Thank you for all videos. I have 2002 Avalanche, 2003 Escalade, 2005 Yukon 2500 and 2008 Express. I replaced 3 oil pressure sensors on my 2008 Express for past 6 month. Fist sensor was from Amazon. Sensor start leaking oil throw electric plug after 4 month. It is easy to replace oil sending sensor on Express. It will be challenged to replace this sensor on Avalanche (2002 Avalanche required use a special socket). I replaced wit Dorman sensor from Amazon ( I think that was knockoff) . Sensor stop working after a couple month. I went to dealer, purchased overpriced sensor. GM sensor works good, no complains so fare.
You like the trucks more than me haha. Never use the cheap sensors. I did the same thing and now I'm going to have to replace it with the Delphi sensor.
@@MattsShop GMT800- good trucks, affordable and easy to work on it. You need 2 jack stands, bottle jack and basic tools. and scanner. Only one problem- break lines. I had to replace lines on 2 Escalades. Newer donned this before. I replaced break lines on 1st Escalade. Its takes a 2 days. On the second Escalade - 1 day. Dorman makes a good stainless steel lines kit ($100-130). Thanks for your work.
I have a 2007 tahoe, I kept getting low oil pressure alarm, with the help of youtube and ppl. Like you I diagnosed what the problem was and fixed it myself.
Oh man where do I start lol. I thought it was the oil pressure sensor so I changed it out the easy way just reaching back there and having the right extension and swivel attachment, but that wasn’t it. Then I changed out the little pressure filter that goes inside the oil pressure sensor hole and it was caked so I changed it out and that fixed the problem temporarily. It would throw out the alarm a week later. I got really good at changing those out really fast lol. The root of the problem ended up being that my coolant was leaking into my oil and that it why the filter kept getting clogged. So I figured that I had a blown head gasket. I had 249k miles on the tahoe at the time this was just a few months ago. I watched numerous tutorials on here to figure out how to do it. There is actually a really good one that showed step by step and so I went ahead and did it. A weekend job took me 10 days. But I did it and did it right. I changed out the head gaskets for both sides, the air intake manifold gaskets the exhaust gaskets which was a pain. New fuel injectors and spark plugs and cleaned out the carburetor ect. I spent probably around $700 in parts plus tools I needed. I just took the tahoe to Mexico on a 20 hour drive through dirt roads that were in bad shape and on the way back it took me 21 hrs to get back from Guanajuato because of the damn traffic and construction and with no problems except that my ac went out. Right now it has 254k miles on it. I hope to make it to 300k and more.

Coming here from owning a 90k1500 Silverado. Recently bought a 03 6.0 Silverado to keep the miles off my 90 and now almost want to do the same to the 03 haha. Genuinely appreciate you and your videos to help me diagnose and find sny possible issues that may arise with my 03 and my dads 01 tahoe. Recently had a bad idle/stalling/sluggish takeoff issue so beforei found this video it ended up being just the MAF sensor, dirty air filter and dirty throttle body. Cleaned them up and runs absolutely amazing now. Will continue to follow up on your videos to these trucks to keep my in great shape❤️🤝🏼
Thanks so much for these videos, dude. I have a 1500 and 2500 2004 sierra, and these videos are great help. I'm having electrical issues. Have you done a video of all the ground locations yet? Thanks again
Could you list/cover [ common [mm] Bolt Sizes & its Torque specs ] such as, Thermostat bolts, oil pan, oil cooler gasket & oil drain plug bolts, water pump, etc components on 1999-2002 Chevy Silverado 1500 V8 5.3. Thanks MATT subbed as well v.
