Thank you, Found AF Fuse Missing! 10A Fuse was slotted into the Blank Spare slot and the AF Slot open. Masive waste of my time. Now solved thanks to your video.
Great video I was about to order 2 new sensors, and it dawned on me 2 sensors gone bad at the same time is a bit odd...didn't think about the relay! Thank you!!
If you are working on a Toyota, be sure to read the part number on the old sensor , before you buy a new one. You can find part cross over refences, on the Internet. Denso makes the OEM Part. This can save you both Money and headaches.
Hello, I am Veysel, my car is 2015 Toyota corolla P0031 fault code, there is an attachment in the cable, I think the sensor did not fit and they added the cable, is it possible that is the problem?
2009 Camry got codes poo31 and poo51. It says I need Low Bank 1 sensor 1 and Low Bank 2 sensor 1. So after some research heres what I found. Check how many o2 sensors your vehicles actually has. There's two UPSTREAM an two DOWNSTREAM. Toyota recommends you replace both at the same time. Now when I had the computer at the auto parts store run it said Heater Oxygen Sensor Heater Control Circuit Low Bank 1 sensor 1 (poo31) and Heater Oxygen Sensor Heater Control Circuit Low Bank 1 sensor 2. LOW BANK means UPSTREAM. The guy at the auto parts store said if its downstream it will just say something like BANK SENSOR or something like that. Anyway, so of course I started checking online for parts lol they werent priced bad at all. Then I start reading reviews and people are like "Don't buy this junk" etc etc. Apparently, you only want to buy genuine Toyota sensors. DENSO makes Toyota sensors. DENSO is what i can buy at my local parts store. The guy at the store started laughing because i ran over to return one I had already bought and hes like "Look it up Toyota owns Denso" lol its the truth lol anyway, I bought the two sensors but my mechanic keeps saying try the relay so i guess we will. I know my check engine light is on and my car is getting hot too quick. Its not going over half but its faster than it should. I let yall know what happens hope this helps anyone looking for info
I guess I’m a little confused about what problem I’m having. Started out with a bank 2 sensor 1 heater control circuit low decided to replace it and also decided to replace bank 1 sensor 1 also because it came with two new sensors now there’s a code for both bank 2 sensor 1 and bank 1 sensor 1 heater control circuit low. We have replaced the A/F heater relay also still no change.
@tyler lag Did you ever figure it out, almost same exact scenario with me. Bank 1 sensor 1 replaced due to p0031 and after replacing it both p0031 and 51
@@mikeolortegui260 as it turns out, my second downstream AF sensor failed right after installing the new one. The new one ended up being DOA. It was just an unlucky series of events that made troubleshooting difficult. My solution was an additional 2 sensors from Toyota
@@scottybeall I'm geting p0038 p0044 p0143 can you look these up please and tell me what you think iv tryed few things so far no luck I did buy aftermarket sensors from orally autoparts right when I installed them earsed code came right back in a sec any other solution for this thanks bud
OH HELL YEAH!!! This just saved me over $100! 🤘

Thanks for sharing. This tutorial really works.
You are life saver thanks for the great video
Im glad it helped you..

Good idea 💡!
Thanks for the heads up
Outstanding! Now what is the other relay for?
Saved me so much cash dude! Like I almost went out and bought new sensors everywhere
Glad to hear my video help you...
It took the whole day for the check engine light to come on again. I changed the o2 too
Good job bro
Thank you my friend.
what is the 2 bank 2 sensor relay of a tundra 5.7
I have the 0051 code on my 06 V6 Camry. I'm gonna check that relay. I'm sure they're cheaper than the 02 sensor
did it work
Wondering too if was your relays , wires or the 02 sensors?
In TOYOTA corolla verso 2.2 d4d 2005, where is this relay located because I have the same error code P0031?
Thank you, thank you..
Thanks
I have a Circuit high you have a circuit low is the problem the same? 2008 Prius
No, you may have too much fuel, or your catalytic may not be working properly.
@@avpautomotive6337what can be the cause of too much fuel? 02 sensors or injectors or both possibilities?

Did it come like that from Toyota? Or dies it look like somebody cut and reattach the wires?
I got a bunch of sensors that just started to fail for no reason. Maybe i have bad fuses ?!?
You have to check if they all share the same fuse.
@@avpautomotive6337 Probably. haven't had time, broke my leg today XD!

مافهمت شي
لاتفهم احسن لان كل ريليه عنده رقم معين في ال ecu واذا غيرت مكانهم عادي الecu يصير فيه short circuit
