Okay, well, I just checked and found that yes, I did break one of the 3 wires off from the crankshaft position sensor connector, which is why the truck won't fire. So I either need to splice in a new connector with a length of all three wires or get a connector tool and try to fix it. Edit: Didn't plan on fixing it tonight, but the local auto parts store had the part, so I went and got it, spliced in the new connector/pigtail and the truck runs!
Nice work! Thanks for watching!
When doing this to my 2001 Suburban 5.3l,
I had to take the 15mm bolt out of the dipstick tube bracket (from the top side) and pull the dipstick and tube up and out of the way so the starter could then be pushed back. My starter had no room to slide back until I did this. Hope this helps.
Hoping they fixed this on the 2002 models, not looking forward to this fix
Can it relearn on its own? Or must we do what you did here?
You can get to it by going through the RF wheel well; just remove the wheel and wheel-well lining. Also, I'd disconnect the battery before messing with the starter.
I think that was the very first thing he said when he started explaining the process. Paying attention pays off bud.
There are a lot of cheaper scanners that can perform the crank position relearn. I really like the Xtool D7 because the cost to capability is excellent.
Tip... don't use oil or grease on rubber seals. Solution, use silicone paste with teflon, it won't swell the seals or make them soft like oil and grease.
Good tip! But most people have engine oil and I want to make these as accessible as possible. Thank you so much for watching!
wouldn't wanna get engine oil on an oring that is used to keep engine oil sealed in.
This is pretty much how it goes. But I'm sure 99% of us don't have a car lift in our driveway or garage. So you'll be doing this on your back in the ninety-degree heat trying to finagle that sensor out without smashing into pieces mine was stuck in there pretty good.
So do you want me to not use a lift? I'm confused. Thanks for watching!
@@2carpros that’s not what he was saying at all. Lol.
Do I need to do the relearn process?
That shirt is sweet. I've known that firing order since I was old enough to know anything.
I love that shirt I got it from David Frieburger's website and I always get people asking me about it. Thanks for watching!

Always good videos. I agree about using oem sensors especially when it's fiddly to get to them.
Yeah definitely! Thanks for watching!
After i replace the camshaft position sensor then this Thank you 🙏🏻
Wd40 makes a silicon lube in a can now and works great for o-rings
Got to get me some! Thanks for watching Charles!
Great video.
If I just want to replace the O ring and not the sensor. Do I I still need to relearn with system. Since I’ll be unplugging it.
I think if you replace it with the same sensor it will be ok. Thanks for watching!
Do you always have to do a relearn, if it still doesn’t start could it be because of the relearn❓ thanks
No. I just did mine. It will run but it will be hard to start. There is relearn that you can do without a scanner that helped me. 55 mph for 2 min drop to 45 for 1 min using no brake. Then 4 more times from 55 to. 45 using no break. Google it if you don't have a scanner. But you need 15 miles of straight road . Good luck
Hi there, thanks for the video but where the location of crankshaft sensor because in my truck Duramax 3500 2005 6.6 diesel it's not behind the starter so do you have any advice thanks
Went to a local shop for a diagnosis. And we were talking about this. But we were tryna figure out why 7 and 8 were misfiring and fuel injectors didn’t look like a problem changed coils wires and spark plugs still misfires when I floor it at high Rpms. I don’t know if I fix this it’ll work but I’ll try it out
Great video, but I think why they had locate this sensors in a soo freaking tide locations
How different is this on a Chevy 4x4? I heard the oil dipstick tube is in the way from underneath....maybe there's a better method on the 4×4s?
I don't see how it would be different. There just might be an axle in the way. Thanks for watching!
Through the wheel well
Hell of a good video 😂
Thanks for the video! I'm going to attempt this on my 09 Hybrid 6.0L. I'll comment back when it's done and hopefully won't have to do the Relearn.
Edit: the starter is in a different spot so I easily did this with a 10mm and elbow grease! My CEL is still on even after a reset from my scanner so either I need to relearn it or unhook the battery for a few...
If this fails will it act like VATS?
It will most likely stall or not start. Thanks for watching!
i just bought 04 gmc Yukon 6.0 77k miles when i am at stop it cuts off rpm drops low, previous owner changed the fuel pump, throttle body no check light.
When these go bad, can they cause the dash tach to drop off on the freeway or under moderate load (acceleration). I'm fiddling with a P0342 code, and my tach will drop off when on the freeway or right after moderate acceleration up hill.. I have a 02 LS1 in an F-body. No sure if I should go after the Cam position sensor first or do the crank position sensor (it looks so much easier than the Cam Sensor)
What usually happens when these go bad, is a crank no start or an intermittent stalling problem. I would swap out the Cam sensor and see if that fixes your problem. Thanks for watching!
I just replaced mine and it started without any issues. Do I still have to have it relearned?
Mine stalled twice last week and I was able to bring it home just by removing the ground cable.
How far can you drive? it to get it relearned
It should drive if that was the problem no matter what. We drove ours 35 miles or so before the check engine light came out asking for a relearn. Any shop should be able to do a relearn in 5 minutes for very cheap. Or you can buy an expensive scanner and do it yourself. Thanks for watching!
I ODB reads P0336 I changed the sensor and it still doing the same thing not starting but I keep getting the same code. Could there be any other problem?
I've always wondered the reason for disconnecting the neg. battery cable, rather than either one cable?
You need a light disperser so people can see better, other than that your doing great
Thanks for watching James! This was a pretty tight shoot due to the location of the sensor we usually have decent ligthing.
Is the wire going to the crankshaft position sensor connected to the starter wire harness? Does the wire underneath the starter on the left side go up to it? I wonder if I pulled too hard and disconnected it or pulled a wire out. The truck won't fire now, but did before the starter replacement. It's the only logical explanation for it magically not firing after the starter job.
Did you ever get this fixed I'm pretty sure I'm dealing with the same problem rn it was firing before the starter job and now the new starter went it and now not firing at all
Great info sharing! Thanks, I'll be doing this tomorrow or next day.
Would the crankshaft position sensor cause your tachometer gauge to read too high?
I don't think so. The gauge itself is most likely having the problem. Thanks for watching!
Why do you have to disconect the batteries
You probably don't need to but the idea is to not freak out the computer. Thanks for watching!
Man i changed my starter on a 2003 GMC 1500 and now its cranking but no spark??? Im puzzled because truck was running fine before i changed the starter?? Any help? Not getting spark now????
Maybe you accidently unplugged the CPS when you changed the starter? Thanks for watching!
Does the 4.3 Astro van also need a relearn? Thanks
I'veI done many crankshaft sensors and have never seen it stated in the instructions to lube the sensor with wheel bearing grease or oil of any type. Usually there are no instructions that come with the part. Just replaced one on a couple of days ago where a so called ASE mechanic didn't even check for clearance and just push the sensor in place smashing it up against the innards, causing a huge gouge and scratching the sensor up badly. The one was a mechanic in name only.
He's putting grease on the o-ring so it doesn't cut it when inserting it. You don't want to put any o-ring in dry.
What do you know about the different teeth on the reluctor on the crank, and getting the right while replacing the engine, not sure how many different ones on a 5.3 Ls 1
It is matched to the year of the truck. I believe only the smaller amount of teeth came on these older trucks. Thanks for watching!
when i phoned my local parts store they asked if it had right or left tab ?? not sure what they mean by that . she didnt know either . the pictures all look the same
What? There is only one crankshaft position sensor. Never heard of left or right tab before. Sounds like they didn't know what were doing. Thanks for watching!
Would it be the same procedure for a hummer H2?
Yep. Thanks for watching!

