Crank No Start Nissan Titan

The Owner of this 2008 Nissan Titan had a crank no start and fired the parts cannon at it with a crank sensor and then a cam sensor. Still a crank no start he had it towed to a shop that verified the wiring to the crank sensor was good but had no coil fire so they called me in to pinpoint the issue.

[@anthonydixon9908]

As a former engineer with Nissan North America, (Smyrna Tennessee) I tell everyone who works on Nissans /infinity to use OEM parts the tolerances are very specific and most aftermarket gets close but not close enough , great job 💪🏿💪🏿💪🏿💪🏿

[@autodiagyt]

Why do they not code the u codes better lol. It's always a generic u1000 and never a specific way to identify what module lost communication. It makes intermittent can bus faults extremely hard to diagnose.

[@gutrali]

​@@autodiagytThe answer is always $$$$. In this case I'm sure the decision was made higher up to force more revenue through dealer service and part departments

[@HouseCallAutoRepair]

It took me 4 sensors, from 3 different sources, to find one that worked. (and the codes were switched between cam and crank) The one that "fails" is the one that's making the "difference" during operation. Crazy and annoying logic.

[@ikocheratcr]

I would understand the tight tolerance talk for bearings, rings, valves, etc. A cam or cranck sensor, no. If it is reluctance, hall or magnetoresistance, all of them can operate at big distance (3~5mm) without issues, and even provide reliable detecting with changing distance +/- 2mm.

[@pavelkutishchev5551]

It’s not only Nissan, pretty much all brands if it comes to sensors, always highly recommend to use OEM especially EU cars.

[@spelunkerd]

Gotta love how thorough you are at verifying your diagnosis. As you clearly show, it's not very difficult to prove that wiring and even the module is fine. The bonus was when the new sensor didn't work straight out the box, air gap, ha ha.

[@DuaneDonaldson]

Bernie Thompson training, as the air gap increases linearly, the signal weakens exponentially. Wish you had time to put out more videos Brother, cheers.

[@mikechiodetti4482]

I agree. With aftermarket electronic parts it's 50/50 at best. However, what do you do when the OEM says "No Longer Available???" Then it becomes a hope and a prayer. Good one Jake.

[@nexx2012]

I had the same dilemma 2 weeks ago where on a Nissan Armada the Camshaft Position Sensor was failed. I pulled out that Plastic Square style Sensor. Went to the dealership and asked for a Camshaft Sensor via the VIN and they gave my that metal barrel sensor, the package even said Crank Sensor but counter reps confired it was a labling error but it indeed was the Camshaft Sensor. Installed it and got good Camshaft signal. Im guessing it was updated design.

I feel like this is becoming all too common these days. I mean, it’s just so discouraging. You could have the most diligent diagnostic tech on the job but multiple bad new sensors will throw even the best through loop. It’s just very frustrating, I deal with the same thing. Like I said more and more lately and just what a bummer lol. I don’t really know what else to say about it. But somethings gotta give, I wish there was a way to force these aftermarket companies to provide better parts. Because not only is it a waste of our time, it’s a waste of the customers money.. keep up the good work, brother!

Good catch, Jake! Seems you did have a gap problem. Aftermarket crap ensures you keep buying, in the hope you get lucky (casino like) - pretty expensive "cheap" parts.

[@bradjones2480]

As an engineer that has been down to board level ECM repairs, sir, I admire your skill! Man, I want some of those tools! As I generally tell people, to 'really' fix modern vehicles, you nearly need to be an EE. I don't know your background but you are the kind of guy on the level. I actually stumbled into your channel trying to help someone with a diesel Silverado, no codes, reduced power, and I just sent the guy your vid....lol Easier than having to explain. You have my absolute respect in what you do! You have to be a mechanic/EE/computer programmer, sort of rolled into one to really hammer things down. I really only take on the "dealer can't fix this" cases, but I don't do it for a living like you. I LOVE an electrical challenge but always handicapped with a lack of data. Hell, I don't even have a fun automotive filtered scope like you! Just a decent battery powered 2ch. When time is money, I get it!

