Ram 1500 is setting a Cam Sensor Code because of WHAT?!?! 

Great diag! The power of the scope, knowing what youre looking at & a solid diagnostic process!

Jake, I like the fact that once the scope gets attached all guessing goes away and you can actually see what is going on. It also helps that the scope is in the hands of a talented user. Appreciate you taking us through the process step by step. Thanks for Sharing!

Awesome diag Jake. I remember once I diag'd an older ford van the customer believed had a bad transmission . Vehicle would shift erratically, banging into gear, etc. I checked the powers/grounds to the trans module in the trans. Couldn't find any problem. Almost called a bad trans module but decided to test drive one more time. Noticed a slight intermittent misfire, that's when I suspected I had RFI interfering with the trans module. Sure enough, replaced coils and problem was gone. Crazy! Great approach to finding your problem. Thanks again for sharing this and thanks for what you do!

A coil primary current ramp and a secondary KV analysis may had show the reason of the spike. Great diagnostic. Very logic approach.

Great video man loved every second of it!

Brilliant diagnosis and scope work! Thanks for sharing.

awesome diag and video Jake , what a beautiful day there, keep up the good work , love all your videos

I get a lot of Ford Fiesta and Focus with charging faults - usually they come in with new alternators that haven't fixed the problem. The TI-VCT (Sigma) engines run a waste spark system with coil pack on the #4 end of the head and 4 leads. One of the leads breaks down internally at the coil pack end and there's enough energy in the system to jump the gap and not have a misfire under load - but it radiates massive electromagnetic fields and corrupts the LIN signal. On one particular version of the 1.6 the LIN wire is high up by the head and even more susceptible to ignition interference. For cars equipped with them, usually sets an active grille shutter fault too (same LIN bus) Generally find one of the coil towers full of blue dust, but either way, simple resistance check of the leads proves it needs a set. Aftermarket are never the correct length, so go genuine. The baffled look on the tech from the other shop when you tell them it needs a set of ignition leads to fix the charging fault :D

Excellent lesson . Thanks for all your hard work teaching us.

Great diag! Imagine figuring this out without a scope. Impossible. Great case study and this will definitely be stored in the memory bank. Keep up the good work!

Hello Jake, Your videos are always extremely well done but this one is a couple of notches higher. Superb job!

Mine had and same code, and did this days ago and multiple times a day as it went into limp mode aka 4th gear lock with traction control light on. My solution. Adding engine oil cause mine was low (2+ quarts). I know I didn’t believe it either but it solved mine. Try easy stuff first. You’re welcome!

Jake terrific video and awesome scope troubleshooting. Very informative. 👍 Artie

Those were some sweet scope captures Jake! Autolites are the worst plugs ever made 😂😝

That was an awesome diagnostics! The scope is definitely a powerful tool but only as good as the man who is using it! You are the man!

learning something new every day, great video

Excellent diag Jake! I like that you use Pico 7

This is a perfect example of why having a lab scope in your arsenal is so important. I still use my DMM for your common stuff but when it comes to sensors and data the scope is my go to.

My dude! Diag is my Jam. Over 24 years in the Diesel/Auto/Everything. Your video is damn near ASMR. Thanks for the content.

Your information is easier to follow because of the screen overlay and the inserts thanks.

Very convinced on getting a scope thank you for the informative video 👍🏼👍🏼👍🏼👍🏼👍🏼

Excellent diag! Really well explained. Without a good oscilloscope this one would have been a parts canon! A lot to learn as always! thank you for sharing!

Excellent diag took some real know how for that diag.thanks for sharing Jake.

Nice diag, when I saw the Autolite plug, I was about to say exactly what you said!

Watching you do this felt like my real life shop life😂 Seriously, I have been there and done this, comrade! Only thing I would have done different is I would have used the amp clamp for my coil sync (not cause it’s better; just cuz it’s easy, but also because I would have been interested to ultimately move it to the bad one, being curious about the kinda current it was pulling (might have suggested shorting coil vs secondary issue at the cause). Great video though Jake! The people need to see this stuff to know what’s happening in real troubleshooting shops!

