I had this same issue on the same year of truck same make. I scoped it and checked relays and grounds since the customer was trying to fix it on his own. I thought it was the cam and crank sensor so i replaced both but they were aftermarket parts though. Didnt fix it. Was kinda weird was the u1000 code for can comm. If i erased codes the truck would start. Customer didnt have money to invest in OE sensors. I found a tip on ALLDATA where a tech removed the ECM and put it in the freezer to recreate the problem and narrowed it down to the ECM. Hard to make that call though. Cant wait for part 2. Thanks Ivan.
The use of 'No-lead' solder is the cause of many of these types of faults. The solder points will crack and/or separate from the pads or traces on the PCB. I had this problem with the clock in my Toyota Camry. I pulled the clock from the dash, took it apart and soldered all the attachment points that I could get to with 60/40 rosin core solder. It worked and has continued to work for many years.
Yes, no-lead solder has much lower ductility than regular old fashioned solder. IOW, it has much less”flex” (more brittle) and is more prone to cracking over time. Best practice is to remove ALL the old no-lead stuff and reflow with the good stuff as you did....
Bernie Thompson method: You too will become more successful in your bays! Great diag bro! Another tip to store in the back of my mind and that scope capture was flawless!
That was another awesome diagnosis, Nissan dealer would be selling you a new truck probably. Looking forward to the follow up to see if it solves it. You make it look so easy with your knowledge and tools 😁
Intermittent problems are so much fun. It reminds me of when a car I was working on had a failing crank sensor. The only time the car would not start was during a hot soak period. Like when you would stop for gas and only have the engine off for 5 minutes or so. The under hood temperature would go up causing resistance in the sensor to go haywire or maybe even completely open circuit. Changing the crank sensor fixed it.
You're very good at this stuff, personally I'd want to know if it's a marginal connection " aka faulty connection " you know I'm thinking green crusty at a connection somewhere
Great find Ivan, the CAM sensor signal is inverted at first then it changes direction, personally I've seen many Nissan CMP sensor's signal inverted with no issues or fault codes. Also I've seen Nissan CMP sensors start inverted then change direction with no issues or codes.
In most cases, no comm codes or U codes are indicative that the other modules are not receiving the correct information within the data from the ECM, not that communication is completely gone from the ECM. It is a thing that can send you down the wrong path when trying to diagnose while using non-proprietary scan tools.
..i used to deliver these engines when i was a Truckdriver, dedicated route from Decherd TN to Canton Mississippi to the Nissan Plant..well, Both Ends were Plants, just One Only Made the Engines..
That single problem with CMPCKP is what killed Nissan in the US. It was very common the overseas used car market rejected all Nissan, and that is why the incresed sales number in New Nissan did not show any increase in residual value
Great diag Ivan. Without a scope you would need a "parts cannon" the size of the 16" guns on the USS New Jersey. Even with a cannon this size, how would you know all the parts replaced were good? This Titan experience "make me wonder". Do the engineers at Nissan really know how their "creations" work? To your point. How tough can it be for the ECM to punch out a DTC when it has received a crank position pulse and no cam position pulse? You know the ECM saw it. It keep the fuel injector from pulsing. It nothing else the ECM the could have been programmed to capture "missing cam position count". Similar to a spark misfire count (Mode 6 data).
Just went though this with a 2008 Titan. You could jump it when it was cold and it would start and restart the rest of the day. Next cold morning no start without a jump. Ran through all the spark, fuel, injector tests and no injectors pulse. After checking grounds and fuse box related stuff I finally threw the ecu in the house for the night. Next two days it start right up with a low charged battery. Sent the ecu off and had it repaired for $100. Been fine since.
@@flintlock50 SIA Electronics. I went through their site on ebay since it was a bit cheaper than their website. Seemed to be a pretty common thing with nissans. I had a heck of a time coming up with the answer since I've drilled it into my head it's "never the ecu".

I’m so tired of seeing cold air intakes in the engine bay. It defeats the purpose people it’s called cold air intake for a reason it may look cool but it’s not doing anything for your engine it’s just sucking hot air back into the engine. Cold air intakes and KNN air filters god stop just stop
@@CedroCron Man you got that right. I despise K&N filters too. Used one in my trike, and after a thousand miles I found dust in the intake tract! One thing about the MAF sensor and K&N's is that if the user oils them too much, the oil does screw up the sensor.
Im pretty sure the position sensors also have a 5v supply and not 12v as you stated in the video. That would give really different signals when starting, ignition on or engine running.
