Best video so far. A good picture is worth a thousand words. Thank you sir!
Glad you liked it!
Thanks for the detailed video! I used it for reference while replacing my '03 Tahoe. I didn't have a oil pressure sensor socket, so I used a 1-1/16 deep socket. Also, the last tip about using your cell phone to video and take pics of the oil pressure sensor area helped me find it in the beginning and end when installing it. It also helped me see if I had a filter. Luckily, I didn't have one which was a plus.
Seeing other videos showing them taking the manifold off was so unnecessary and added steps you don't need to do. I guess if you have gigantic hands, you would have to take this route.

Best video for removing the oil pressure sensor..thanks a million sir
Thank you for this video!!! I was able to fix mine because of it! 2007 Chevy Avalanche LT with the 5.3L Vortec V8. Wow though, this is a hell of a job to do. It took me 3 attempts to get it and a lot of swearing. There is literally no room back there. Though it would be easier if you disconnect the fuel line(which I did not do). I actually broke the connection stem on the sensor when taking it off so that was the point of no return. You really just have to be patient and take your time with this and you will more than likely cut up your hand and bruise your arm because of the hood support there. I used the sensor socket and then a 1/2 swivel followed by a 3 inch extension and because i only have a 3/8 wrench, I had to use a 3/8 to 1/2 adapter then my swivel head wrench. I when using the wrench to loosen the old part is when I snapped the sensor stem so when I put the new one on I had to use my hand on the extension to tighten as much as I could then I used the wrench to snug it. Be very careful when doing this, make sure the socket does not come up and angle or you will break it. Also fishing that damn filter out is a pain in the ass!!! Overall it was a 1.5/10 experience and I hope I never have to do it again! Sorry for the long comment.
Wow, I've seen some clips where they take the manifold out to repace the sensor.
I know i will be doing it this way for sure!!
Thanks for sharing your informative & helpful clip👍👍👍👍👍
👍👍It was great telling your viewers about the screen. Of course I already knew it had one.
Hey Richard, of course! Hope you liked the vid!

Excellent quality video. Thank you!
Thank you, solved my low oil pressure light! Very tricky to get the socket on the old sensor, not a lot of space to work back there. TQ wrench with narrow arc-swing really helps
Great job Mike. Factory manual says to pull the intake but not necessary. I always thread in an oil pressure gauge before replacing sensor just to make sure mechanical pressure is correct and that the gauge wasn’t correctly reporting low pressure
Thanks man! Yeh, that's a great tip to mechanically check the pressure. Thanks for watching!
~Mike
How did you go about testing your system mechanical ?
Thanks you made it easy to understand
A 27mm 6 side socket will also do the same as the fancy socket
Any time you have a threaded shaft with a hole in the middle, torque to spec is a got to do. The 2 types of things I make sure to torque are brake caliper banjo bolts and pressure sensors. Neither of these do you want to leak or break.When I hit 70 years old {72 now}, I started loosing some muscle mass, so now to be sure I'm tight enough, I torque damn near everything. WHICH MAY BE A GOOD THING. {That I torque everything, not the getting old part, that sucks}
Hey Terry, thanks for watching! I try to torque everything too. Better safe than sorry!
Mike Becker, Senior Instructor
Thanks you! This is a big help 👍🏼
Very helpful video thank you
Thanks for the video. Had to help my dad because his hands are too big 😂
Always like your vids Mike!!
Thanks Bill!!
Mike Becker, Senior Instructor
Good a great job video. Good work. Like your channel you are not a show off and a lot times you take advice from your comments. Good work.
Thanks a ton man! Nobody knows it all and the ones that say they do are lying. I just love the community and sharing and learning with everyone. One big, messed up, greasy family ;)
Mike Becker, Senior Instructor
Great job Mike!
Thanks dude!
Mike Becker, Senior Instructor
Hi Mike, I hope you're doing well. Thanks for the informative video.
Hey, thanks! I'd doing better than I deserve! Hope the same for you and your family :)

Good teaching Mike 👍🙏and thanks for teaching us
Hey Salvador, thanks for watching!
