did change the camshaft position sensor bout of them and the alternator the light check engine is gon but when I drive my truck still loosing power and shake specially in the trafic light's is 2005 f150 can you please help me
Hello, your problem is fuel or spark plugs. You will need to check your fuel filter and replace it if required, if fuel filter is good, then it could be your fuel injectors need cleaning, try to use fuel treatment that is designed to clean fuel injectors it is around $3~$5 a bottle, and of course check your spark plugs. Let me know the results. Thanks
good afternoon, can you give me the colors of the connector wires that goes to the ckp sensor of the Nissan qashqai?
Thank you
I don't have nissan qashqai
I want to know what's up with my car. I have a nissan x-tail diesel it does not accelerate.
Very hard to tell without inspection, but try to clean fuel and air filters, they do make huge difference in diesel cars.
Will a bad sensor cause the x-trail not to start?
Yes, but you need to clarify "Not to start". Does your starter motor works and does it turn the engine ?
Hello...qestion i have nissan primera 2005 p12 whit p0335 and p0011 code.the engine is qr20.
Is it the same as in the movie qr20 de engine?
QR25DE is 2.5L and QR20 is 2.0L , I assume it is the same, I can't verify!
