Angry GMC: Runs Like GARBAGE! (Stall-Misfire: P0336-CKP Performance) 

One thing you know for sure: If the customer has a big grin on their face you know you did something right.

That thing isn't angry, that's a super spicy GMC.

I'm becoming a fan of your NPR repairs, nice diagnosis (again).

Nice to hear the Chevy Thunder....oops not Eric O...love the picture of the Yellow C6 have one sitting in the garage, 448HP 6.2 LS3. Love the Diagnosis could not have seen the clue without the scope and a visual on the sensor, nice.

Wow! So much depends on such a small detail! That would be so easy to miss!

Ivan, thanks for including the PICO waveforms. I don't know how many times you said you doubted it was a gap issue, but several. In the end it was a gap issue which leads us to concluded you must keep an open mind, be very methodical in your approach, and be prepared for the unexpected. And....you looked like you were having a great time on the test drive. Thanks for Sharing!

That's one smart owner. He knew the exact person to call about his problem.

I remember that hole in the crankcase video!

I recently retired from truck driving but I used to work on cars a lot before sensors,so in my retirement I’ve decided to educate myself about such things and you’re the best to watch it’s not for everybody but it’s just what I need because most people are frightened to death of cars these day’s,I’m in the uk and if it’s any consolation it’s snowing here as well😂P.S I watched one the other day and your wife was in it you’re a lucky man she’s beautiful

Ivan, thanks for the video! I really enjoy your work!

ANOTHER great diagnosis! Good job Ivan!

Great diagnostic, Ivan! Second time I've seen you fight a sensor gap with NPR results. That truck is a mean beast :-)

Wow. Your ability to process "long" and "short" pulses is better than some of my violin students 🤣

It's awesome that the Saudi students are enjoying those trucks!

Smiling customer, no parts required. Well done,Ivan

Starting this video I heard in m y head, "please please please solve this one in this video without going to part 2" . Thank you for that small favor ;-) (and yeah, these make you think, and they are fun)

Oh that shortbox stepside in the background ❤ I’m glad mine has a 4.3 V6 as the crk sensor lives out front on the timing cover, easy to get at

Watching you work under the truck with snow on the ground made me turn my heat up. Great job.

You can see the happiness on the face of owner of the truck.he got his holidays present by ivan his truck fixed and no extra cost.stay safe ivan its too cold and happy holidays.enjoy some quality time with family and friends.cheers

Fantastic fix. Learned a lot on this one. Merry Christmas.

Good diagnostics, good times! Thanks Ivan!

Nice fix ivan. No parts required . Merry Christmas to you and your family. From ENGLAND.

Great diag and repair Ivan.

Another fine "NPR" diagnosis and repair. Keep them coming.

Seems like this same issue popped up on south main auto as well. Power of a visual and paying attention. Could really go down a rabbit hole on this if you don't keep a level head. Good one. Thanks for the ride along.

Nice job Ivan!

As always, Ivan, well done!

Well done Ivan. I had a Range Rover Evoque with a cam crank code and the crank sensor had a similar issue in detecting the teeth at higher rpm. Distance matters, especially with cheaper oem parts that aren’t as sensitive to begin with. All hail King Ivan, Lord of the NPR repair.

Great bonus footage and test drive😀

Strange reluctor wheel set up!

Let's see an electric truck sound like that! Not! Nice work Ivan.

I love to watch Ivan videos than other video out there I’m not saying that they are not good but because there’s no shortcuts it’s like your watching a good movie… it’s amazing

Well done ivan 😀 It's such a crude sensor fit for a critical measurement. So the amplitude of the pulses may not have been high enough to register on the input of the computer all the time. They should of put two bolts on a ring to apply pressure to both sides of the sensor. Tight ass manufacturers lol. The owner looked so happy 😀

Excellent job Ivan.

Job well done @Pine Hollow!

Kewl repair. You are a pro.

Did you ever verify if that sensor that was in it was OEM??? So you never tried the old part man took out for comparison sake??? Amazing Ivan. What a clever diagnosis and results

Wow, that is one angry GMC lol. Never heard of 5.3 getting that mad lol. I've owned many 5.3s and I'm really surprised by that air gap with the ckp sensor! It's not usually common issue. Unless it has chain stretch which is common thing! But go glad you got it sorted! Awesome video!!! Many thumbs up 👍 👌 👏 But you mentioned At the end it's 6.0? 😄 what gives lol

Ivan saves the day again!

Excellent job.

I have the same energizer headlamp. Mine is over 15 yo still works great!

Once again "no parts required"! 👍Now if I could get some of your video magic to rub off! 😆

Another genius diagnostic.

Lol smart kid not letting Ivan drive atleast he knows that Ivan would have left a little bit of tire on the road 😂😂😂

Nice diag. That truck also sounded amazing.

Yay! What a fun truck!! Another NPR Ivan!!

I love Alabama don't see much of those problems great job

Nice job Ivan. That truck is pulling booty there at the end. I bet he was damn 😊 happy!

I've seen this a couple times. Happens on dodge magnums too. Rust builds up right by the o ring and just that little bit will cause problems. And I'm not sure Ivan, people on the internet tell me all the time that I don't need a scope. "Just use a dvom and watch for voltage changes" makes me wanna beat someone lol

Great video! It sure does sound bad-ass!!

You are awesome, thank you

For whatever its worth, I worked for the Saudi Army in the Kingdom as a mechanic/trainer from 1992-1995. They pronounced "G-M-C" as " jimss". Find enclosed two cents.