Can I drive my truck to the shop to have the relearn thing happen or will it not work
Ours worked after I put the crank sensor in. Didn't even have a check engine light until later, then I could relearn it with a fancy scanner. So yes you can drive it to a shop for a relearn. Thanks for watching!
would I need to drain the oil before taking out the old sensor?
Nope. Thanks for watching Daniel!
Its not easy, I broke mine off in the block and took me 3 hours to fish it out. Still didn't fix my problem and still shows the same code. I had to take wheel well out to make it easy.
Are these things known to leak oil on the starter?
Not that I know of. The starter bolt holes are blind so they can't leak oil. The only thing that can cause that is a oil pan gasket leak and its whipping up onto the starter. Thanks for watching!
Hi, I have a 07 Tahoe 5.3.
I got p0300 code random misfire.
Changed coils,plugs,sparkplugs.
And is still misfiring (hesitates)p0300.
What are the chances that I have a bad KPS based on your knowledge?
I just can't get my head around it.
Car was running fine before.
@Daniel_el I have the same issue starting to believe its my crankshaft sensor!!! Gonna install one tomorrow
@@TexasRigour
Let me know how it goes.
Cause I changed my camshaft and crankshaft sensors and MAF sensor too. And it still misfires.
@@dannysa503 what’s your spark plug gap at
@@dannysa503 I changed my PCV valve that helped a lot also changed my idle and engine light stopped blinking (update it’s your fuel injector) motor threw bearing out had to swap it
@@TexasRigour
Sparkplugs are at 40.
I also changed injectors.
What are the symptoms when this is bad ?
Intermittent stalling and not starting. Thanks for watching!
@@2carpros thanks
My truck Silverado stalls randomly and no mechanic can figure it out. Will this do the fix. I already replaced the fuel pump.
It stalls at any speed at anytime. Truck don’t have to be warm for it to stall.
Will this fix my problem?? Thanks.
Yeah I would change this 100 percent and then maybe a camshaft position sensor. Thanks for watching!
@@2carpros what will happen if i dont re learn it? will i still be able to start and run the engine safety? just so i can get to to the mechanics?
@@joehill647 Yeah it will start, it will just throw a code until your get it re learned.

