Patience and attention to detail are the difference between average shops and great shops.

That pesky water bypass valve lol

2019 and newer Rav4’s have this problem. Not sure why it’s not a TSB yet since it happens on most of them. Everytime you see that message, it’s typically the coolant bypass valve. On some occasions it’s the electric thermostat.

That’s why it’s also called the money light!

Straightforward and clear. Good video

My dad had a 72 Mercedes that an idiot engine service light cube that had been added to the lower dash edge by the dealer. He had his old mechanic take a look to see where it was connected and pull it out. It only triggered the light after having the key on for so many hours that might have matched the usual 3000 mile oil change. It was truly a prehistoric money light.

The more sensors we get the more problems we get

That falls under the " You touched it last" clause. My Dad used that on me whenever something broke on our construction equipment. 😂

We need more mechanics like you ❤

Great diagnosis! Wish others were that committed to finding the correct solution.

They caught the problem and they fixed it instead of playing dumb! Everyone go here

Nice to have someone, who knows what they're doing, and that you can depend on!! Kudos to you!!

You changed my oil and now my taillight is out, it’s your fault

“That’ll be $500”

Their are 2 resets in the screen, scheduled maint and oil maintenance, I reset both every service

Quick tip when looking at manuals. Select F3 on your keyboard to bring up the quick find filter. Search for things in the documents through key words you’re looking for. It’ll instantly give you a amount result with automatically “teleporting” you to each matching word via up/down arrow

Finally another mechanic that knows what he's doin an can explain the problem luv guys like this honest

That is the exact same thing that happened to my RAV4 at 50,000 miles right after the oil change

My 1979 Ford f100 never had that issue. Still going strong.

Good catch. Thats a minor problem. Keep regular maintenance and drive on. 👍👍👍

Toyota in every way designs their shit to last like even the voltage tolerances are as perfect as possible

Part of the ever since club. And they don’t want to pay for it

I have that same snap on scanner. It is the worst Piece of crap I've ever bought, and over the years I bought a bunch of them. I sent it back to Snap on and they said they replaced all the hardware on the inside of it and that's all they can do. it's still doing exactly the same thing. It's very slow and glitches all the time. So if there's any future techs thinking about buying Snap on scanners don't waste your time or your money.

My GM car from the early 2000s will throw up a check engine light for anything that has to do with the engine or the powertrain of the vehicle. There also a vehicle maintenance light and a change oil light. The vehicle maintenance light I learned is when there’s something wrong with the vehicle that has nothing to do with the powertrain so this could be a burnt out light bulb or bad relays that are not working or a bad ground bad body control computer or blown fuses will all set that light. And change oil is just change oil.

Nice, informative, professional, to the point video. Thank you!

Great catch

Toyota is so Awesome. They told u exactly where to look 😊 Happy u had your ears open to listen and u knew what I were doing.

Good ole coolant migration! Love it. 😂

In other words. Customer got the vehicle back with problems it didn't have before. 😅

Thanks Henk!

This dude needs a serious raise!!

That's why I love the old school cars

I wonder why no one ever reads the owners manual for the car they drive?

The police sergeant in ,Stranger Things, has got side hustle wrenching.

Great tip.

Rubbed your meter across it

Used to write owners manuals for specialty vehicles. Dash icons were always tricky and took some digging. As time went on SAE J1939 kept adding and adding until every about icon known was on the dash. Wrenches, gears, wrenches inside a gear. Diesel particulate filter had 4 icons. Made a DPF quick reference foldout just to explain the system and what the icons mean when lit or flashing and what the operator is to do. There is a SAE schedule for icons but also depends what the black box engineers decide.

Learn something new every day ,nice catch.

nice work man!

My 2019 too. Accept i already had an oil change done and the maintenance message reset. The dealer changed the oil again. Even some dealers do not pay attention to the customers.

Glad you folks have the know how deal with newer vehicles. That's why I'd let y'all do my vehicle work.👍

Such a cute Bear, would love to see your fur!

I wish I had a shop like this to take my cars to

As you where so nicely rambling I did not catch what you were replacing! Please repeat it clearly. Thanks!😊

subarus with the new thermal control valve or thermal bypass valve also have a common issue involving no heat and coolant leakage

I own a 2012 Tacoma 2.7 and had my engine blow due to a head gasket leak. I couldn't afford to fix it so I learned to rebuild it myself and during that process I found my coolant bypass tube was completely shot as well as my temperature sensor and thermostat which I believe happened before the engine blowing and may have prevented it had I caught it. Good catch!

Thanks, good information

Hello What's the best used Corolla year? Thank you

Job security at its finest ❤. Fellow shade tree mechanic 😊

That bypass went bad on my 2019 rav4 also

What a life having to hunt these codes down. Nice find tho.

