In this video I will show you how and Oxygen Sensor aka air fuel ratio sensor works, how the heating element ground power and the signal wire work and a hack you can use to identify each wire. Using the knowledge in this video you’ll be able to diagnose and fix problems with oxygen sensors with one, two, three or four wires.

So I shot this video, edited it for a few hours than realized I misspelled signal on the whiteboard hahah wt..
Hi, my car kia stonic 2018 1.6 crdi had new dpf,turbo,egr,intake manifold and o2 sensors, and it's still running rich , showing 0.9v at idle and when cruising at constant speed stays at 0.4-0.5v, when giving it throttle it goes down to 0.1-0.2 , when releasing the gas pedal goes as high as 1.4v , running i guess as it regenerates the dpf every 130 miles and has a thin layer of soot inside exhaust tailpipe. Any suggestion what could be wrong with it, kia don't seem to know what's wrong with it .
Thank you
Not throwing any codes.
Lmao. This video is so old but I love your videos as well. That running for president joke is still valid and at the great advice you give in your videos… I mean at this point it must be a walk up and apply type of thing
Easy peasy boobie squeezy
Keep your political ambitions out of your repair videos and they would be grate . Like to learn what others have but don’t give a rats ass about your political views
I’m an autozoner and had wondered why my customer had two different o2 sensors. One had the correct plug that matches what he needed but the down stream had a different plug by the end of of the o2 sensor. Upstream had a square looking plug in while the down stream had a triangle look. He says it won’t match his vehicle but I tried the best I can to match his vehicle. Are the down stream and up stream o2 sensors supposed to look different?
Great Video
This is southern dipper. Can you, or anybody give me an answer on the question I ask about my 2010 Nissan altima 2.5 loosing power. Since I posted the question, I had all 4 spark plugs replaced, all 4 coil pks replaced, and changed the air filter. It is running better, but still at 3000, 3200 RPM'S, it is still doing the same thing. PLEZ, CAN ANY1 TELL ME WHAT ELSE I NEED TO TRY
How an where on sister on a 2004 grand am😊😮🎉
I wish you live near me. I have brought everything for my car. 2012 Chevy Cruze 1.8 LS. And it's still takes 7 or 8 Times to star. Help me please
I replaced both 02 sensors 2 times on my 2.0l honda crv yr 2000 still getCEL for heating element circut code for both b1 and b2 I don't know what the problem could be? Cat is in alittle rough shape could that be causing this?
0:02 it’s pronounced oxygen sensors not autism sensors

Does the power to the heating element, let's say for a 2005 Dodge Grand Caravan, shut off after it is warmed up enough? Because, if it does not, and the heating element portion of the O2sensor is bad, theoretically could one substitute the proper value resistor (and proper wattage power resistor) if the O2 sensor is a bear to remove? This of course just temporarily to get it to pass inspection until you have time to replace it and don't want to lay on the cold, snowy ground to do it.
Nice video.
However, I have a ford focus 2000 model ,but my downstream sensor has no single wire connected to it. It seems the wires were forcefully pulled.. the wires are completely damaged and missing. Please it is possible to rewire it,especially getting that signal wire that goes to the car's computer. Thanks
Brilliant video
I just tested my o2 sensor. When testing the resistance, I get an erratic reading. From 6 ohm to 100ohm. Does that mean my sensor is bad?
Is it true you can delete the sensors and the other sensors will step up
Do you have any knowledge on why my 2010 Nissan altima 2.5 is idling smooth, runs smooth, till i get on an upward hill on the hwy, it gets around 3000 rpms, and it starts loosing power so bad, alot of differant codes pop up, i get off the road, turn engine of, then restart it, it clears all codes, its in the shop now, they said it needed new timing chain, that didnt fix it. Muffler shop said converter was good, i had new maf sensor put on it also. Nothing is working i have had done. I need HELP😢
Nice video !! just wondering what is the signal wire for? with explantion please … thanks
How do I know which plug I need to plug into when all of my sensors (4 sensors with 4 wires upstream bank 1 bank 2, and downstream bank 1 and 2.)have the same fit on my 98 mercury mountaineer 5.0l ?
Great videos. No extra bullshit talk.
And how about the measurements on 6 pins ?
Does anyone if I can wire a single wire o2 sensor if my card original o2 is a four wire. And if so how do I wire that. Can I just cap off the heating wires?
Very professional experience! You taught me something I didn't know today. Thank you, sir
sir Chevrolet spark 2013 model oxygen sensor bank 1 and bank 2 sensor are same or not ? actually bank2 sensor not working but ihave extra bank1 sensor so can i fix the bank1 sensor place to bank2
Good watch made things simple
I am a diagnostic vehicle tech and loved your simplicity
WOW
`THANX
how do we change oxygen censor in Honda Insight Hybrid?? Labor cost is too much…
Nvm the videos I just found him and he’s too funny bruh.
Thank you brother you just showed me how to fix my wiring an it worked perfectly!!
I'd vote for you!
Doesn't modern obll tools test o2 sensor voltage?
Awesome videos very helpful! So I’m in the same pickle, my 4pin o2 wire harness is toasted and melted on the vehicle side. My question is the signal wire is a shielded wire, how do I complete the circuit with incorporating shielding in the 4 pin configuration
Watching your great videos from qatar. Qu, if test light is on battery positive and touch the harness side positive pin, what will happen?
The 2 white wires, and sometines 2 black wires are the heater wires.

You are funny and informative
So you identified the wires, how does this determine a faulty sensor or harness? If the heating element was bad in the sensor what would be the ohms?
Super
Thank you for all that you do and keep up the great work and stay positive as you are
Hey buddy great video I've been a mechanic most of my life but I've always been intimidated by the electronical
Hey I need some help what if I don’t get any voltage when I’m on the ground side touching the wires from the engine wires
AWESOME VIDEO, Thanks for posting this , very valuable , keep up the great work, Bless 😇
Is that a Steven Sigal sensor on the board?
Hi I have Prius 2007 and I the triangle is on with the can read P0136 ,P0AA6 y change the sensor 2 time and keep the triangle light
By running your testlight into the o2 sensor plug with 12v+ are you not risking damage to the computer?? The signal wire from the 02 sensor to the computer only puts out max 1v. I'm guessing this is a good way to cook the computer.