Mike Becker, Senior Instructor
Hey Mike, great work! Must helpful!
Hey Nancy, thanks for watching!
Mike Becker, Senior Instructor
Very informative video. Just what I wanted to know. Thanks. Subbed and liked.
Timely and helpful. I need to do this soon and was not aware to look for a screen. With little room and doing the job by feel - that alone might have led to a fail.
Thanks a bunch!
What year? I believe the screens didn’t start until mid to late 2000. The screen is 2-3$ if you have one just get it regardless. Removing it with a pic like he did usually ruins them. Honestly not sure how else to remove one though.
From what i've seen it's mostly on the AFM systems. Either way, like Thomas said, maybe pick one up just so you have it just in case.
Mike Becker, Senior Instructor
A trick to remove the screen is to use a long bolt. If I remember correctly it is 1/4". Screw it in several turns and pull it out.
Great video. If you are working on an older truck, I would recommend to confirm the oil pressure gauge and scan tool data match (or gauge sweep test). There has been so many gauge cluster issues in the past that effected many years and GM models. 👍
Hey Jim, thanks! You are totally right, GM clusters in those years had a bunch of issues for sure!
Mike Becker, Senior Instructor
this will help me a ton! my oil pressure gauge just started showing 80 (which is max on my 2004 silverado) no matter if i’m idling or driving.
Did it had the oil filter or screen?
Thanks for the video 👍
Thanks for watching bud!
Mike Becker, Senior Instructor
This video was very well done thanks
Thank you very much Kevin!
~Mike
Glad you enjoyed it!
Thanks for watching!
~Ryan
Simple and Great 👍
Thanks for watching Gerardo!
Mike Becker, Senior Instructor
Thanks for the video Mike. It's a good idea to use the torque wrench on as much as you can, or as many specs as you have for fasteners. I really hate it when tech's and installers don't use a torque wrench on tire/wheel lug nuts!
There's spec for a reason, right Mike!? Thanks for watching!
Mike Becker, Senior Instructor
@@GoTechTraining My dad is a retired A&P mechanic and Inspector. He taught me the best rule of thumb if you don't have a torque wrench handy while working on a car: hand tight, then snug with a wrench or socket, then 1/4 turn for everything that doesn't include head bolts, tranny bolts or the integrity of the frame. He's done it that way on his own vehicles for over 55 years and no problems yet. I've done it that way on mine for over 30 years and no problems yet. And I've replaced two engines in my own vehicles when they hit 200k+ miles.
Thank you.
good job thanks have changed several of them
Thanks for watching! You do them without pulling the intakes?
Mike Becker, Senior Instructor
@@GoTechTraining yes. It's so odd I had installed 2 or 3 when someone said that they sure wished that there was a way to install without removing intake I didn't say a word it was one of the shops that knows everything
wow that changed fast! i think service info says to pull the intake a lag bolt or 8mm bolt can extract that filter a topside creeper would work nice on that job hope all is well mike!
Hey Scuba, thanks for watching man! Yeh, the book says to yank the intake...craziness! A topside creeper would be nice. I use a huge sheet of foam I got a while back, works ok.
Mike Becker, Senior Instructor
DId this today thanks to your video - Unfortunately I am still sub 20 PSI on oil pressure so the pickup line o ring is next...
Great info as always Mike. I happen to have a 6.2 L GMC. Thanks for all you do friend.
Hey William, thanks for watching!!!
Mike Becker, Senior Instructor
I did mine a month ago in cleaned surface with brake clean and air before removal.
That's a great tip James, thanks!
Mike Becker, Senior Instructor
Is it true that the only vehicles that have the filter under the sensor are the ones with the afm system ?
Hi Oz,
You are correct, the purpose of the filter screen is to filter out contaminants from entering the AFM lifter system. I have not seen the screen on Non-AMF vehicles.
Ryan W, Technical Instructor
Just to clarify, is the sensor oriented vertically or horizontally? And thank you for making these videos!
Very common problem on those cars! 👍
For sure Nick, for sure!