Subscribed! Thanks for the good content. I got a 2004 Escalade with the 6.0 Vortec. It takes a while to start in the morning, but then it’ll start up normally if I decide to start it up again right away. If I let it sit for a few hours, then it’ll take a few cranks for it to crank over. I seen this video you made and you mentioned the Cam Shaft Position sensor will make it take long to crank over. Thing is, I’m getting codes for, ‘P0651’ & ‘P0452’ It’s driving me crazy. Sometimes the codes clear themselves out on their own and come right back. & yes I know one is a 5 volt reference code, and the other code is a Evap code for the Fuel Tank Pressure Sensor. But I’m just wondering if It’s that simple as ohhh I need to replace the Fuel pressure sensor, & thats why possibly my truck is taking longer to start. I’m just wondering if that’s the right direction to look at. Basically what I’m saying is, would that sensor be causing that long cranking? Would love to hear your thoughts. Thanks! Oh,, & I checked the wiring harness around the engine bay, everything looked well protected, I know there’s a spot on the side where the battery is, that the harness runs over the head of the engine that is prone to damage, and that looked fine, it’s on a plastic clamp sitting nicely not touching the motor. Sooo idk 🤷♂️ Any thoughts helps Thanks!
what do you do on an aftermarket DBC (nick Williams) throttle body when the TPS won't go below .04 without drilling out the mounting holes a little bit?
Hey was wondering if you could help me with some information? I have a 07 Chevy Silverado and a lot of the fuses in the main fuse box under the hood is grounding to the motor some people say it supposed to and some people says it is not supposed to? So my question is any of the fuses supposed to ground in the main fuse box back to the motor?
Hey Matt I have an 00 v6 sierra. I’m having a slight hesitation at start up when pressing gas pedal it’s very sluggish until I get past 5 mph than it takes off. When I press gas it almost feels like a misfire or exhaust is clogged I can floor it and it won’t go at all till it goes past 5-10 mph. I’ve gone thru 2 fuel pumps in last 6 yrs. Replaced fuel filters and oil service done every 3k and spark plugs regularly done also any suggestions?
Hi, i have 2001 vortec 8100. I have issue with acceleration, it feels heavy but eventually picks up and go. Another issue is whissing sound from the exhaust when i push the gas paddle. Can u suggest what i shall look for?
So with the camshaft position sensor if it doesn’t start on first try but starts right up on the second crank what else could it be if I’ve replaced the camshaft position sensor and it’s still doing it? I’m assuming the crankshaft position sensor but I don’t want to go just replacing sensors if they aren’t actually having problems
Hello I have a massive problem with the cam shaft position sensor code p0342. I have already replaced it with the crankshaft and I still have a long crank start. I also ran the wire from the sensor directly pin to the computer and still same problem. Any idea on what it would be I what I could do?? Would be very much appreciated. Thanks!
I would look at the signal at the camshaft sensor with an oscilloscpe or at least a multimeter and make sure you have the voltage that's supposed to be there. You gotta get Delphi sensors.
Do you know what this means? I just replaced my mass airflow sensor cause I got a P0101 code on my truck so I replaced it and I still had the code. What do you think it could be 03 Silverado 1500 HD 6.0.
I have an issue with my 04 trans. Recently rebuilt, at low rpm in od it sometimes acts like it slips it'll downshift then shift up back forth back n forth
Hey Matt, I have a question my 2006 gmc sierra at idle it gets stuck on 1000-1500 RPM until I hit the brakes and it calms down and then revs back up to 1000-1500 RPM. I’ve changed o2 sensors and nothing any ideas?

Excellent! 03 burb 285k. Never dealt with any except oil pressure and knock sensors. But awesome to know these others. Thank you!
Can you do a video on getting out of anti theft mode
Yea all the car thieves want to know
Thanks! Your videos are always so informative!
You're welcome!
🙏🙏 very informative! I think we all needed these videos about these gmt800 trucks. I’ve watched all of them and subscribed 👍
Thanks so much for these videos, dude. I have a 1500 and 2500 2004 sierra, and these videos are great help. I'm having electrical issues. Have you done a video of all the ground locations yet? Thanks again
You're welcome. Nope I'm doing that next: ground locations.
Best breakdown I have found GJ Matt, I run a 2003 Silverado myself.
Thanks man I appreciate it nice year!
I have a 2006 gmc sierra 1500. Thank you for everything
You're welcome! Basically the same truck!
I love the 03 tahoe things a beast
I bet it is!
Right on Matt!
For sure! 🫡
Thanks for sharing!
You bet!
This is an awesome video. How's about telling us what the readings for each sensor should be? 👍
That sounds like a good part 2 👍
Man great content!!!!
Thank you!!!
