Great diagnosis Dale . You sure are teaching Sasha a lot and the cool thing in my book is that she shows a lot of interest . I have been trying to catch you live on Wednesday's but I have had a lot of doctors appointments on that day . I have about six more weeks of injections then I will be able to catch you all live again. Have a great weekend and be safe .

thats one really nice thing about a off road vehicle you dont need tp jack it up to work on most things

Dude!
There is a good reason you have almost a million views. Someone...you, finally showed (as Paul Harvey would say) the rest of the story on testing the O2 sensor.
Thanks for that.

This is an excellent demonstration of how to properly test the sensors works on almost every vehicle. I needed it because I am having troubles with my Toyota Camry and all indications from the OBDII lead me to the downstream sensor which is an unpleasant thing to reach. Looks like I can now at least test it before dealing with an unpleasantly hot exhaust system that needs to be dropped in order to remove said sensor. Thank you for a nice and concise video.

One of the most common codes... Great video. You are a damn good teacher.

Man I absolutely miss my 97 Cherokee County! It had the strongest 6-cylinder engine I have ever driven! Torque for days! I'll have to say that was the most reliable vehicle I ever owned! Bought it used and paid $7000 for it in 2000 and drove it till 2017 and she never left me stranded! I'd trade my 2011 Sierra Texas Edition for your blue Cherokee!

Hey my guy thank you so much it worked perfect for my problem is good to have this much detail when due you sellers are trying to fix their own problems 💯👍👍👍👍

just a note, the second oxygen sensor is not the one controlling the mixture for the ECU, its function is only to see that the signal when compared to the front sensor ist flat meaning the cat is functioning. The front sensor is used to test for air/fuel ratio and tell the ECU what mixture adjustment is required. So your faultcode could only come from the upstream (front) sensor. Downstream would cause a „Cat inefficient“ code on the motor warning.
have fun, Bernhard

Grest instructions. Easy to see what you are doing. Appreciate your time!!!

[devinrogers]

Thanks for taking the time to post this 👍

[andrewroberts]

Awesome! Even though I get a code on what O2 sensor to change, now I know how to use a meter to verify before swapping it out.

[mariobueno]

Excellent way to describe the process and why it's not working.

[drwisdom]

I found this video to be informative and a good presentation.

[jesusaguilar]

Simple, clear, and to the point. Thank you.

[victoryfirst]

Now I can check my own O2 sensor and verify if it is faulty. Thanks for the information.

[julianrosalesniles]

My OBD2 Scanner said that I needed to replace the upstream oxygen sensor. I had already bought a new oxygen sensor prior to watching this lol so I was scared I bought it for nothing but I still have the receipts just in case I want to return it..
I did what you did in this video and turns out that I need a new oxygen sensor after all 😆

[tunafish]

I’ve seen people bench test them using a propane torch with out running the vehicle and it works great.

Thanks this was most informative and easy to follow visually. I’m going to try it now
