Here, I show you how to replace the Oxygen (o2) sensors on my 2000 GMC Sierra 1500. This should be the same process across all:
1999-2006 GMC Sierra
1999-2006 Chevy Silverado
Caution! Make sure vehicle is cold, otherwise, exhaust will be hot.
Sorry about the background noise and the pulsing light. My Light bar pulses when recorded and there was lots of construction going on on the main road!
Items Used for my truck, parts vary:
Upstream Oxygen Sensors (Truck Uses 2) - amzn.to/3oYxzDM
Downstream Oxygens Sensor (Truck Uses 2) - amzn.to/3wGX4wa

@ufixitauto5237 3 года назад

Some people consider them to be a tune up item, like spark plugs and wires. So you can do it if you want! Can't go wrong swapping it out, BUT the majority just wait for the check engine light to go on to swap them out!

@SuggonDeizNutz 7 месяцев назад

Outstanding video! I put a long breaker bar on them and still can't break them loose. Did you have to use a torch on any of them to heat them up before they broke loose? I would assume not, since you didn't mention it. I don't even live in the rust belt! They are original though on my 2000 GMC Sierra 2500 with 125k miles.

@ufixitauto5237 7 месяцев назад

On my '05 Yukon XL the connector for Bank 1, sensor 2 is the hardest part of this job as you need some baby hands & forearms to get at & seperate it. For those that with those handly little O2 sensor sockets (well worth the $5 on Amazon) in my experience more often then not the sensor will not budge & even a good penetrating oil will not help so take a propane torch & heat that suckered up being cautious of any fuel lines or wiring harness.

What were the symptoms was it hesitating or stalling or no acceleration no throttle response?

@ufixitauto5237 3 года назад

Slightly surging engine and the check engine light saying that the Oxygen Sensors were suspected bad 😂 BUT, it turns out that the intake Manifold Gaskets cause an O2 sensor check engine light. I made a video on it and thats what fixed my issue! It's very common with these engines. I wanted to replace the O2 sensors anyways as part of my tune up on the truck since the truck has over 260,000 miles on it 😁

Hey loved your video so I'm going to try to replace one of my O2 sensors. How do I look up online which sensor to buy? I have a 2005 GMC Yukon Denali. ? Worried that I'm going to get the incorrect one.

@ufixitauto5237 3 года назад

Do you have a check engine light telling you to replace it? If you do, it'll tell you which bank and which sensor needs replaced. To make it easy, you can go to a website of a local parts place like Auto Zone or O Reilly, put in your car info and then look up oxygen sensors. Amazon tells you which parts are compatible with your car if you have your car info stored there. They usually tell you if they are Upstream or Downstream sensors. Just grab the one you need :) in the video, I describe how to differentiate between the two :)

@bubbashursh262 10 месяцев назад

My GMC has only 82,000 and the check lights keep coming on and off. Had 2 test check on truck and it comes out with bank 1 & bank 2 senor readings. Do they go out that quickly on a GMC? And, you bought each sensor for $40? Over here in California, auto zone want $175 and $77 + taxes bank 1 & 2 , upper & lower. Bosch not GM parts. Thanks for your video teaching.

@ufixitauto5237 2 года назад

Yes I purchased them 40 dollars each! Auto Zone inflates those like crazy. Check my affiliate links in the description. And no, I wouldn't say that it is normal haha. At least not in my experience anyways. That's often the sign of either bad O2 sensors or intake Manifold Gasket. No way for me to know haha

My 2003 GMC Sierra 1500 has a Vortec V6 which evidently do not use the GM AFS 138 sensors as shown in this video. I removed all four sensors from my truck and discovered that all four were identical as they came from the factory. Since the GM AFS 106 (also shown) do appear to be correct, I'm assuming that I should use four of these as replacements. Am I correct?

Just bought an 2005 Suburban, yesterday. Engine light came on today for the oxygen sensors. How long can I drive before replacing them? A month? Thanks!!!!

@ufixitauto5237 2 года назад

Everything is subjective to the car. Typically, in my experience, bad O2 Sensors cause bad fuel economy and sometimes surging engines but it has not left me stranded and I left it running a while with bad O2 Sensors. BUT, I should also mention that even though the check engine light showed O2 sensor codes, the issue was the intake Manifold Gasket. It's a very common issue with these LS engines. So, if you replace your O2 Sensors and it doesn't fix the issue, then I would look at that :)

@manuelbocanegra2644 2 года назад

After replacing sensors will the check engine go off on its own or does the battery need to be disconnect to reset check engine light?

@ufixitauto5237 2 года назад

Drive it around enough and it should go off if that was an issue. Or just disconnect the battery for a minute and see if that did away with the code.

So my connector wont connect for bank 1 sensor 2. Dont know why tho. Any ideas?

@ufixitauto5237 3 года назад

Hmm, do you know if that's the fault of the sensor or the connecting wiring? It could be a bad sensor connector, so you can try to plug in the old sensor to see if it connects just fine. Best case scenario is you just need to change out the sensor, worst case scenario is you'll have to cut and splice the wiring harness off a junkyard donor.

@luisv8413 3 года назад

@@ufixitauto5237 found out that the Bosch sensor that I tried installing was the incorrect sensor. Returned it and drove 15 miles to another location for the OEM o2 sensor. In theory it was the same sensor but out of the box the electrical connector at the end of the sensor was not the right fit. It did not click in. So yea you were right haha, Ihad a small scare there.

How do I shut the check engine light off?

@ufixitauto5237 3 года назад

Remove the battery for a couple minutes and it should reset it. If the issue is gone, then the check engine light should be gone. If the issue is still there, then it'll turn back on. If your check engine light is still on after disconnecting the battery and you still get O2 codes after replacing all of the O2 sensors, then check out my video on replacing the Intake Manifold Gasket because that may be what you need to do. It's a common issue with these vehicles. That's all assuming you have the same type of vehicle as me! 😂
