Peter Congrats on 80 k. Your a Toyota whisperer. Japanese quality is #1

[@rightlanehog3151]

Peter, 80,000 Toyota Maintenance Subscribers Can't Be Wrong® Well done! We think We better have this Sienna back in the shop so We can change some of those 20 year old fluids ;-)

[@dalepremo3695]

Another clean, professional and caring repair.

@Toyota Maintenance. Thank you Professor Peter for today's lesson. Also, congratulations on 80K subscribers. Hope you and your family stay safe and well.

[@michaelbrennan7148]

Thank you Peter. Good stuff with multi meter. Wish that stuff was introduced in school curriculum (Thank goodness for spell check) Very helpful.

Always a good day when a Toyota Maintenance video drops :)

Such a beautiful model engine, 1MZ-FE. So unbelievably new. Like a unicorn. You never see it. I remember changing the rear spark plugs. But in a sedan. Less room, but you could still do it without removing intake. Stubby ratchet and two short extensions. The one close to the PCV on the passenger side was easy. And the other two were relatively not so bad.

[@physicskid]

Thank you for taking us through your repair job.

[@tomfilbey]

That's a clean engine! Replacing the bank 2 sensor is a piece of cake compared to the bank 1 sensor.

[@brolovelace1486]

You saved me hundreds of Dollars.. Thank you very much!!

[@southernfarmtech]

Absolute integrity. Love watching your repair videos. If you ever leave California, come to Alabama...I will trust you with my 2001 Lexus ES300 implicitly. :-).

[@LAactor]

The engine in this video is your same engine!

[@WallaceRoseVincent]

Peter, heat up the engine and make an egg burrito on it! It's so clean!

[@bytornsnowdog1347]

Great instruction video. I was not aware of the A/F fuse. Many thanks!

[@eugenesimmons8554]

Love these videos. California cars are so clean. You should come to the northeast and work on salted cars. You won’t find old cars like this so clean.

[@YOumeanMe]

yea i gave up on oxy sensor bank2 on corolla.. difficult at best to get at..and didn't solve the problem.. black electric tape did on the dash helped me forget about it and it runs fine. congrats.. Your intro is spectacular.. felt like i never left.. i'm leaving now.. next time

[@gam85191]

Good work my friend. You are a Toyota expert

congrats on 80k subs. your amamzing

[@cjpamp1267]

Great to watch you and Scotty Kilmer now I know my next car will be a Toyota

[@mscir]

Thanks for showing us the copper based anti-seize, I never used that but will in future.

[@mckoylach1622]

Thanks for the video. Question regarding,whether the part is OEM or not,how do you identify it ? Is there a unique or significant design of the O2 sensor,that will say it’s an OEM ? Because any O2 sensor manufacturer can label it “Denso”

[@spauldingalbert]

Love Watching your channel there is always something interesting to learn.

Congrats on 80,000 subscribers! You deserve it, such an awesome channel.

41,000 Miles ! That thing is still under Warranty !! , especially if she's the Original Owner. The next proper step is to implement the one paragraph "OBD 2 Drive Cycle Test because all the OBD 2 Monitors were "Set To Not Ready" whenever we change a Battery or Turn a Check Engine Light Off. If ANY Vehicle is a 1996 & Newer vehicle & she has a Smog Check Appointment the same day or the next day, she'll & everybodys vehicle will FAIL the Smog Inspection if the OBD 2 Drive Cycle Test wasn't performed.

[@davidg5704]

I only buy Denso O2 sensors even though its expensive. Mush better quality. bought cheaper ones in past and they don't last. Is it ok to use dielectric grease on connector to prevent moisture and corrosion of contacts?

[@nickv4073]

yes

[@SeanPopify]

No, no, no! Dielectric grease is not conducive! Don't let it touch the contact terminals! You can surround the connector, but do not interfere with the electrical connection itself! Same thing with spark plugs. Use a q-tip covered with dialectic grease to coat the rubber part of the coil, but do not let it come in contact with the electrical contact points. you want those little pieces of metal to be completely clean.

[@nickv4073]

@@SeanPopify Nonsense. You know what's worse than a near zero loss of conductivity? Green crusties on connectors. The man said nothing about smearing it on spark plug electrodes.

[@SeanPopify]

@@nickv4073 Dielectric grease is commonly misused on electrical connections of all kinds. Dielectric grease is commonly used on spark plugs, commonly *misused* on spark plugs. Since the topic is car repair, it's good to throw those helpful things in, for future reference. DG could be used to prevent water getting into the area where contact is made. Context and comprehension is important. This is especially so when 1/100th of a volt or ohm could make a computer miscalculate another operation elsewhere in the engine.

[@xelaju8]

Another awesome video. Thank you.

[@paulparoma]

Back in 2001, there was still a reasonable amount of room under the hood in most cars. Not so today.

[@Imagehype]

oh your in cali? nice. love your videos.

[@neillefebvre9494]

I have the same problem but the code won't clear . Change the relay and the fuse. Still comes back?

[@lonesomecricket7721]

Is there any difference in quality between the denso sensors from Toyota and those from other suppliers? Thank you.

[@georgemojica3111]

Very informative! Thank you.

Thank You very much sir .👍😊

[@roltyd22]

Have you ever heard of the af sensors causing pulsating headlights and dome lights?

