    You know your winning when a mechanic can’t pop the hood on your Tacoma! 😆😆😆😆😆😆

    Notice he's not very good at opening Toyota hoods? He can open s Chevy hood blind folded.

    When u say use a test light.. does it matter what kinda test light does the bulb in side matter? .. and what the reason for using the test light and not v meter?

    Replacing O2 sensors we always used the dealer O2 sensor new is there made better

    Great vid. I drive a 2003 Tacoma, and just dealt with the O2 sensors. The studs and nuts were rusted bad on mine (I live in the rust belt of Eastern Canada) but by some miracle and a wire brush I got them cleaned up enough for the new sensors. When it looked bad for the studs, I did a quick surf on youtube to see if anyone had found a solution for this in case I wrecked a stud, and I found a video of this guy doing the sensors on a Sienna mini van. He took the existing studs out with heat and vise grips, and just used bolts for the sensors- seems to me a better solution, since there is no exposed thread to rust away, the bolts are inside the flange. I didn't go this route, since I salvaged my studs, but would probably if I had to replace an exhaust piece that had a sensor flange in it. One of the few careless engineering flaws I've found in these trucks (I've had 3 of them) besides the bad frame issues.

    Yep the real brain buster was the chevy with the fuel pump driver issues the bad wire lol

    Thanks alot man u really helped

    I had a 2000 Tacoma which threw up a rear O2 sensor. Truck had no get up and go. 30 MPG was the only good thing, after fix dropped back down to 15 MPG, but full power again. The problem was a dirty mass air sensor.

  11. Avataaar/Circle Created with python_avatars Michael says:

    Great video.

  12. Avataaar/Circle Created with python_avatars Yumpin Yiminy says:

    That's way to long to have the RPMs settle down to around 700.

  13. Avataaar/Circle Created with python_avatars Yumpin Yiminy says:

    Toyota's '01 exhaust O2 sensors where a weak spot. The only part I had to replace in 13 years other than regular maintenance was my front exhaust oxygen sensor. The wire was part of the sensor so you need a socket with a small slit in it and a very hot engine to remove it.

    My current Toyota has had an occasional tip in hesitation since I bought it new. Maybe 3 or 4 times a month it will do that. I got used to it and figured there is no way I would ever find it. Other than that it's the best vehicle I've ever owned with 145K on it.

    Your deductive reasoning paid off here. Good job Eric. Glad to see you are not a beer guzzling, cigarette hanging out of the corner of your mouth, dirty clothes that needed washing 3 months ago, untied shoe laces, garbage cans overflowing, windows never ever been cleaned, doom and gloom explanation of the repair and how much work is involved and that's why the price is 4 times what any honest shop will quote you !!! SMA is the needle in the hay stack, lots of hay shops like what I just described …… when you find the needle shop (SMA) you know you won the NY lottery of great service, fair price, just the facts ma'am, quality parts [ Dorman :- ) ] and someone who stands behind their work !!!!! And I certainly hope you have Keurig coffee or cold water for your customers, along with a SMA souvenir !!!! You and SMA are surely a pillar of the Avoca town !!! PS Check up on Vinny !!!!

    I have a 2000 Toyota sienna 6 cylinder 3.0 I have 2 oxygen sensors

  18. Avataaar/Circle Created with python_avatars RCWorks says:

    All O2 senors are the same unless they are air fuel ration sensor,,, Then they are indeed different.

    My 06 Subaru does this. When I take off from a stop, she bucks a couple times and then takes off.

  20. Avataaar/Circle Created with python_avatars robert black says:

    Dag nabbit!

    Watched a million of your vids waiting for a Tacoma …and this one is a 2001 (mine is a 2013). Doesn't Mrs. O, or Hannah or Marie or Josh need a second genTacoma?
    You hardly ever work on Toyo trucks…wonder why that is?

  21. Avataaar/Circle Created with python_avatars davecc0000 says:

    I remember you saying to never use a test light on a computer input. But then I’ve seen you do sensor signal simulations like this one.

    When is it not OK to use a test light on computer wires?

    Thanks.

  26. Avataaar/Circle Created with python_avatars Brandon Knight says:

    Our 99 3.4 Toyota 4runner runs worse after using a can of seafoam, 1/4 through the Pcv hose and poured the rest in the gas tank, now sounds like it's missing 2 cylinders until you throttle the engine up to about 3,000 RPMS then it mostly smooths out?

    Your videos are second to no one. Very informative video. I really appreciate how you explain your thought process. Thank you for spending the time.

    That was some cat like reflexes with that drop light eric👍

  29. Avataaar/Circle Created with python_avatars george gonzalez says:

    You could make a nice test fixture by taking the bad O2 sensor connector and wires and putting a small 12 Volt taillight on the heater wires. That will be a nice load and foolproof telltale whether the heater circuit is live. Do that twenty times and you'll have enough test fixtures to cover maybe half the cars!

  31. Avataaar/Circle Created with python_avatars Duncan Mac says:

    Thanks for the video.

  32. Avataaar/Circle Created with python_avatars John Ferguson says:

    Come one, Eric. Use some stainless steel nuts on the O2 sensor. Keep it sealed up for safety reasons; don't want CO2 leaking into the vehicle.

  33. Avataaar/Circle Created with python_avatars Freddy Flintstoned says:

    My 99 4Runner 3.4l has an intermittent CEL. I was told it is an O2 sensor. The engine runs fine when the light is on or off.

  34. Avataaar/Circle Created with python_avatars Jerimiah Reece says:

    Learning good stuff here!

    Question for you though. I've got a 2015 Tacoma V6 that's used for offroad. The truck had 4 cats on it originally. The front two cats were removed after installing long tube headers. This causes a permanent check engine light as the rear set of 02 Sensors don't get the read they expect without those cats. Can this impact fuel economy? What I'm seeing online suggests the post-cat 02 Sensors only trigger the Check Engine Light and don't impact fuel trims, etc. That true in your experience?

  35. Avataaar/Circle Created with python_avatars Edgar Bravo says:

    I got a 1997 toyota camry 2.2 throwing a p0136.. There is a separation from the down tube to the flex pipe. I didn't throw any O2 codes until the pipe started to break.
    Holes in the exhaust system can throw p0136 and just fix the hole and it goes away.

    Do you source those push mount wire ties locally or do you go through Amazon?

    Hi Eric o I see you have a 18 volt m18 Milwaukee wrench how do you like it

  41. Avataaar/Circle Created with python_avatars Kieran says:

    Excuse me for being dumb, how on other three wire sensors where the bypass tests can be done when unplugged the voltage on the scan tool shows 5v but when on o2 sensors when unplugged goes to 0v
    Just trying to learn things thanks

  42. Avataaar/Circle Created with python_avatars Moggie20170000 says:

    yes the truck's got a stick in its tail pipe. that's why its cranky.

  43. Avataaar/Circle Created with python_avatars Andrew says:

    What kind of zip ties are those?

  44. Avataaar/Circle Created with python_avatars Bob Rossi says:

    Eric…need your advise. I have an 08 Honda FIT with 160K on her. This summer the A/C has gone wonky and nobody can figure it out. ONLY on oppressive humid days does the A/C blow hot air. The clutch is engaged while this is happening, and the R134A level is fine, as are the Low and high side pressures. Once the humidity goes down, the A/C works wonderful again. What would cause the A/C to blow hot air ONLY when the humidity is oppressive? Thanks much for any advise on this.

    Can you please help me with the code of a Toyota Tacoma p141 of the check engine