[@89gt5.0]

Its a redesigned sensor.nissan did this with the cam and crank sensors. Nissan vehicles do like like after market crank and cam sensors

[@edwinlomonaco6754]

Ivan had one of these that the pcm was bad. And it wouldn't turn on when the pcm was cold.

[@mobilejoe87]

I suspect this will be back again after the battery runs down or it gets colder outside. The PCM actually will communicate cranking on this truck. When it does I recommend just scope a 5vref. If it isn't rock solid during cranking it has failed. You can likely get it to start with 200A boost charge and recreate by leaving the headlamps on. These always come in when it's cold and have the U codes. They will trick you with goofy ckp cmp behavior when this pcm failure occurs. I enjoy your content keep up the good work!

[@autodiagyt]

This was clearly just a dead crank sensor and I've seen a lot of these modules not communicate during crank. The u1000 was history and didn't reset. We the the owner was unplugging things with the key on and set the code.

[@mobilejoe87]

Hey Jake I'm not saying it isn't a bad sensor I'm just saying it has a fault with the pcm as well. I've had several do this. I collect known good scan data including Start-up data on most cars I scan. That vehicle will communicate during cranking. The processor gets an internal Volt drop or something so instead of 10V during cranking it actually see much less. It's easily observed externally watching a 5V circuit. If Nissan diagnostics was a country it would be 3rd world

[@fredautos]

Great lesson, learned jake,. But could that explain why your scanner was loosing engine data pit with the pcm?

[@autodiagyt]

That is an old Nissan thing. All of my scantools even Nissan consult with vi3 doesn’t keep comm when the key changes position.

[@ablackformula]

@11:30, when you were doing your sensor unplugged testing, and verified the signal wire was not shorted to ground, you still had not tested for an open wire to the pcm. While you were applying 12v to the signal wire, a quick glance at the scan tool should've shown some rpm signal. I'm surprised the pcm didn't prime the fuel pump or randomly fire an injector/ingition coil when it saw some (artificial) engine speed. I suppose the magnet test was an alternative way to prove the sensor itself was bad, but seeing the scan tool pid move would've given me more confidence in the call. Either way, great video!

[@autodiagyt]

I wasn’t to worried about the signal wire once I seen one sensor stuck low and one stuck high and no switching out of either that confirmed the sensors was bad if I had of gotten switching out of one of them then yes I would have checked the circuit end to end. With the new sensor I did hear the fuel pump prime but I doubt you can hear it in the video.

[@sohailrabani]

Your notion GARBAGE 🗑 about nissan is spot on..its a nightmare to diagnose it through codes all over system just because of one thing which does not relate to the actual issue..great diag cheers jake😊

[@HouseCallAutoRepair]

A crank code means cam sensor. A cam code means crank sensor... Annoying.

[@DuaneDonaldson]

You should keep records of which vehicles do not have a TACH signal prior to actually starting if you are going to use this info for diagnosis of a CKP, not all cars have a TACH signal at cranking speeds. New vehicles the TACH does not move until the entire Cluster wakes up after the engine starts, some will do a sweep test on engine start and then give a correct TACH signal, cheers.

[@EKHondaMotive]

👏👏👏👏👏 Congrats on your success! How long were you at this diag from start to finish (minus video recording time...I know setup and narration takes a minute)? Cheers.

[@advancedleveldiagnostics]

Great diag, Thanks for sharing! How are you enjoying the TopDon Scope?

[@autodiagyt]

I still don't really know how to use it lol. It's easier to get out and use then the pico. I'm still not sure if it buffers pages or if what's on the screen is all you got. It almost seems the opposite of snap on. What you get on the screen is what you have then you zoom in for detail. It will eat up your scan tool battery if left running. When I get familiar with it I'll do a review video about it.

[@advancedleveldiagnostics]

I was having trouble with my Topdon scan tool on an 07 Nissan as well, same thing.. ## on the live data PIDs. and it was running. When I tried to save the data, those are the symbols I got when I looked at the file afterwards.

[@autodiagyt]

It's a Nissan thing not a scan tool issue. Older Nissan stops all communication when the key position is changed.