Love the videos cause I have an 04 and 06 silverado
Awesome! Keep them runnin
These old trucks are way better than all the new 2021-2024 junk Chevy is bringing out
Damn dude, I wish I made this video lol. Freaking awesome nice job.
You are my Hero
You're my hero!
Luckily my 05 has been flawless, but thanks for this.

Hey question I have a 2001 Chevy Silverado 2500HD that runs good cool but starts to want to die when it gets hot any ideas?
Enjoy your videos Matt
Does a 2006 silverado 5.3 have a PCV valve
Thanks, yes it does built into the drivers side valve cover.
@@MattsShop I found out I have to replace the driver side valve cover because the pcv valve is built in
Thanks Matt
Good stuff! But doesn't the Silverado have a transmission temp sensor? Thanks for sharing.
That's not an engine sensor. 🤣 It does but there is no gauge on the 1500's it's monitored by the computer and you get a light on the dash.
What are the symptoms of a bad knock sensor?
Everytime i had to replace exhaust sensor ive had to retread the opening , parts stores have the tap to retread them holes
Yea, they get stuck in there and damage the threads.
Had to replace throttle body on my 03 2500 because in cold weather it kept going into limp mode
I cut my cats so I don’t have to worry about the o2 sensor 😂
You have to worry about the upstream sensors!
I just perched a 2003 gmc sierra 1500 hd 6.0 that says Vertec as well. Would this videos help me fix what is needed on this kind of truck
Yes, the 4.8, 5.3, 6.0 Vortec V8 engines are basically the same thing.
what do you do on an aftermarket DBC (nick Williams) throttle body when the TPS won't go below .04 without drilling out the mounting holes a little bit?
Is driverside or passenger side Bank 1 sensor 2..? On this truck. Thank you
Driverside Bank 1
Passenger Bank 2

Your the sht bro 🫡
Haha thanks, I'm wherever you need me to be. 🫡
What scan tool do you recommend that has all live data option
Hey matt, quick question I have a 02 Sierra and the rpm gauge stop working a couple days ago. Would you think this is a sensor or a cluster problem?
This the same for a 09 Escalade? 6.2 flex fuel.
I’m having electrical issues with my cluster do you have any advice
Start with grounds!! There's a couple of fuses under the hood for the dash cluster. The dash clusters can have solder points that go bad.
@@MattsShop what ground straps should I buy would u have an Amazon link? Before I check out the hood static ground strap
Do you know what this means? I just replaced my mass airflow sensor cause I got a P0101 code on my truck so I replaced it and I still had the code. What do you think it could be 03 Silverado 1500 HD 6.0.
I changed the cam shaft and fuel pump and it still struggling to start also after fuel pump replaced my gas meter don’t work
Thankyou
You’re welcome
I have an issue with my 04 trans. Recently rebuilt, at low rpm in od it sometimes acts like it slips it'll downshift then shift up back forth back n forth
I would talk to the rebuilder. That doesn't sound right.
I find that stalling issues on these are normally due to a dirty throttle plate.
Yes, that happens a lot too! The throttle gets sticky and it stalls.
What size socket is the oil pressure senser?
Its a special socket
$15-25 in any auto parts stors.
Hey Matt, I have a question my 2006 gmc sierra at idle it gets stuck on 1000-1500 RPM until I hit the brakes and it calms down and then revs back up to 1000-1500 RPM. I’ve changed o2 sensors and nothing any ideas?
The first thing is to clean the throttle body and make sure it's not sticking. It could be a fuel related issue.
@@MattsShopThank you!
You left out the fuel tank pressure sensor, which looks similar to the map sensor on the back of the intake manifold .
Fuel tank pressure sensor isn't on the intake on these trucks. Maybe the flex fuel vehicles.
@MattsShop no the sensors just look similar is what I was saying.
Great
My code says Bank 1 lean any ideas
Something on the Driver's side exhaust isn't getting enough fuel. You gotta check the fuel trims with the computer.
Was that the p2270 code you got.?
OE ONLY!!!!
I AGREE!
signs of a bad temperature sensor
You Forgot the Oil Level Sensor in the oil pan 👍🏻
I said it at the very end
@@MattsShop, oh my bad, missed that.