Brilliant diagnosis!

The only scope I have is in a snap on scanner,. I see why you really need a Pico, thanks you for these very useful videos.

very swift accurate data led diag. very nice 👍👍

Thanks Jake for the valuable lesson, appreciate your videos :)

that is thinking outside the box. good job.

Awesome video and diagnosis. Trying to figure that one out without the scope would be tough. That would take a lot of reloading on the parts cannon. 😂😂

As always a awesome video and the best part of it I always learn with your videos and especially how to use osiloscope …facts

Great informative video as always.

excellent diagnostic

I’m having this same issue for almost a year now and it makes sense now. I was tempted to buy a new PCM but now I’m gonna try this. Thank you.

Thank you for your time

So, guys, I have been having this issue for over a week now. I changed the cam and crank position sensors on my 04 Durango 5.7 and the problem persist. So I kept feeling kicks in the engine while driving when the light was out. I figured out that my engine was misfiring due to a faulty ignition coil. This code must be a fantom code that comes on BEFORE the coil fully gives out. So I replaced all 8 coils and my D-rango is running like a top. Thanks for the video.

Nice find. Great job!

Interesting video! Excellent content. 👍

Great find there Jake 🤘🏼 one day when I grow up I wanna be just like you 😄

Excellent find

Jake, going to be honest I have not watched the video yet, wanted this comment to reflect what I thought of when I read the title. I’m working on a Kia optima right now, crank, no start. with a crank sensor code. That will just keep on coming back. My DIY customer through so many parts of this thing. It’s unbelievable, including a high-pressure fuel pump, earth cam sensors, the crank sensor to name a few. Just figured out yesterday that if I unplug the high-pressure fuel pump, it starts… Going to finish my Diag tomorrow, but just wanted to say your title. reminds me of that in this video! Anyways, man gonna watch the rest of the video now! Rock on, I have learned a lot from you you’re a bad ass! Thanks!

I have the Pico 2204 because it was inexpensive but the 4425 is on my wish list. I also just ordered a one channel scope for less than $100 hoping I can use it for some quick testing with the idea scope data would be more useful than what you can read with a DVOM. Reading sensor signals, network activity, and the like to determine a direction then use a better scope for the final diagnostic testing. That's the plan at least.

Great video and info thank you.

What an interesting presentation for a bad plug connection. Presumably the bad contact led to higher secondary voltage which was picked up at the 5V reference by induction. I guess it didn't misfire because it wasn't necessarily shorted to ground

Great job buddy keep up the good work my friend nice video

PICO #1 scope with deep measure works great. You can run the picked fence and it will show each drop out, can set threshold also with other measurement setups. Personally a snapon scope is 10 yrs behind our time for the dollar. Good video content 👍

very cool find, thanks for this vid

awesome stuff. I just had same truck and only difference I cant get it to set code again to catch it like you did.

Great thought process leading to a solid diagnostic, Jake! Pretty weird fault, though. That sensor ground seems a bit too noisy, but maybe it's just the way it is. Yep, only a scope can get these.

Nice work! Thanks!!

Wow brilliant case study, Thanks! This would be a good place to use the escan elite with the escope I think it can stop the scope when the code sets. I just cant justify the investment when I'm really happy with my Pico.

God catch man !

Well done 👍

Nice one man!

Nice work bro

Crank shaft sensor but more what the sensor reads ,: attached to the flexpyknown as the " reluctor ring " has a magnetic strip that falls apart, to access it is to remov the trans, may as well perform other maintenance torque converter, flexplate swap new cost $65. ( Thinking only the sensor on the outside is bad, is verified by checking if it works with a 9 volt battery

Hero...

Great job I'm not sure if my Snap-on would have seen that

Good job bro

Dam good job.

nice job!

Exellent...!!! 👌

good one tks

I have seen before on a Ford Ranger. It sets an O2 sensor code but the waveform capture says otherwise. If we didn't use the Snapon our scope would have been fried.