Thanks for the insult. my experience is that not only cars from other dealers end up in my Bay. But also cars from independence end up in my Bay. Thanks for the insult
I had a 2014 frontier with bad cam sensor. I bought oem off of fleabay took ten mi n uses to change ran beautiful after that until i got the the cross contamination that took out the trans.
One could possibly have gotten in the ball park without a scope by doing your old fashioned way of first trying to determine if the problem was spark or fuel by spraying some carb cleaner into the intake then trying to start it. Some vehicles (not sure if it's this one) will fall back to a default strategy if either the crankshaft or camshaft sensors are unplugged (but not both) so that could be one's next test (also unplugging a MAF can be instructive). Much tougher on an intermittent for sure. When a module is in doubt reflowing it in an oven could eliminate the possibility of a bad solder joint or "tin solder hair."
Interesting indeed! Great vid, Ivan. I sure do miss the days when Japanese engineers PURPOSELY engineered parts so they COULD NOT be mixed up, or installed wrong under any circumstances! Those days are long gone, apparently. Imagine an identical, yet different sensor with the same number for different applications! This goes against everything those old time Japanese engineers stood for. I've come to expect this sort of thing from GM or FoMoCo, but it's looking like no brands are immune from the craziness today. All of it makes our jobs twice as difficult! Oh, I wanted to tell you, in April I'll be heading to FL for paramotor trike training! WOOHOO! Not at Aviator, but with PPG Gorilla, a little southwest of Aviator. He knocked $300 off the price for bringing my own equipment. SUPER stoked!! My friend Chris Fennimore (you might have seen him in the comments here and there on auto repair and paramotor vids) will be at Aviator getting trained at the same time, only his class is about a week longer than mine.

Great find! Too bad you couldn't see CMP signal during the crank NS. You were on to something when the INJ pulsed AFTER the cranking but not during. Yet with so much going on with goofy scan data, U codes, and then losing data etc, I kinda dismissed it to.
Experience would have you do a cam and crank sensor test for the symptoms this vehicle was displaying IE the crank, no start and (not sure if you picked it up) extended crank time when the engine was firing up. Great diag, Ivan, you would have been kicking yourself if you called the ECM as the problem.
@@PineHollowAutoDiagnostics yeh I know there is a part 2 coming, my point still stands though, it is usually the thing you don't check that gets you into trouble 👍
Could intermittent cam sensor function result from old engine oil or improper viscosity engine oil? Repeated cranking attempts would also lead to decreased viscosity (faster sensor response time).
It looked to me like as soon as you took pressure off of the key the engine still had enough rotation so that the injectors were able to fire before the engine quit turning. Because you were not starting the engine at that time the one cylinder that fired managed to have enough force to continue the engine rotation and actually continued running operation. Although you still may have a bad cam sensor the ignition system still had the system locked out until you took presdure off of the key and it was able to start like that for quite a few cycles until it got out of cam timing from the bad sensor every once in a while. That system has quite a few flaws in it. I have a 2006 Titan, why does the engine start having a ticking noise that turns into a knock? Do you know why the engine finally fails with these symptoms? It actually turned into a heavy knock before the engine finally quit altogether. I have not done anything with the engine yet so I don't know what happened yet. Have you ever run across this problem before? The engine just has 113K on it, it should have lasted longer than that. I brought the truck in before the 75K warranty expired for the same noise but all they could tell me is they thought it may be an exhaust leak. I think they knew what it was and just wanted me to continue driving it so that the warranty would pass.

Hey Ivan something I noticed I don’t think you didn’t noticed. At the very beginning the tach didn’t work during cranking. When you cranked it again and it started you could see the tach move right away. So does that mean the cam signals the tach?
I'm just curious it seemed like there was a release of the key at the last second during the cranking and at that point in time is when the vehicle actually started was that correct
I love the way you diagnose Ivan. I am starting a diag buisness after 5 yrs of watching , buying tools etc. Can you help me decide which to use, mitchellpro or aldata? It will be a slow start and the program is not cheap. Any suggestions? I have been buying single car subs so far. Thank you for sharing your videos and insight to all you guys out there doing this! Ps, 1st parts give me something to look forward to, the 2nd and 3rd parts! And the bonus footage is always priceless.
I've been doing the same thing although I find their diy sites to be lacking much of the information. Neither has rewrites on the diy sites. Some autoparts stores will give you access to data with a commercial account, others might offer a discount on sub services.
