For all wanting to find out what wire is the signal ground you need to start up the car and look for voltage between it and the positive side of battery.
La resistencia puede ser ser de 1M ohm 1/2 watt, y el capacitor de 1uf 50v segun entiendo (no se porque pero en unos paises cambia el color de la resistencia 😢)
I would like to ask question to understand about hit sensors? show 2.7.dis is ok or mast be different numbers of sensor ? And I have bank 1sensor voltage 3.266 to understand where do I have to connect dis resistor? If you can give me eany information about please 🙏 thanks Eand I have bank 1 equivalence ratio is 0.996 .to understand where is mast be connect dıs resistens ? Thanks 🙏👍
Sir i have Hyundai accent 2013 mode i remove the oxygen sensor connector but there is no check light in dashboard meter why this not showing on dishbord meter please,?
2005 Jeep Wrangler 4.0 all 4 sensors testing low on heater code P0031 - P0037-p0051-p0057 I replaced all with NGK and still lit on. I checked all the wires, disconnected the PCM, and continuity was all good, Pin 1-3-4 were good from the sensor to PCM plug and pin 2 to ground, what else?? Thank youi
Either the sensor itself is bad or the harness is not gripping well. H2OS code p0031 is related to heater cicuit reading low, check the pins or the wires
If the harness, the pins, wires have been checked and are ok, or if you have replaced the sensors with new ones, i will suggest you to recheck the continuity of the sensors, not matching the desired or required by the ecm
So if someone cut my cat's out I'm in a state where I don't need them to register the car so if we do this we don't need the downstream sensor at all do we?
if you live specifically in the northeastern states, they are trained to spot devices attached to the vehicle such as these. they know what they are doing and will fail you . i hate the northeast , over here , you will 100 percent fail emissions just for a check engine light on, even if its not related to emissions. just the light being on will be a fail.
would this work for a p0137(low voltage from rear o2)? the sensor is the correct one and good but since i installed headers its been setting it as a nuisance code
Bravo - you outsmart the sensor, the control unit recognizes it as OK. It just can't regulate it, your ECU always gets the same input. As a result, the car never runs properly. BUT - you will no longer receive an error message!! Your crafting is total nonsense!

This is verry halpfull to me menny thanks to you keep them vidios going kind regards to you
Very good video ...when you d0 this bypass do you ever get a heater code for high circuit on heater when your heatwr circuit is good

Please Can you right the exact value of the resistor and the capacitor ?
Thank you a lot for your video.

@@autohacker1137 you said 4,84 Kohm in the vidéo.
That was an example, please listen to audio, i have said that use 1 ohm
@@autohacker1137 Ok. 👍
How to know the proper ohm to use for the O2 sensor? anyway to check that? thx

Hi, can I use this method for my van? My van is showing engine light and it is saying sensor is not good.

Are all o2 sensors the same resistance

You can leave it but the ECM will be mad and the money light will stay on
And us there away go get read off the light
if you live specifically in the northeastern states, they are trained to spot devices attached to the vehicle such as these. they know what they are doing and will fail you . i hate the northeast , over here , you will 100 percent fail
emissions just for a check engine light on, even if its not related to emissions.
just the light being on will be a fail.

can I do both just to get rid the check engine after catalytic converter delete?
Actually heater wires don't make sound when you test it by multimeter and 2 wires have the resistance between 3-10 ohm.
The blue color is a signal rite & white is a eart?

I think i have mentioned that in the video, kindly no need to be over smart here. Thanks Mr, perfect
Can it work for upstream oxygen sensor?
02. Only
@@autohacker1137 Is it the first sensor or the second sensor?
Or both?
Second
It’s give me po606 ecu code what should I do

Neechay walay oxygen senor mein adopter lagwa lo aur computer reset karwao set ho jaegi, P0420 catalytic aur o2 sensors related issue hai.
going to try this on my downstream sensors after cat delete
Did it work for you?
@@jeremygugelmeyer4586 yes
@@DanKirchner5150 did you attach the two of the heat circuit? still working?
At 4 min 10 seconds you comment that we will need to have a 1 OHM resister then you install a 500 OHM resister ??????? in the heater line ?????????
He adds 2 one ohm resistor in parallel
Cannot hear you or understand you
1 ohm is to small
Easiest way to bypass is to raise Ox sensor via additional bolts on top where it will sense nothing basically.....
if it senses nothing (no oxygen in exhaust), cel will light up.
@@slec-wz1dbno it will not.....
Also to add, if you shake the sensor close to your ear, and you can hear a rattle...the element inside is burnt..no need to test.
I can't understand a damn thing you're saying