Very nice

Brilliant diag Jake, well done. How did you know it was a coil doing this?

hi ... I'm from Iraq I'm very interesting in your channel and I'm learn from this Troubleshooting good job thank you ..... one question plz can you advise me for best test tools from amazon such as test leads/back probes/ piercing tool / multimeter /dc clamp meter etc. any thing you see helpful in this field plz I'm just a beginner ( one year car technician Jeep /Dodge /Ram ) ...... sorry if my English not good but i understand you very good especially your Sierra Injector Fault video 💪💪💪

Mine was due to a bad VVT sprocket. Mechanic scoped both the camshaft and crankshaft position sensor and found nothing wrong until he took out the cam position sensor, stuck a screwdriver inside the sensor opening, and found the sprocket vvt cover was loose causing the intermittent signal.

Makes me curious if it could possibly be the PCM ground that is intermittent. It would probably throw more codes though.

IF im not mistaken I believe most mopar coils have black boots so that one you have there might be aftermarket. I definetley want a scope now...havent had much problem vehicles but on this one I probably would have had a hard time without the scope. It looks like the 4425a is the one to go with? Is it best to just buy the starter kit or just buy the actual pico on its own and add as I go? Also what's the best way to accumulate test leads? Buy pieces/parts and make my own or just buy a ton for the pico? Thank you for the help VERY much appreciated.

For curiosity's sake, I would be interested in seeing if a Faraday bag tied around the CMP Sensor might give a hint that the source of interference is from radiation of an external electromagnetic source. In this case it was but I would like to see if the Faraday Bag idea would help in the troubleshooting approach. ??

❤❤❤

i service a fleet of hemis have seen the boots be like that when i forget to put dielectric grease on them and you cannot use any plug but what comes in them if you want them to run correctly. have tried several times and always have to go back oem in fact i get all of them from mopar

That was awesome!!! 2 questions, 1. The Attenuator, that's a new one to me. When would I employ one? 2. What was the tell tale thought that brought you to check a coil?

Great video man. Quick question for you, why do you have to use an attenuator? How can one know when it would be needed? Only 2 wire systems?

Unfortunately he didn’t replace the coils and prove out his diagnosis by the problem being resolved as more driving may have revealed the code again with new coils as well. That was a lot of noise on the 5v and 0v. Seems like there may also have been a ground problem.

It looked like the ground is picking amp ramps of the coils?

👍👍

I had a P0345 code set when I overfilled the fuel tank on a 2018 Grand Caravan......??? Happened twice!

👌

Could that be a pinhole in the coil?? Arcing?

Do you have a fix video

What model picoscope are you using?

8:04 why directly jumping to the sure conclusion that its coils doing this ? nothing else can possibly cause it too ?

Hey Jake question for you. What made you go to the coil once you saw a spike on the cam sensor?

Hey sir,,, How test primary ignition voltage 3 wire 4 wire cop coil

Nevermind. When you zoomed in it didn't look anything like amp ramps.

QUICK-WITTED Automotive Diagnostics & Programming 👍 From Nick Ayivor from London England UK 🇬🇧 ⏰️ 08:28am

21:07 is Topdon able to update the Code so fast Like the snap on?

Will a snap on lab scope be able to pick that up as well or do you need a pico scope

i need scope

How did you count out each cylinder on the scope to find out #6 was the problem?

THANK YOU FOR THE VIDEO ,,, HOW DID YOU IDENTIFY NUMBER SIX CYLINDER . I SEE YOU USED NUMBER ONE CYLINDER AS YOUR SYNC,,,,,,,,, AND WHERE YOU USING THE SPIKES IN THE CAM NEGATIVE SIGNAL AS THE ENGINES FIRING ORDER . ADVANCED TECHNIQUES FOR SURE THANKS AGAIN ?????????????????????????????????????????????????????????????????????????????????????

Hey sir how are you

is that a 10:1 or 20:1 attenuator???

I have a cam issue with my GM 5.3 i scoped it but can’t figure why I only have wave from 0 to 3 volts?

How did u know the ground wasn’t dropping out? I would have got smoked on that one!!

Autolite plugs re not even worth the box they are put in. Garbage that advance sells millions of em based on p0300