Nice truck, belongs way out in the country. Away from folks who appreciate quiet. But another great diagnosis.

Good video. I would have suggested showing waveform post clean up.

Nice job, truck sounds good to

Saudi student community 😂 Ivan is making bucks out of MBS

Nice video Ivan!!!

haha the bonus footage in car with the owner. he was loving it

Sounds dope

You are the man❤

That rust sure causes a lot of problems! The owner's REAL HAPPY now! How long did the truck sit before you got to it? Hopefully the gas tank was full so no moisture collected in the tank. This diagnose reminded me of that GM pick up with OBD1 when you swapped PROM's in the PCM. With all the mods done to it, it's a wonder it runs. Maybe a good dyno tech could help it run better for optimum performance. Good fix Ivan!

Nice fix! But the car, jeez, this must be one of the states where you're not required to have a muffler, I'm glad this is not allowed where I live.

That 80psi oil pressure daaaaamn. I wish my ls1 had that kind of pressure

well, Ivan is now more familiar with LS engines and the goofy two piece riveted together and interference press fit onto crank with no key/dowel pins! :) not that you will, but to install/remove them you heat the snot out of them and work carefully, precisely marking alignment is critical before removing them or make/buy a special alignment jig.

Crazy, crazy reluctor wheel setup. Where did the second one come from ? Fast diagnosis on what could have been a very tricky problem. Another customer who'll have a happy Xmas on "route 66".

Nice going

The ending was fun!

Buick 3800's of most era's use two tone rings on the back of the harmonic balancer and two Crank positions sensors (it is one physical unit, two hall effect sensors). One tone wheel is evenly spaced, same size teeth while the other is long and short to indicate cylinder TDC. Even the GM sensors for these are now junk so a better bet is anything with lifetime warranty and being skilled at swapping them.

Daaammmnnn! That thing gotta a cam in it! Lol.

I have a 2000 Silverado 6 cyl that sounded the same last year. I was reyving it right after I got it to start and my muffler blew up. MAN! Leaves were actually falling out of the trees! I got out and the two drain plugs in the bed had cleared and were draining water that had collected in the bed. I was seeing people peeking out of their curtains to see if maybe they should get under a sturdy table. It was hilarious! By the way, mine was the distributor. You should have seen the muffler.

GREAT VIDEO

That truck sounds nice though :)

The crank sensor magnetic surface position to the teeth is very precise, I guess it should be parallel to the teeths, and the bracket play a big role in it, if the bracket somehow deformed, it will definitely affect the performance of the whole sensor, and as consequence bad engine performance.

Sounded like you were reading out rally pace notes all those shorts and longs 😂

good solution, it was not expected, if you have 12 p codes, where do you start, it runs fine for a few minutes cold

he seems like a good dude!

wow pretty Different reluctor wheel notches..i'm learning every time something about car engine ins and outs. 6L beast, not sure i could afford the juice to run it at current prices in OZ..LOL

The ability of the standard ecu to have the scope to deal with that cam and banging exhaust is quite impressive really.

The sensor is sensing the complementary target. It senses the shift of the magnetic field from oneside of the target to the other. This design allows for less sensitivity to the airgap. Also allows zero speed detection of target with high tooth count. Same type of sensor for the cam shaft but its target is machined. Not a sandwich stamped target like the crank shaft target.

Thumbs up for you Ivan, nice work! BUT thumbs down for that truck.. let us know when the engine blows..

Back in my tech days late 70's. I worked in a small college town. All the Saudi's loved the trans am smoky and the bandit. Trucks now!?

Am I the only one who does the intro like Erik O. It’s a 2000 CHEVROLETTT. It’s got the big 5-3. It’s got the heads. It’s got the cam. It’s got the exhaust. But it’s got a little hitch in it’s gitty up.

Thanks

exselentes master god amigo

Fixed the rumbler V8 that is 22 years old. food work.

Live for the CHOP CHOP

That was a good one

could be magnetic inductance from a magnetized relutctor wheel... stick a neodymium magnet on a stick into the crankshaft position sensor hole and turn over the motor with the starter several revolutions...

Sounds like a race engine at first, 😆 Edit: so it's heavily modded, sweet! Love the group of car guys at the apartment block!

Ivan, you are crazy working outside in that weather. 😂

I've actually heard a motor sound like that before ... mind you, it was a 16cyl locomotive engine, and it was 34f so only about half the cylinders were firing when we finally got it to keep running ...

Thank goodness it wasn't an improperly routed ground strap and magnetized crankshaft 😉.

Cool

He needs that pool of water in the cover for the weight to improve traction! Lol!! Jeepas !!

You're something else.

here's is someone watching you from Saudi lol

I have 369k miles on that GM best vehicle s I got 400k out of 5.3 GM one transmission Cam loping with rich exhaust throw a O2 fuel trim code? Aftermarket parts often POS. CAm and Crank sensors compare to check timing chain stretch or loose cam gear reluctor. I found metal chips on sensor magnets also cause havoc.

I wonder if the old sensor was rust jacked out of place tossing the code. Replacing the sensor didn't work because of failure to clean up the hole before installation. Huh. May never know.

Oh I've seen those that's one of GM's new three-cylinder models

@Pine Hollow Auto Diagnostics Hi Ivan. Thank you for the great content. Can I use a picoscope 2204a or 2205a for this type of diagnosis?
