Come along with Eric O. at the SMA shop as we have a look at this 2000 Toyota 4runner 3.4 4x4 that came in with the service engine soon light on and a P0136 O2 Sensor Circuit Malfunction Bank 1 Sensor 2 stored in the memory. We take a minute to run some quick tests to verify the problem and run a drive cycle after the repair is made to confirm the fix. -Enjoy!!

    Very good video I just did the bank 2 sencer 1 heater circuit malfunction it stopped work on my 1998 Toyota Camry V6 3.0,, same thing happened to me I ordered one and had the right server box but when I opened it up it was the wrong one, I mean im no Mechanic but I had enough experience to catch that you know. So I went to the parts store and bought the right one and put it in and works pretty good job well done. But very good video as all the videos I seen that you put out my friend

    why was the driveshaft spinning on the rack ? Seems odd, leave it in neutral maybe ?
    edit: Just noticed after the install … It was a stick shift in neutral, that explains it !

    They must consider you Second Hand. Apparently they've never seen your work. GREAT ERICK!

    Man you are the best! Exactly what I was looking for. I do mechanic service for friends and family and your videos have been of tremendous help and guidance. Thank you sir.

    Are Denso o2 best for Toyota? Are they OEM?

  9. Avataaar/Circle Created with python_avatars Joseph Ace says:

    Hey guys I have a question about this code p0136. I replaced mine 2 times and the code continues to coma back after 2 miles of driving, I hooked up my
    Scanner and was watching the live data. There is no power to it it shows zero voltage any one els come across this???

    It sucks when it happens because it’s time lost. I feel for you because it happened to myself many times

  11. Avataaar/Circle Created with python_avatars Matt Man Productions says:

    I'm so glad that Mrs O is getting better around the camera

  12. Avataaar/Circle Created with python_avatars David Nguyen says:

    Come on Eric, give Mrs. O a hand with those boxes.

    Helpful

  14. Avataaar/Circle Created with python_avatars medrano Lopez says:

    Nice idea

  15. Avataaar/Circle Created with python_avatars John Villas says:

    is that the upstream sensor located before the catalytic converter or after. i have the same code on my 99 4runner 3.4L sr5

  16. Avataaar/Circle Created with python_avatars Donald Ellett says:

    1998 chevy s10 – both of mine are welded on – have to buy a new converter

  17. Avataaar/Circle Created with python_avatars Gabriel Ortiz says:

    I also have a 3.4 2000 4Runner with the need to change the rear oxygen sensor. Is it better to buy it OEM or is Denso ok?

  18. Avataaar/Circle Created with python_avatars KTC Garage says:

    Awesome video man

  19. Avataaar/Circle Created with python_avatars Super Vitz says:

    Question… Is it safe to ignore codes for the rear o2 for a while? I don't have the time to fix mine this month. Thanks for great content.

  20. Avataaar/Circle Created with python_avatars Eric S says:

    Eric, would that missing O2 test option be available on the Varis or another diagnostic tool?

  21. Avataaar/Circle Created with python_avatars mindofencryption says:

    Ok, this real experience!

  22. Avataaar/Circle Created with python_avatars Matthew Graham says:

    Eric….and Mrs 'O and some 'dodgy' rare earth magnets….'  Parental Guidance Advised….Merry Christmas to you all…

    Did you say you were doing a "frame" on a murano????

  25. Avataaar/Circle Created with python_avatars Pine Hollow Auto Diagnostics says:

    Love the close-up camera work on torching those nuts off. You are the torch master, Eric!

  26. Avataaar/Circle Created with python_avatars Toyota Ron says:

    Eric, at Toyota on these we use Techsteam to monitor O2 sensor data and it gives us real time input on impedance of the circuit and current to the heater, going from memory here (don't quote me!) cold impedance is like 21K ohms and decreases as it heats up so the ECU knows approximate temperature. So, if it does not see any impedance (unplugged) it sets that code. I didn't see those parameters on your scan tool?

  27. Avataaar/Circle Created with python_avatars Aristotle says:

    Wow. You get one Toyota a year to work on.

  28. Avataaar/Circle Created with python_avatars mrsemifixit says:

    There’s no risk to ecu damage by checking the signal wire with 12v?

  29. Avataaar/Circle Created with python_avatars Christine Hucklebridge says:

    I like the new electric ice pic. gives me an idea…

  30. Avataaar/Circle Created with python_avatars David Goldberg says:

    Learned some helpful tips, thanks!

  31. Avataaar/Circle Created with python_avatars J.G The Auto Tech says:

    Which would you rather get first, tap and die set or thread chaser set?

  32. Avataaar/Circle Created with python_avatars Scott B says:

    Hey! I get a p1130 but only when the headlights are on. Wtf. Could a weak electrical system cause this? No leaks, new sensors, ohmmeter reads happy. Weird. Seriously.

  33. Avataaar/Circle Created with python_avatars Echologged says:

    Ah, good to see a manual transmission 2000 4Runner! Sad that it’s so hard to find a vehicle with a manual transmission these days…especially trucks! anyway, good video as always! Hope you guys have a Merry Christmas and happy New Years!

  34. Avataaar/Circle Created with python_avatars Michael Nicholson says:

    Merry Christmas to you and family. I really like your channel and the things you share. You help me fix a better sandwich! Lol

    Dude, I wouldn't even know how to deal with rust. Tech from Florida

  36. Avataaar/Circle Created with python_avatars RandomRon says:

    Now that's one fancy test light 😉

  37. Avataaar/Circle Created with python_avatars CR2504life says:

    your a surgeon with that torch, ……….. us DIY'ers would've busted off the studs with a wrench and then cried lol

  38. Avataaar/Circle Created with python_avatars geoffrwelsh says:

    O. I still see that age Toyota all the time here. If you install the test light (turn signal bulb), on the heater circuit, clear the codes, and start the car, the light will come on within 30 seconds or so. Also, you missed a chance to use your Mastertech! It has the factory Toyota software on there for this age Toyota.

    Hey Eric ? have you ever changed the timing belt kit on a 2010 Dodge Charger AWD 3.5 litre?

  40. Avataaar/Circle Created with python_avatars Adam King says:

    I once had a vauxhall insignia (European Gm) that I was chasing a o2 heater sensor fault on. Couldn't get heater to work ie no control side. was about
    to call the box. Then I found that it was turned on when you opened the drivers door .