[@plantfeeder6677]

Hello, here is my problem. I have a 2000 Toyota Sienna(California ed.). It runs good. Gets pretty decent mileage and burns a little oil but has intermittently been throw the code P1050 and very occasionally with P1030. I tried looking up the codes and found 1030 is the variable valve sensor but have not been able to find anything on 1050. I keep getting directed to P0150 which I'm positive it's not. The 1050 code I mostly get by itself but occassionally it'll be accompanied with the 1030. The battery is on it's last legs, could that be what's doing this? Anyway if you would please let me know what P1050 is so I can finally fix it and start my how long journey who the heck knows of resetting the monitors, I'd be very grateful. Thank you.

[@applesauce689]

Hey Peter what is the most common problem or reason that 3.4 5VZ-FE gives up? 🤔

[@Brettisgg]

around 500k miles the head gasket will start to go from most folks experience. otherwise, as long as you do basic maintenance no issues. If you have automatic transmission make sure to do the radiator fluid regularly to avoid the transmission cooler (inside radiator) from going and destroying the transmission.

[@brian242101]

is it bad that my car is missing that 25 a amp fuse for the a/f heater ?

[@CHINONSOSAMUEL73]

Good work Sir So is it only oxygen sensor that bring brine box light on dashboard Because I'm into mobile engineering

[@elberzatarain4746]

Hi what would that be the resistance of the A/F ratio sensor on a 1999 Toyota Camry?

[@edwarddillion8048]

Yeah I replaced the bank 1 Sensor 1 for a p1130 code on my 2000 lexus es300 . Didn’t change the error at all . I replaced the maf sensor. Installed new intake hoses and it’s not misfiring anymore but that damn code is still there and I’m at a loss and I have no idea we’re to go from here.

[@vwwrenchie314]

That van qualifies as a "creampuff"...mint😎

[@samaelmartinus3273]

I have p1135 bank 1s1 , and p1155 bank2 s1. Will fixing p1135 bank 1s1, fix p1155?

[@prtbone78]

Does erasing the code with scanner leave a code when rescan ? Like I'm internal permanent code? P100 something like that. I had scanned my old Ford escape it had that code.eant someone erased any code

[@billsimpson604]

Platinum, palladium, or rhodium heater wire inside it? Not cheap metals.

[@horsesilike5806]

You said you were looking for 11-16 ohms for the heater element and the new one had 1.9 ohms which would be out of spec. The new one worked so did you have the wrong specs?

[@kingsora5377]

He might of mis spoke. Mines was 1.9 as well.

[@danf8721]

What sensor and bank did you replace?

[@donnierobertson3088]

Nice job and video

[@mobilecommunicationsnetwor5268]

Could you have sourced from RockAuto or online Amazon for a lower price? Just had the customer wait for the lower price.

[@LAactor]

They can, but you save maybe $60 or so. And in process you could lose the customer. Depends on the shop, but many will say okay but pay more. Pay for diagnostic fee and maybe come back. No guarantee if money for the diag will be applied to repair.

[@patrickthomas6170]

278 at dealer : 138 at Rock Auto ,genuine Denso part #234-909

[@landrover4444]

I just bought a Denso OEM O2 sensor, Bank 2 Sensor 1 (Upstream) on Amazon for $42 for my 100 series Land Cruiser. $200 seems way off.

[@kingsora5377]

Just bought the part. It was 188 at autozone. 135 at Amazon and 400 at dealer. You sure you didn't get a narrow band denso cuz those are cheap. Wideband the one required for that engine is price as mentioned

[@rock_0075]

Hi, Thanks for the video, I have toyota corolla petrol 2002, one day the engine light came on and start loosing power (i had to high rev to drive the car), took to mechanic but the his computer cant read any code , not sure what else i can do. on low speed the engine light stays on but when i go high speed the engine light start fleshing. any guess please?

[@LAactor]

Clean the throttle body and MAF sensor first. Easy and then try again. If not, clean EGR and/or seafoam in the intake. Go to another mechanic, if light flashes is a catastrophic warning, but if not illuminated, not stored, need computer to check code history, not just active codes.

[@timchen7424]

[@karkule5919]

$300 for that..?? I bet it costs Denson $5 to manufacture.

[@SeanPopify]

That Sienna has had problems with the electrical system at 26k miles... Maybe that damaged the sensors... Or, more likely, the fact that it suddenly is being driven is loosening up a bunch of contaminants and it caused an overheat or some other damage to the sensor. They changed the timing belt and water pump at 30k... Gotta say this, the previous owners did the right thing basing service not only on mileage, but age as well. I wish I were so lucky. Every used Toyota I've seen in SoCal has been overpriced and in need of repair. The low mileage ones, especially! An elderly woman's son, selling her car said "perfect" and "excellent..." All four struts were leaking. Blown by her driving over curbs, no doubt. Electrical problems too. What does he do after I tell him about the problems after my test drive? He takes it into the dealer and pays for a $100 oil change, conventional oil no less, spent a bunch of money on fuel treatment and other useless stuff, yet didn't fix the struts, replace the tires or deal with the alternator/battery. Then he comes back and says he's raising the price. Basically, he said "I don't want to sell the car." It is at the highest range bluebook for an "excellent" condition car. I have a million of these stories. If they haven't tinkered with the odometer (I have seen a lot of that, completely documentable), actually maintaining it, they're asking as much in a private party sale as a dealer would for the same mileage and same model. They are drunk with the thought of becoming rich off of selling a 10+ -year-old Toyota.

[@cuongandmari]

Peter, you did not measure resistance on same pins on the old one with the new. On the old sensor you measured one top and one bottom pins but on the new sensor you measured both top pins. I am curios if the old one was bad?

[@nickv4073]

Well, the code went away with the new one which confirms the old one was bad. I dont think you have to be a detective to figure out the answer to your question.

[@patrickthomas6170]

Measure between the silver tabs (black wires) not the copper ones