Mike Becker, Senior Instructor
Hey man is this the same process for a NB 07 4.8L? My sensor is bouncing between 0-80
If it weren’t for you and Scanner Danner, Mike, RUclips just wouldn’t be that good.
Hahha thanks Dave, I appreciate it. I think RUclips would still do alright without me though ;)
Mike Becker, Senior Instructor
@@GoTechTraining I agree with Dave's comment and would add Eric O. and Ivan to the list. I found your channel because of Eric O's recommendation. You guys are all awesome' Thanks for all you do. 👍👍
I'll soon be down and out bad my 2011 gmc sierra has an oil sending unit behind the block I tried to change it recently and stripped the new sensor now I can't even get the old one to start back in and it's super difficult to find a 16mm x 1.5 tap would this work if I could find the right tap?
Mine went out today. What a coincidence haha
Talk about perfect timing huh! Thanks for watching
Mike Becker, Senior Instructor
27mm socket will work as well if you don’t want to spend $16 on the specialty socket.
Hello Prosper,
Good tip! Thanks for reaching out!
~Ryan
Thanks 🎉
Hi are you still there??
I have a 2012 avalanche and a different video says gotta remove the manifold . ???
What is the other sensor visible at 1.25 in this video called
Great video I replaced my oil pump with a high-volume oil pump I replaced my pickup tube I replaced my oil sending unit end filter my gauge is still descending to zero telling me I have low oil pressure I hooked up an internal oil pressure gauge at cold start I had 80 lb of oil pressure warmed up to 210 running temperature I was idling at 59 lb of oil pressure if I have this kind of oil pressure why am I still getting the low oil pressure warning in my vehicle is the oil pressure relief valve in the oil pan causing my low oil pressure at this oil sending unit any good information would be nice thanks.
Anybody know where to find a video to replace the oil sending sensor filter?
Loctite blue? On threads?
Would the sensor on my 2014 gmc sierra 1500 be located at the same spot as on this one?
Yes is will be in the same location.
~Ryan
Going thru the problem as we speak
Good luck!
I crawled in there and looked at mine with a bright flashlight and decided to pay for mine to be replaced. Neck,left arm,and lower back problems kept me from trying to do it. Getting older older usually comes with challenges!
Mike, I've got a 2009 Express 2500 4.8L where the oil pressure on the console is no longer working. Would my sensor be in the same place as in the video? Thanks.
Hey Ron, yes i'm seeing it in the same spot on the 4.8L. Should be a pretty simple job if you can take the engine cover off from inside the van.
@@GoTechTraining Thanks
Well reads low 1 time and shut off cranked back up and shows normal pressure. 2013 5.3
Mines was stuck on 80 just swapped the sending unit but still on 80. What do you suggest I do next ?
Try flicking the needle on the gauge, sometimes it gets stuck
So do you put the filter screen in or out? What happens if you don't use the filter??
Hi John,
The filter is there to filter engine oil for the VLOM or cylinder deactivation system. I recommend replacing or cleaning it anytime you remove the oil pressure sensor.
Thanks for reaching out!
~Ryan Wilsing
How do you know if it was in there? I took mine out last night and couldn't feel a sensor but I'm also worried I might have pushed it down into the motor
Test first sensor?
where the heck is it? I have multiple Chevrolet shop manuals and they all make it look like it sits just behind the intake manifold on a flat surface, but my 2004 5.3L does not have anywhere for it to be, but I have the exact problem that the vehicle in the video has - the second you turn the key to "on' the oil pressure gauge pegs at ~80
My new brass oil pressure sensor didn't come with a crush washer.
What did y’all do to fix it
I'm not sure what you mean? This video is to replace the oil pressure sensor
Very basic common knowledge for a "GOOD" mechanic as are "General Messes" AFM system that was a failure I just do a delete for them, just one of GM's laundry list of problems!
Hey Greg, thanks for watching! Ahhh yeh the wonderful AFM system.
