Ph***:

Hello Chris, Do you have any video how to clean catalytic converter?

Ro**********:

Hey Chris, my name is Romario, I live in Brazil and I love to keep up their good work in the engineering and mechanics in relation to cars and other. I would ask you, if possible, for you enable subtitles in Portuguese in their videos as they do not fully understand English, for better understanding, I wish you enabled the legend in Portuguese! Thank you very much, I'll be happy to get a return to my message! God bless!

Mi****:

You've got some awesome videos, Chris. Great camera work, makes it easy to see everything. You've inspired me to do a lot more of my own work on my car, and I've saved a ton of money doing it. THANK YOU!

Ji*******:

Hey Chris, thanks for another informative video.  As is your pattern, your vid has some gems some might miss; like renting that specialty socket; a simple breaker bar extension for a socket handle, use of anti seize...

I would love a ChrisFix website or page.  You've helped me many times.

Oh, BTW, one day, while all of us know what your ARMS look like; one day you should show your face... 

Ju*********:

hey Chris thank you for the video gona get at in morning let u know the outcome.

Wa*********:

Amazing videos chris even though my car dosent have any of these problems yet i still watch them, thanks for making these videos.

Ra*********:

I changed the O2 sensor of a Suzuki Alto k10, I had to remove the exhaust manifold, it was very tight so we had to heat that sensor, then it came off

el*****:

Great video! I'd recommend to spray some WD-40 or PB Blaster to where the sensor threads with the engine off but still hot. It will loosen more the sensor. I had to replace this "Air/Fuel Ratio" sensor on my '05 Hyundai Elantra 3 years ago. It was around $165. I checked online on Advance Auto Parts, and found a promo code that took off $50. It was still expensive paying $115 for a air/fuel sensor, but cheaper than paying $165 + tax.

Ju*********:

Hey Chris I just replaced the O2 sensor in my 07 Infiniti m35 and went to start it up and the code came back with some misfires any ideas on what I can do? Thank you

Ri*********:

Thank you I learned how to trouble shoot the 02 sensor thanks to your video keep up the good work

Mi***********:

it's always a freaking sensor.

To********:

One of the better channels as regards camera techniques and presentation.Very clear diction and makes the
viewer feel that he is part of the action.Plenty of resources supplied and a willing attitude to share wisdom.12 out of 10.

St***:

Google search brought me here... As soon as I heard "hey guys, Chris fix here"... That's when I knew I'd learn how to fix this!! Thank you!!

Am*********:

Q. How do you know that is "bank2/sensor1".

Me*********:

I was always told that the downstream sensor does not affect fuel trims or mileage and that is Not true!  The first purpose of the downstream 02 sensor is to measure cat efficiency. The second function is downstream fuel control. This function adjusts the upstream 02  goal  voltage within the range of operation of the upstream sensor. The upstream goal voltage is used to ensure long cat life by allowing the PCM to control the amount of air and fuel that is supplied to the cat. If the downstream 02 sensor switch point is at a  low voltage the PCM will adjust the upstream 02 goal voltage to reduce  high 02 content by . If the downstream 02 sensor  switch points stays  high, the  upstream 02 sensor goal  voltage will change and  allow a low 02 content.
My fuel trims were in the negative 25 percent until I change my fixed rich downstream sensor.

Ri***********:

How about a single wire O2 sensor.

Ni******:

One tip I read is that you should do this kind of work on a cold engine (spark plugs or sensors) because metal contracts and shifts when hot. (Not saying you over tightened, just wanted to share that, also I am sure the anti-seize will prevent any issues).

Ma*********:

Hello Chris, thanks for your videos..i have a question, do you need to disconnect the battery to do this job?

It*******:

OH SNAP CRIS IS STILL REPLYING TO VIDEOS 5 YEARS LATER
P.s. I’m not even old enough to drive legally and I just love watching your videos

El*********:

man that was an amazing video, thanks for helping me out i just did mine n it work's just fine

D3*******:

I swear every problem I have in my car Chris has a video for it. He is a dictionary of car problems thank you Man!!!