If you don’t have a check engine light, can you skip the relearn? Wouldn’t the ECU simply relearn over time? Thanks.
It will most likely run for a little bit until the monitor resets, about 35 miles, and then the check engine light will come on. But the truck will still run, you just have to have it relearn after that to get the light off. Thanks for watching!
Reply might not have worked due to the link, I added, but here’s a “relearn without a scanner” procedure option. See any issues with using something like this?
“How do you relearn a crankshaft sensor without a scanner?
- Turn off all of the accessories.
Accelerate the vehicle to 55 mph at part throttle.
- Cruise at 55 mph for another 5-6 minutes.
- Decelerate to 45 mph without using the brakes, and maintain 45 mph for 1 minute.
- Perform 4 deceleration cycles, without using the brakes, of 25 seconds each where no specific speed is necessary.”
The second version reads like this, but it looks to be basically the same “relearn without a scanner” option:
“NOTE: If the Crankshaft Variation Relearn is not accessible through your scanner (some truck applications 1998 & later), perform the relearn in the following manner:
1. Turn off all of the accessories. With the Air temperature sensor and Coolant temperature within 5 degrees (Centigrade) of each other, start the engine and let it idle in Park or Neutral for two minutes.
2. Accelerate the vehicle to 55 mph at part throttle. Cruise at 55 mph for 8- 10 minutes until the engine reaches operating temperature.
3. Cruise at 55 mph for another 5-6 minutes.
4. Decelerate to 45 mph without using the brakes, and maintain 45 mph for 1 minute.
5. Perform 4 deceleration cycles, without using the brakes, of 25 seconds each where no specific speed is necessary. Returning to 45 mph for 15 seconds in between deceleration cycles.
6. Accelerate to 55 mph and cruise for 2 minutes.
7. Stop the vehicle and idle for 2 minutes with the brake applied and the transmission in Drive (automatic trans.) or Neutral (manual trans.) with the clutch depressed.”
So I did the “relearn without a scanner” procedure, and so far no check engine lights. The truck seems to be running as expected. Hopefully, it took.
@@shrouts777 Are you still good? How is it running?
Can the oring go bad and cause oil leak from sensor?
Yeah sure can. Thanks for watching!
@@2carpros Ok i got oil leak coming from up top behind intake i felt it was wet around that sensor its running down to the starter im going to change it out tomorrow
I've replaced my crankshaft sensor and the o ring twice in the new one and it still leaks oil, what should I do differently?
Why didnt you put dielectric grease in that?
On the sensor itself? Because it gets bathed in engine oil. Or on the connector? Because it has a weather pack built right in. Thanks for watching!
Wil this cause reduce engine power
No, not at all. Thanks for watching!

Thank you! If you like the shirt make sure to check out our entire build series on the legendary Big Block Chevy 454. Thanks for watching!
Question: so after i installed the crank position sensor i can drive it to a shop and have them program it?
Yes you can. Thanks for watching!
How much did they charge for the learning?
Could a bad sensor also point towards stalling while decelerating?
Yep. Thanks for watching!
It sure can..my 2010 Yukon 6.0 did...but once u replace it..u all good😅
Question, would this solve a p0343 code on a 04 tahoe 5.3? I already replaced pigtail and camshaft sensor, but still getting this code.
I had this code after I replaced the camshaft sensor, turns out I either had a bad sensor(aftermarket) or i didn't put the sensor all the way down. I replaced it with a ac Delco part and re did the wiring harness and made sure it was all the way down and that code disappeared and never came back.
@@CLASHWITHTRILL thanks. I figured it out. I crossed wires when I installed the new one. so I rewired it and now I got no issues.
Thanks for the video👍👍👍👍👍👍👍
Thank you so much for watching Salvador!
was this a crank no start situation?
Yep. Thanks for watching!
Nice job
Thank you! Cheers!
Just wanted to make sure every crank sensor has that O-ring or some kind of gasket since my Suzuki's missing it and leaks oil crazy
Yeah it has to have some sort of seal or it will leak like a sieve. Thanks for watching!
is it just me, or does that bell housing look cracked... or is that just quality GM casting?
Could just be a casting seem. Or its a crack, the truck is fairly old. Thanks for watching!

Will this cause you to fail emissions?
Yeah if it is throwing a code and therefor a check engine light. It will fail smog. Thanks for watching!
Why would you want to change it? What’s the code?
We changed this because the truck wouldn't start and was throwing a P0335 code. Thanks for watching!
Thank you!!!!
You're welcome!
It will not affect anything if you put the crank position sensor and Driver to local shop
Correct. Thanks for watching Gustavo!
@@2carpros tanks 👉☝👍
How do you know it was bad
It throws a code saying it's bad, also it had intermittent stalling. Thanks for watching!
Will this sensor cause a misfire and hesitation under load? Truck runs good at idle but if I hit the gas fast it backfires through the tbi and trying to drive it does also.
That sounds more like a spark issue. Thanks for watching!
I have the same issue did you ever figure it out?
How much is it to have a mechanic replace and do a relearn?
Replacement and relearn? Something like $140 or so. Thanks for watching!
The cheapest quote I got for the replacement and relearn is $275 and the most expensive quote was $395.