@@bradfaught1695 thank you. I am pulling the trigger and going to go with a full program, either mitchell or aldata.. Probably will go with aldata.. 175 a month.
Having used both alldata and prodemand, I prefer prodemand as it seems to have more info. That said, it is definitely clunkier to use. Our shop also has the version of identifix that includes service manuals, TSBs, sometimes different wiring diagrams than Mitchell. Service information is almost like scan tools - they can compliment each other and no single one has everything. The feature of identifix where other techs can post their diag procedure and you can see common failures is also a big time saver very often. Of course it must be used properly - as in you still have to do your own independent testing and verification - but it's great to point you in the right direction. They also have a similar estimating guide called MOTOR. They include Chilton's as well, but I consider that more of a DIYer's guide. Pointing this stuff out because I wasn't originally aware they had actual SI. If I could only have one, I would consider picking identifix over Prodemand even though I am a bit less familiar with it. It seems to offer more and be easier to use. I will point out one downside is that it is linked to IP address, so you're limited on devices. In the nature of full disclosure, I will also say it has been about 4 years since I used alldata regularly. Good luck on your journey!
@@ClaytheBMXer thank you very much for your input.. I have not concidered identifix, it is a pre set on my autel so i will research it now.. Thanks again !
@@raychad5058 No problem! Love my MS906BT by the way. It's slower than snap on and the graphing isn't as good, but I think it covers more for like a third of the cost. If cost wasn't a factor, I'd have every available scan tool and every available service information service, haha.
Hi I have Nissan frontier 2014 with trouble,some time when stop it (turn key off) at hot when restart directly in rang around 5 min start normally but after 5 min the car crunk no start for around 45min than start normally. Note When i put cold water behind engine at passenger side start normally I have changed crunk sensor 3time Camsensor both side Cooling sensor Fuel pump Fuel filter Sec. Trouble cooling fan not work .i make external relay but working only high speed. So any can help what do.and if any some problem before and he get solution.thanks
Hey Ivan, Could you maybe test if the Nissan Computer has a default strategy if the Cam sensor(s) is/are unplugged to see if it will start in that case? As ScannerDanner has proved in some of his videos, **SOME** ECM's are capable of starting the engine with just either the Crank OR Cam sensor inputs available and the other not working. My Recollection is that what some of these ECM's do is they Batch fire the injectors / plugs during the crank in various combinations, and when the engine does kick off and fire, the ECU is able to "Guess" where the engine rotation is, and the engine will run. Often in such case the crank is extended (ie several seconds while the ECM guesses) So i have to wonder if you deliberately set a Camshaft sensor fault by unplugging the offending sensor, if the the Donk will then run. Maybe you could test that for us?
I'm just thinking out loud...it was suspected that the vehicle started because all of the codes were cleared. Prior to clearing the codes you ran the fuel pump i.e. primed the system. I also noticed what appeared to be no rpm while cranking, but then started reading after the engine was running. Maybe that goes back to the cam position sensor issue? I think I'd want to try to catch it in the act again to try to rule out all of these "coincidences".
just had a 2007 nissan maxima today long crank time and a p0340 for bank 1 cam sensor. i scoped bank 2 signal nice square wave bank 1 had flat line battery voltage. new sensor fixed the problem
Ivan, I’m curious, I see you using the Launch scan tool a lot and the Snap On Verus a lot. What criteria determines which one you choose to use? I see Eric O likes his Autel. Right now I’m using an Autel MD906bt but am consider launch unit like your using in this video?
many things rely upon cam signal to actuate injection/ignition with correct timing. when in crank mode, many things are ignored for code setting and possibly even into short run time. yeehaw!
I have a 09 Nissan Titan it cranks but won't start I sprayed with starting fluid it'll start and run and I can go somewhere I come back turn it off and it'll start back up and if I let it sit all night it won't start I got to spray it with starting fluid again
@@neilmurphy845 To annoy people like you and me. I love Toyota BUT our Corolla had this alarm if you had seatbelt unbuckled...it sounded like a bomb was ready to detonate.
I will never understand manufacturers using dummy gauges for oil pressure. They wasted all the time to put a gauge and a light in there and then made the sending unit a switch. That is also a heck of a CAN delay for an 09
😎 video. I have always enjoyed them of recent since I subscribed Do you have any vids on transmission diagnostics of solenoids? Specifically p0744 on a RE4F04B transmission?