An honest mechanic 😮😊

This is a good mechanic it seems

Bad on Toyota for blurring lines unnecessarily. A code for a sensor fault is NOT a "engine maintenance" item. That is a regular "check engine" item.

Looks like a great Place to Lean on when changing the oil !.

Spark plug interval i think the older rav 4 did this or something the amout. Of stuff ive seen at firestone. Had to leave the drivers door open for 15 mins w headlights on to reset oil light for a 2010 jaguar 2 door i forget what it was

Super helpful, Toyota.

Good find

Certain Genesis sedan have a very similar issue, coolant thermostat housing has to be replaced due to coolant leaking from the sensor

My engine maintenance alert just came on and when they checked it they said it was a coolant bypass valve so I guess most of the corollas are having that problem.

My 350,000 13 year old KIA Sportage has never screwed up. Having a great car is a true blessing.

Thanks for sharing👍

I can hear it now. Ever since your shop did my oil change...

This is WHY u never get angry @ technician. Coincidental things happen. Many times I've done work on my car, & something totally not related goes bad.👍

Good mechanic

Miss older vehicles, so easy to fix yourself if you know what you’re doing

Didn’t know officer Hop was a mechanic part time 🙃

Man Toyota is just amazing

You got to love the eversense. Ever since you changed the oil in my car... I will admit, it was fun making customers feel like idiots

And that's why I only work on pre 89 model vehicles. Worked for Chrysler and customer shot a 9mm through main harness. customer stated car just shut off while driving. 2021 300. 3 days of diag and complete removal of interior to find

where is this shop?

I replaced my 98 Toyota corolla thermostat, who ever did the job before me. Put the thermostat in the put the rubber O ring over the thermostat, when I saw this is was surprised that there was no leaks . The rubber O ring should be placed around the edge off the thermostat, the O ring has a groove for this.

So the question is how did you get coolant in the wire connection and why didn't you take the care to prevent that?

Great, Toyota is using time-bomb parts now for more maintenance $$

That could be what's causing all the fires in Rav 4s.

Same exact deal on 2020 Camry se

I probably built that rav if it's from kentucky

I wonder does my 2018 rav 4 have this valve? I got the pre facelift before this one. i Guess i will check some time but i dont got no messages on the dash but i only got 40k miles though..

"when I ran my meter across it". Lucky...I only got a few inches.

im an expert Toyota Tech, been a tech with Toyota for 3 years now, on newer year Corollas and RAV 4 whenever that engine maintenance light comes on, its always the coolant bypass valve, always make sure you check the electrical connectors, when i did one on a 2017 Corolla, the coolant actually melted the wiring and i had to replace the two wires and the connector that go into the new bypass valve.

Coolant in the connector, oh yea I remember that kind of thing happening on older cars all the time.....😅 Weird tho, twice I've seen this within a week, never seen it before tho not in 20+ years of experience.....

I swear that over the years I’ve known more mechanics called ANDY than any other name out there!

I just had the same issue, manager was on me for not resetting maintenance light even tho i did haha

Back in the day you didn't have to worry about wire shortages as much. Simplicity of old vehicles are treasured by many now a days for that very reason.

That's one is pretty common on the 18+ Camrys and 19+ ravs

ah yea that'll do it, my grandfathers 2020 corolla had this same issue where the bypass valve took a dump unexpectedly, we took it to the dealership (since at the time it had warranty) but was first told it wasn't covered and that it'd have to come out of pocket, so we said no thanks and i was gonna do it in my shop instead since the part is cheap, but lo and behold, toyota actually called back and offered to do the repair free of charge since it was becoming a common issue (it still is)

Its 2023 scanners need to be built into the car, even bidirectional.

You do look like sherrif hopps from stranger things

Key things about this mechanic. He consults the owners manual. He accidentally floods a connection with coolant creating a short. He changes the piece. I like to hear he didn’t charge the client.

The wording is ambiguous. I could be wrong, but to me, the word "maintenance" means work done to slow or eliminate deterioration. Unless the manufacturer recommends changing that valve at a regular interval, then that falls under the term "repair".

It great to see a Honest service mechanic wherever you're at keep up the good work you might give people hope for good service mechanics as well as imports and domestic vehicles bro keep it up a lot of shops are f****** up people's cars not trouble shooting the right way they should have when they got schooled and experienced.

EVs eliminate most of this

Me and my wife we’re going to buy a Toyota RAV4 do you think that’s going to be a good pick or a bad pick?

Getting so many of these at our dealer, ravs, Corolla hatches so far , the Corolla is way easier since the hoses don’t have to come off

What year?

Well that's not confusing for the average car owner at all...

I am seeing a lot of sensors have this problem on newer cars. As long as people keep buying them, I'll keep making money.

You can clean it with contact cleaner and let it dry and it should be good

Just in for the oil coming back $$$$$$

That Zeus scanner is nice, as long as you have the features unlocked. I looked at the receipt today and my boss got it for 6,100.
