- The video shows a CHECK ENGINE light with a P0031 DTC on TOYOTA YARIS 2010 with 1NR-FE engine . And it shows the engine live data if the heater circuit of the sensor is OPEN. Replacing the air/fuel ratio (lamda) or wide band sensor, fix the problem.

This video enlighten me more.
After more research I realised that toyota A/F sensor have 2 types and the resistance varies .
1. Resistance is 0.8 ohm to 1.4ohms
2. Resistance is 1.8phms to 3.4 ohms .
These sensors are not interchangeable.
Thanks so much
thanks for watching
OMG this video is well done!!! Excellent troubleshooting and diagnostic skills demonstrated here.
Thank You
Another great video to help people.
My yaris is 2000 but milage is low enough. Car is bit sick tho and has check engine light soni need to get fixing
Thanks
which app are you using to detect faults? and can you let me know what usb adaptor youre using to plug in? thanks
I used the Torque Pro app and for the usb port you can see in the description of my video where i bought my usb adaptor..
NICE VIDEO,HI DEAR IF THERE IS STILL RESISTANCE WITH THE OLD SENSOR WHAT WOULD U DO IN THAT CASE ? CLEANING THE SENSOR AND PUT IT BACK ?
if the two black wire has a resistance that with in spec, then the heater is still good..thanks for watching
Hi, thank you for the video! Is it a 22 mm O2 socket? Thanks again
thanks for watching..yes its a 22 mm socket
This is the only video I have ever seen in which the engine is exactly the same as mine. Which helps a lot.
Where did you get the service manual that you are using please? I have never found one , despite looking long and hard.
I have the link but you need pay to download a repair manual and wiring diagram..
@@jlsetnuper Happy to...I'll message you
@@jlsetnuper Er, can't find any contact details on your channel...am I not looking hard enough?
I'll send you the website..you just need to enter you VIN number of your car..
Is your car a Toyota?
which adapter u used? OBD-II or JDM? Can u share link
i used OBD 2 bluetooth scanner bought from ebay..just search it on ebay "Bluetooth Car Scanner ELM327 "
well done
thanks for watching
Excellent
thanks for the comment
Is that sensor the same as the oxegen sensor.
Im getting 4 codes on my 2000 yaris vvti
P0171
P0172
P0130
P0133
Was thinking could do that sensor change!?
Any ideas to try before that maybe?
Thanks for uploading the vids
Its look like your Oxygen sensor 1 (the upstream sensor before the catalytic converter) is faulty..try to check the wiring first on that sensor , if its ok then replace the oxygen sensor 1..
@@jlsetnuper ok. Sounds good thanks. I will try as you say👍
Can this cause dpf problems I don't have any codes for the sensor just dpf going round in circles had the dpf cleaned still same problem thanks also can too much oil cause dpf problems any help would be appreciated
oxygen sensor fault will not cause the dpf light to come on, but try to check the dpf pressure switch or dpf differential pressure switch maybe it is faulty?
where did you get cell phone stand for your car ? its at timestamp @0:21.
I bought it from IKEA..
@@jlsetnuper what's the apps call ?
@@benyblack4404 its a "Torque Pro" ..thanks for viewing
Good video but I have a problem. I have a code P2196 Oxygen (A/F) Sensor Signal Stuck Rich (Bank 1 Sensor 1) Do you think by replacing the sensor in the video will fix my problem. It’s same car Toyota Yaris 2009 Tr 1.33cc petrol. I’ve checked the wiring around the engine and it seems ok.?
EJ did you fix your problem?
I have same code in my car Yaris 2009, I changed the sensor, now I have different code p0031 !!!!
khaled guerfa I didn’t fix it I just kept clearing the code with a fault code reader. Will you tell me where you got the sensor from or send me link of the sensor because it need to fix it ASAP as it keeps on coming on.
khaled guerfa also for the new code it says online that it’s the oxygen sensor but it might be the sensor trying to adjust to its reading with the ecu when the engine reaches optimum temperature. Why don’t you try to take it for a good run get it to optimum temperature and see if the light goes off by itself. If not clear it with a fault code reader and see if it comes back on
I m working in Garage
I tested with emission tester , it was ok pass. But the funny story is I ordered the sensor from Toyota dealership and they sent me the wrong sensor.
@@khaledguerfa2948 thats strange how can they give you the wrong sensor. How did you figure out it was the wrong one. Does the part number on your sensors match old to the new one?
Can you kindly specify the colors of wires blue and white
blue and white wires are sensor signal wire to the ecu...
What is the pid for o2 sensor 1.. as it is not giving any reading in torque pro.
maybe your car is using an air/fuel ratio sensor (wideband sensor) for oxygen sensor 1..in the torque pro it is giving a reading on O2 Sensor1 wide-range Voltage.
@@jlsetnuper my car is honda civic 2012
It is giving comanded air fuel ratio reading and measered air fuel ratio but both are fluctuating...
My egr error is sometime negative and sometime 99.2
@@jlsetnuper my both fuel trims are about -17
@@mohsinrehman4246 air fuel ratio reading should not fluctuate, it will fluctuate momentarily when you rev up and back to steady..
@@mohsinrehman4246 there is a problem in your car, check for leaks, the air filter and the mass air flow sensor
Was that Bank 1 Sensor 1? Are you sure? Was that upstream?
Yes its upstream sensor...
@@jlsetnuper Is it bank 1 sensor 1?
@@user-wp3bd8xg3d there is no bank 2 on this engine..
what is the fault reader, can I download an app?
torque pro app
@@jlsetnuper thanks, did you put anti seize on the threads before installing?
@@chrissecc3913 yes
was the car working properly with the check engine light?
yes the car work properly with the light..but it affects gas mileage a bit
no loctite ? just asking.
I secure it with double sided tape