For solenoids I like to manually energize them and listen for a solid "click". Could also be a rationality code, which could point to internal trans problems.
Now that was an odd one, even you were thinking about the engine confuser being dodgy, but that was just a passing verbal thought. That vehicle has far too many sensors, they are acting like bmw with over complex systems. Imagine if there was a 20 channel version of your oscilliscope, you would be monitoring everything :-D. Now now calm down ivan ;-D
My 2007 Titan won’t start anytime it’s under 50 degrees unless I turn the key over and let it sit . The colder it is the harder it is to crank . Sooo ecm I guess ??
I'm always astonished by your ability to solve such complex electronic issues and dive into these diagrams. Your customers must be thankful.
Yep I’d be lost my existent of electrical is plug it in or unplug it lol

I love the way you diagnose Ivan. I am starting a diag buisness after 5 yrs of watching , buying tools etc.
Can you help me decide which to use, mitchellpro or aldata? It will be a slow start and the program is not cheap. Any suggestions?
I have been buying single car subs so far. Thank you for sharing your videos and insight to all you guys out there doing this! Ps, 1st parts give me something to look forward to, the 2nd and 3rd parts! And the bonus footage is always priceless.
I've been doing the same thing although I find their diy sites to be lacking much of the information. Neither has rewrites on the diy sites. Some autoparts stores will give you access to data with a commercial account, others might offer a discount on sub services.
@@bradfaught1695 thank you. I am pulling the trigger and going to go with a full program, either mitchell or aldata.. Probably will go with aldata.. 175 a month.
Having used both alldata and prodemand, I prefer prodemand as it seems to have more info. That said, it is definitely clunkier to use. Our shop also has the version of identifix that includes service manuals, TSBs, sometimes different wiring diagrams than Mitchell. Service information is almost like scan tools - they can compliment each other and no single one has everything. The feature of identifix where other techs can post their diag procedure and you can see common failures is also a big time saver very often. Of course it must be used properly - as in you still have to do your own independent testing and verification - but it's great to point you in the right direction. They also have a similar estimating guide called MOTOR. They include Chilton's as well, but I consider that more of a DIYer's guide. Pointing this stuff out because I wasn't originally aware they had actual SI. If I could only have one, I would consider picking identifix over Prodemand even though I am a bit less familiar with it. It seems to offer more and be easier to use. I will point out one downside is that it is linked to IP address, so you're limited on devices. In the nature of full disclosure, I will also say it has been about 4 years since I used alldata regularly. Good luck on your journey!
@@ClaytheBMXer thank you very much for your input.. I have not concidered identifix, it is a pre set on my autel so i will research it now.. Thanks again !
@@raychad5058 No problem! Love my MS906BT by the way. It's slower than snap on and the graphing isn't as good, but I think it covers more for like a third of the cost. If cost wasn't a factor, I'd have every available scan tool and every available service information service, haha.
Thanks for the vid Ivan. Very indepth diagnosis and it looks like the scope for the win again. So sorry this time it's parts required ;-(
Hi
I have Nissan frontier 2014 with trouble,some time when stop it (turn key off) at hot when restart directly in rang around 5 min start normally but after 5 min the car crunk no start for around 45min than start normally.
Note
When i put cold water behind engine at passenger side start normally
I have changed crunk sensor 3time
Camsensor both side
Cooling sensor
Fuel pump
Fuel filter
Sec. Trouble cooling fan not work .i make external relay but working only high speed.
So any can help what do.and if any some problem before and he get solution.thanks
Nice work Ivan. Thanks!
Hey Ivan,
Could you maybe test if the Nissan Computer has a default strategy if the Cam sensor(s) is/are unplugged to see if it will start in that case?
As ScannerDanner has proved in some of his videos, **SOME** ECM's are capable of starting the engine with just either the Crank OR Cam sensor inputs available and the other not working.
My Recollection is that what some of these ECM's do is they Batch fire the injectors / plugs during the crank in various combinations, and when the engine does kick off and fire, the ECU is able to "Guess" where the engine rotation is, and the engine will run. Often in such case the crank is extended (ie several seconds while the ECM guesses)
So i have to wonder if you deliberately set a Camshaft sensor fault by unplugging the offending sensor, if the the Donk will then run.
Maybe you could test that for us?
I'm just thinking out loud...it was suspected that the vehicle started because all of the codes were cleared.