Mike Becker, Senior Instructor
You forgot to verify that you are getting proper oil pressure indication while leak checking. In my case I just got done installing a new oil pressure sensor on my 2000 GMC because the stock one was leaking oil. I Installed the new sensor, no leaks noted and it was reading 40 psi on the gauge. Turned off the engine and did not drive the truck the next day. On the following day, I get in the truck to move it and the oil pressure reads past 80psi with key switch on and off. what the heck just happened?
So this r&r doesn't require too much swearing ?
Swearing is optional! LOL
If you have small hands and long arms - then no. I swore like a Sailor on the first one and it will probably be the same for today's replacement. Can't complain though, only the 2nd one in 352,000 miles and the engine has never been touched !
@@HairMetalJintz 😅
✌️👍
And the first comment goes to Arthur!
What’s the sensor that sits right next to the oil pressure sensor??
Hello Erin,
That is the Camshaft Position sensor.
Thanks for watching!
~Ryan
Thank you!! I appreciate the response!
What size socket to loosen the camshaft sensor i need to loosen to get the socket on the oil pressure sensor
Seem simple
You should always blast brake cleaner and air around it first to avoid knocking sand in like u did lol
Yes, for sure Tyler. Messed that up on this one!
~Mike
Im not judging i had to snap an old rusty fulll of water sensor off my fresh rebuilt cammed 5.3lol
Sounds super fun! 😂 End up having to drill it out?
~Mike
Nope i slapped it in in a hurry from a crusty old motor i had in the backyard just so i could throw it into my reg cab short bed. So i buttered the threads up with liquid pipe sealant and didnt put it in tight. I used needle nose vise grips and went 1/16th of a turn at a time hahah
Im trying to buy a gm OEM sensor and a proper socket for it
Can the screen fall down into the motor?
Hey Brent,
Not unless it was broken into pieces. If it is missing it may have not been equipped with one. Not all early engines had them.
~Ryan
That screen is just silly, leave it out. As I remember, 6.0 doesn't have it.
If you need a screen to stop sludge, you've got bigger issues than a sender replacement.
Hey N V, thanks for watching! I think it was intended to keep stuff outa of the AFM lifters...but yeh, you're right. IF it's plugged you probably have bigger issues!

What do you call SUBSTANTIAL and KNOWLEDGEABLE the answer is Go Tech Mike Becker
Thank you very much helpful video information brilliant video amazing tutorial. Take care and have a great day
Go Tech Mike Becker
Please need voltage drop testing Video
Please Go Tech Mike Becker
From Nick Ayivor from London England UK 🇬🇧
Hey Nick, Voltage drop test huh!? Real world failure or can I make something up to demo it?
Mike Becker, Senior Instructor
You will not believe this a Chevy 3500 with 6.0 came in today bad oil pressure sensor this one stuck high as well
I have 27 mm but it seems way loose
I can’t even get a socket on my sensor
1:25 - Never pull on the wires to unplug any connector! I hope this is not how you teach your students to unplug a them!
Hey RP Smith, you are 100% correct. I should not have yanked on them for sure. I was holding the camera with one hand and trying to unplug with the other and I slipped up and yanked the wire. I'll do better, thanks for calling it to my attention.
Mike Becker, Senior Instructor
@@GoTechTraining -- We all slip up from time to time and need to own up to it every time we do :o)
wait? no impact wrench? lmao.
Hey Richard, i'd be a little worried about tweaking it and breaking it off. So nope...the old fashioned way on this one hahah!
Mike Becker, Senior Instructor
I hope whoever thought it was a good idea to put those oil pressure sensors where they put them on these engines got fired over it. I can’t speak for anybody else, but for me personally, these are a giant pain in the ass to change out.
Hey Dmorley100, thanks for watching! Yeh, they are a pain to get to. Maybe that's why GM says to pull the intake to do them...but a little bit of patience and a wobble extension gets it done.
Mike Becker, Senior Instructor
@@GoTechTraining I hear ya. As tight as the space is to get those sensors out, GM can go f*** theirselves if they think I’m pulling that intake off to change that sensor.
Less than an hour? It shouldn't take more than 10 minutes, max.
hahah sure, for someone with experience, I agree!
