Thanks buddy, for showing me the secret on that downstream sensor. You saved me a headache!

[@ofthunderministries]

Finally someone says the actual size you need to unbolt them, I don’t have many tools so I’m only buying as I come by

[@dude1313525]

I was lost on where the second sensor wire came up. This helped so much, thank you!

[@learjet7491]

Great job mentioning and locating that 2nd sensor, you did a lot of other work on your truck , excellent, that truck will stay in the road in good shape with the efforts you made, excellent!

[@mr.non-obvious7872]

Hey mannn, you’re a life saver. I know their is some kind of way to make it easier for people like me to toss you some cash flow for your troubles. We sure aren’t loaded, but a few unexpected bucks are always nice to receive for lookin out for your fellow man.

[@JorgeS.]

You're welcome. I just wanted to make the video to help the average person without having to go to a dealership or pay a mechanic. My cash app is listed on the bio.

[@EnriquePerez-pd1oz]

​@@JorgeS. what's the purpose of those sensors

[@EnriquePerez-pd1oz]

Is the check light on in my truck he said it was the heated oxygen senor

[@legaltingz316RHD]

Thank you very much for the info. I have the same model of truck, but mine is automatic and I’m having the same problem and the mechanic want to load of money so I think I’m gonna do this myself. I’m gonna watch your video again and again till I get it, right.🤩🤩🤩

[@lifeguard92646]

thanks brother very helpful regarding the downstream sensor plug

[@AlanDickerson-r1g]

Thank you so much

[@nuedles337ify]

you’re the man…needed this bit of info…thanks👍

[@nomarniram4176]

Right on bro, thanks for confirming where the down streem location is and how to get to it. No one else seems mentions it. Thanks for the info.👍

[@selbor7]

Thank you asked a few people nobody new ! Tks again your 🤓 smart

[@robertbeltowski2819]

Thanks, I have the same year. My 02 sensor Bank#1 - sensor #2 is bad also. But I only have 89,000 miles. Well after trying to remover the two nuts holding the sensor on, they both broke off. Now what the heck, I guess I will try to drill and retap them.

[@SamFishback]

Finally! Someone with my exact model!

[@1975dbryant]

Good looking out. Gonna change that 2nd oxygen sensor today. Appreciate the heads up on this one.

[@jdogdaddy]

Thanks buddy - good and helpfull locator vid!

[@samgirton4312]

This video is so helpful, thank you for posting it! I have an 02 Tacoma just like this one. Does the upstream sensor have the same part number as the down stream sensor or should I look for a different sensor for downstream?

[@JorgeS.]

Im glad to see that the video is helpful, the part numbers for the up stream and downstream are different. Part numbers are also included in the video description and part 2 installation video.

[@THEVALKERY95]

Thank you for the video man!!!!

[@BrenyelRonaldo]

Great video! but can someone tell me if Toyota Tacoma 2004 PreRunner has 4 Oxygen sensors?

[@JorgeS.]

@@BrenyelRonaldo it should have 2 o2 sensors up stream and down stream

[@rappingloon726]

Exactly what I needed to know.

[@finfish260]

How do you unclip the connector? The connector body is mounted to the sheet metal with a plastic clip. I can't get it out of the sheet metal and I'm afraid I'm going to break something.

[@JorgeS.]

I used a panel/trim removal tool to remove it you can probably use a flat head screw driver as well.

[@renecordova325]

I think I will cut the wires and solder them back together, rather than remove carpet. I have lots of experience at soldering

[@trevorpetersen6919]

Do you disconnect the battery before installing it?

[@JorgeS.]

@trevorpetersen6919 I would recommend disconnecting the battery as it will also clear any codes you have.

[@mgasapmg3092]

Thanks that helped a lot your awesome!

[@JorgeS.]

Glad it helped!

[@kingsleyosunkwor819]

Hello please am a mechanic, my bus Toyota Hiace bus 3RZ FE engine has its oxygen sensor disconnected from the clip, I can’t find the clip anywhere, and it been consuming a lot of fuel, I mean a lot, please can you guide me, really need to fix it

[@oswaldo777100]

hanks great informative video

[@ldr4278]

Excellent 1

[@alpinewhite]

Thanks for the video. Pls record future videos horizontally. Look at your videos on a laptop and you'll see what I mean. Thanks.

[@JorgeS.]

Thanks for the tip

[@RonKris]

On a 2005 Tacoma upstream sensors are the same? Is bank 2 or 1 the same?

[@JorgeS.]

They are both different part numbers. Info for the part numbers are in the description.

[@howardhicks8202]

Thank you!

[@gloriastafford4120]

Help on something thanks for the video I change both of the sensors and my trucks still jerks when I pick up speed what else can be wrong with it

[@JorgeS.]

I would start by checking for any codes as well as spark plugs and coils.

[@Hj61S827]

I let some ding a ling “work” on my 2000 4x4 taco. He broke 1 post off the bank 1 sensor and left my sensor harness unplugged and hanging. I got a new sensor, but I cannot for the life of me find where the o2 sensor harness connects to. Could you tell me where that harness leads to? I will literally cash app you if you can respond in the next 24hrs

[@Hj61S827]

For anyone in the future, the 2000 Tacoma 4x4 with locker, the bank one harness is on top of the transmission, it’s viewable once you feel it, but only from the drivers side.

[@JorgeS.]

It should lead to the inside of the cab

[@Ernestolopezhernandez1979]

Thankz

[@vickiejohnson8816]

Can truck be driven safely with the light on?

[@JorgeS.]

Yes you can drive it but I wouldn't go to long without fixing the issue.

[@kumaquattro]

Thank you

[@MarcoRodriguez-ho3nt]

Is your Tacoma a 4 cilínder or 3.4 engine???

[@JorgeS.]

4 cylinder

[@avistar9664]

Both sensors same part number ????

[@JorgeS.]

No they are not. The part numbers are in description of video for up stream and down stream.

[@jimichan7649]

Very nice!

[@thefireking5729]

Someone already rounded my bolts off so they ain't 12 mm anymore for the bank 1 O2 sensor

[@martinserrano6091]

Hey I change bank 1 sensor 1 for P1135 can bank 2 give you the same code?

[@JorgeS.]

No you should have a different code if you need bank 2

[@martinserrano6091]

@@JorgeS. thank you much

[@realJohnLab]

Crap.. I have to change this one again and forgot it’s the one that goes through the floor. 220k nice. Just hit 313k. Thanks for the reminder of location.

[@JorgeS.]

313k that's good to hear alot of life in Tacomas

[@Emiliopedo]

Do you know if this will fix the code p0420 I want to buy the cheapest solution it can be if not I will need to buy a new cat hope not because is over 700 dollars

[@JorgeS.]

I don't think it will work for that code but i heard there are ways to clean your catalytic converter. I would try that first before spending $700.

[@CarlosMorales-wk5bg]

Bank 1 is the upstream

[@JorgeS.]

Yes

[@joesezzz4324]

I have the same trk its throwing 2 p0036 after replacing both cat's & sensor's any thoughts?

[@jeffrey5703]