Prior to clearing the codes you ran the fuel pump i.e. primed the system. I also noticed what appeared to be no rpm while cranking, but then started reading after the engine was running. Maybe that goes back to the cam position sensor issue?
I think I'd want to try to catch it in the act again to try to rule out all of these "coincidences".
Excellent diagnosis...!
just had a 2007 nissan maxima today long crank time and a p0340 for bank 1 cam sensor. i scoped bank 2 signal nice square wave bank 1 had flat line battery voltage. new sensor fixed the problem
Ivan, I’m curious, I see you using the Launch scan tool a lot and the Snap On Verus a lot. What criteria determines which one you choose to use? I see Eric O likes his Autel. Right now I’m using an Autel MD906bt but am consider launch unit like your using in this video?
That car sounds like an old alarm clock... and honestly, I prefer that to the usual "bong".
So what ended up being the problem because my xterra does the same thing in the cold but if you jump start it it’ll start fine
Was the cam sensor breaking down due to temperature variations? I wonder if it dropped out after engine warmed up to temp?
This was a fun one Thank You Ivan !
it couldnt just start on crank sensor ? if u unplugged cam sensor ? take long crank time ? then set code for cam sensor ?
seeing the single injector pulse. it looks very similar to a motorcycle spark wen the kill switch circuit is engaged
Interesting...
What scanner are you using that you using your phone to access
many things rely upon cam signal to actuate injection/ignition with correct timing. when in crank mode, many things are ignored for code setting and possibly even into short run time.
yeehaw!
So...did you replace the crankshaft sensor?
I think the owner is ?
Exellent passionate tech
I have a 09 Nissan Titan it cranks but won't start I sprayed with starting fluid it'll start and run and I can go somewhere I come back turn it off and it'll start back up and if I let it sit all night it won't start I got to spray it with starting fluid again
if you ever make another trip south going thru Alabama let me know have a ford that sometimes will not shut off
I would have cleaned that sensor first because there was no tach at the first start. Could have been frozen damp on the sensor or such.
What was with the 4WD DTC codes?
Great video, like the bonus tips!
Ivan nicely done,but Ivan why no pending code???
Exactly the right question. We'll see in Part 2 :)
Is it always winter there
Good job. What scanner are you useing?
Nice find Ivan . Pays not to jump from your basic tests first . Could have worked out expensive 👍👍👍
That Nissan beep reminds me of an alarm clock.
My wife and I have Accurite Atomic clocks...projects time on the ceiling...alarm sounds identical to the Titan chime.
@@mikefoehr235 I think it's the most annoying car sound ever
@@neilmurphy845 ya it is irritating
@@mikefoehr235 Why do car companies have those beeping sounds anyway.
@@neilmurphy845 To annoy people like you and me. I love Toyota BUT our Corolla had this alarm if you had seatbelt unbuckled...it sounded like a bomb was ready to detonate.
Since there are 3 cam sensors, how you know which one to replace?
The one with the injector pulse.
Yes dealing with one now lol. Have cheated with you in email lol. Except i do actually loose ecm coms . Its very frustrating lol.
Ivan! You are awesome! I wish I could ship my parts cannon'd Titan to you or fly you out to eastern Washington State.
I will never understand manufacturers using dummy gauges for oil pressure. They wasted all the time to put a gauge and a light in there and then made the sending unit a switch. That is also a heck of a CAN delay for an 09
Does that car have tack
When will you publish all of your notebooks? How to fix your junk 101... :)
What scanner software are you using? Thanks.
What scan tool is that? Looks like the thinkdiag? Been looking at that. Do you like it?
Launch Diagun IV. It kicks ass!
😎 video. I have always enjoyed them of recent since I subscribed
Do you have any vids on transmission diagnostics of solenoids? Specifically p0744 on a RE4F04B transmission?
For solenoids I like to manually energize them and listen for a solid "click". Could also be a rationality code, which could point to internal trans problems.
Thank you so much
Good one! Good information to have too.
Now that was an odd one, even you were thinking about the engine confuser being dodgy, but that was just a passing verbal thought.
That vehicle has far too many sensors, they are acting like bmw with over complex systems.
Imagine if there was a 20 channel version of your oscilliscope, you would be monitoring everything :-D.
Now now calm down ivan ;-D
thank you for the info
Nice. Video. Thanks 👍👍
My 2007 Titan won’t start anytime it’s under 50 degrees unless I turn the key over and let it sit . The colder it is the harder it is to crank . Sooo ecm I guess ??
crazy all the Nissan vids and no frontier loll