[@alanw5879]

Thats what I thought the second I saw those ## symbols on your topdon, and then you explained it. I was all upset I had lost the live data because it was pre-repair I needed for the customer. Nissans are frustrating for sure.@@autodiagyt

[@luiszamora529]

Hello Jake, good job like always, I got question, I got 05 titan and I got PCM code u1000 and no communication with TCM, I checked powers and grounds and everything looks fine,, you think I have bad PCM ???

[@autodiagyt]

I really don't know what to tell you. I've seen older Nissans have modules that talk to each other but don't talk to a scan tool. That TCM is on CAN bus and K line. Nissan isn't something I'm ever confident in when it comes to diagnostics. It seems like the normal for everyone else is the opposite of what they do. I honestly will take diagnosing a Mercedes or bmw over a Nissan any day. They are just not made to diagnose.

[@pushapdeep9662]

Awesome video man. Just one question. The voltage is positive on cam sensor signal and once the vehicle starts, its a square wave. That would make cam sensor pull down or pull up sensor?

[@autodiagyt]

The ECM didn't have a bias voltage so the sensor is pulling it up.

[@mobilejoe87]

I suspect this will be back again after the battery runs down or it gets colder outside. The PCM actually will communicate cranking on this truck. When it does I recommend just scope a 5vref. If it isn't rock solid during cranking it has failed. You can likely get it to start with 200A boost charge and recreate by leaving the headlamps on. These always come in when it's cold and have the U codes. They will trick you with goofy ckp cmp behavior when this pcm failure occurs. I enjoy your content keep up the good work!

[@darkosofkovski6220]

These sensors are active sensors (Hall effect). They must have a power supply to work, they have analog electronics like Schmitt trigger where we get the digital signal. Schmitt trigger has two voltage limits (Hysteresis) such as 2 volts as a lower limit and 8 volts as an upper limit. And depending on the flow of charge carriers which depend on the movement of the magnet can generate a negative or positive voltage. When we have a positive voltage, in that case, the upper limit of the Schmitt trigger will be passed and the output of the sensor will be 12 volts until the lower limit of the Schmitt trigger is passed. Also, the Schmitt trigger is used in these sensors for sharp transitions from 0 to 12 and vice versa, so that switch debouncing does not occur. This means that the sensor can be at both high and low voltage levels and remain at that level as long as schmitt trigger limits are not exceeded.

[@joeandgod1]

This bad aftermarket parts problem has been extremely bad over the past few years. It's been ridiculous.

[@brucelott3583]

To add insult to injury, some customers have been returning parts to the stores for refunds with the used, defective parts in the box. With all the young 'parts professionals' in the stores now, these generally go unnoticed until someone else buys the part. I can't remember how many times I've had to deal with this. Fortunately most of the folks at my parts store know me by name and don't give me a hard time when it happens.

[@jerryplantbasedmonster2129]

what did the cold have to do with it, I bought an aftermarket sensor worked great now at 25 degree weather it will not start?? when it warms up again it starts like a champ, I noticed that the MPG goes -- - - - resets when I crack it and won't start, this other guy took the battery inside the house and let it warm up lol and started the truck, now he said get an 800 CCA battery, I just bought mine and the truck calls for a 700 CCA and that's what I got I also saw the intelligent distribution panel (I think that's what is called) get swapped from the white one to the upgraded black one, I already have a black one I believe they say it is the relay to the ECM that will not work when it is cold something about the resin melting in it, but hope this helps someone, I bought a new relay I hope that fixes my problem. the last time it did this I tried replacing the relay but the cover from the relay broke in pieces when I was pulling it out so I left it in, I went in and I cranked it right after that and it started first try and have not had an issue until this morning at 25 degrees, IDK I got the relay now hope that is the bad part. Hope this helps someone.

[@autodiagyt]

Just pulled it out and put it back. It has a rubber o-ring on it and I might have not gotten it seated completely flat the first time. It was hard to push in the first time and when I pulled it out and pushed it back in it went a lot easier so I’m guessing the dry o-ring was keeping it pushed back some.

I’m in a small rural town with a median income of 25k. My labor rate is higher than every shop and dealership in my area, but as an industry average I’m on the low side of the scale.