Pa*************:

You're the BEST Chris! Thanks for your consistent, high quality videos. Never lets ya down! Thank YOU!

Ma***************:

when are you going to change a bad catalytic converter?

re**********:

Wow, clear and to the point, great camera shot and the testing of the O2 sensor, was very clear and the selection on the amp meter to where the right setting , must video they just tease you. thank you, sir,
You might also check the elbow grease and test the blinker fluid .

Jo*******:

Be**************:

I tested my o2 sensor and it reads 5.1 ohms is that a good reading

Sa****:

 @ChrisFix  I can't wait till you post the seafoam for a car test!

jo*************:

a trick you could use if your in a tight situation and don't have a braker or cheater bar is getting a deep socket that fits around you ratchet and extention

Am*********:

Can’t you just remove that heat shield and use a wrench to remove/install it?

Da***********:

This man 10 mins of driving and your gas stays the Same place ??

At********:

Chris: A special socket is used to remove oxygen sensors
Me: What if I take a socket of same size and make a slot in it?

Au***********:

+1 for showing how to test the old sensor!

Mr*:

Short and sweet.....straight to the point

Mi********:

very helpful Chris. I have to change mine this week. CEL comes on and Porsche 911 diagnosed the oxygen sensor ahead of cat 46. Plus a knock sensor and a below par fuel filler shut off valve. I was quoted $1200. I bought the gear which I needed for all 3 jobs plus tools for $400. A saving of $800 as I am a DIY guy. Porsche have special very costly durametric testers for their vehicles.

ro***********:

THANK YOU!! This video helped me get rid of my check engine light and helped me pass the smog check!! And I saved big MULaHs!!! I even got the same multimeter and same O2 brand as yours. The only thing missing here are more details on how to complete the driving cycle so the OBD2 can read the catalictic monitor after replacing the O2 sensor. It took me a while but I found out that Toyotas require a very specific driving cycle:
first, drive at 45-55 mph for 7 minutes, then, drive at 35-45 for another 7 min. Speeds must be consistent and non-stop. 
For those of us who do not pass the smog check due to Catalytic monitor "not ready" or "incomplete", this driving cycle would do the trick. It did it for my Toyota Camry CE 2000. THANK YOU AGAIN!!

Me*********:

The wave of the 02 seems secondary to another issue in many cases.  Like an EKG reveals an irregular heartbeat, the O2 sensor waveform will also reveal any underlying problems such as vacuum leaks, ignition misfire, injector imbalance and even compression losses. Each of these conditions will produce a characteristic type of hash in the sensor waveform. Anytime a cylinder misfires or leaks compression, unburned oxygen enters the exhaust. This shows up as a momentary dip in the O2 sensor's output voltage. So if the O2 sensor's waveform contains lots of little inverted spikes, it tells you the engine is misfiring or leaking compression. You can then use your other diagnostic equipment to nail down what is causing the problem. A "digital storage oscilloscope" (DSO), also known as a "dual trace scope," is unquestionably one of the most useful pieces of diagnostic equipment that is available today and prices for under 100 dollars for a basic bare bones model.  This could help answer "is it cause or effect" type of questions underlying this and many other theories in the field.

Da************:

It helps to have the engine a little warm, the exhaust will be hot enough to make it easier to break the sensor loose. If the sensor is confirmed to be bad/dead, don't bother with the special socket to remove the bad sensor, just cut the wires and use a regular socket to remove it. But, a socket with the slot is needed to put the new sensor in. Never use dielectric grease in the connector, the O2 sensor gets reference air thru the wiring, the grease will block the air from wicking down the wires to the sensor, effectively rendering the sensor bad. The sensors have an air cavity in the body to sample outside air to use as a reference of oxygen content. The sensor uses the reference to send a signal to the pcm of the oxygen content of the exhaust. For those interested, Wells Vehicle Electronics has a video on their youtube channel that explains all about the narrow band O2 sensors. It's a long video, but it is very interesting and educational. Btw, i'm a Chrysler dealer tech.
