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.
So just for clarification, the code is being thrown because cause the main feed valve, in this case thermostat, is failing? Because it sounds likke the dude in the vid misdiagnosed the problem. If the bypass is activated, that means the main has failed.
it's almost like the oil coolers on the 3.6 Pentastar from Chrysler always leaking. No TSB's or recalls for it, but it's a known issue across any shop at this point.
Older Nissan VQ-35DE ENGINES have those too but they are in the form of a thermostat and located in the rear top of the engine and are called "water valves." I learned this from a repair video on my 2001 Nissan Pathfinder, very hard to get too have to take the whole top intake apart to get to it. Yeah, shitty vehicle designs
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.
Haha like the old VW rabbits with the odometer counter to trip the egr or cat light ,early ones had a box on the speedo cable and later ones had a switch on the back of the cluster 😂

I own a 2012 Tacoma 2.7 and had my engine blow due to a head gasket leak.

That's actually a parts failure in their models from 2019 to 2022...many other owners have been posting about the same issue..some only having 10k miles on the vehicle and others having the issue after 55k...it's a part defect and toyota needs to issue a recall.
Ok? The tech here is well spoken, clean, and intelligent. And they diagnosed the problem honestly and double checked with a meter. The customer was unable or unwilling to do this skilled labor. What are they supposed to do? Ask for a $20, a pack of cigarettes, and a handjob?
@@CCANGEL333 2019 Toyota RAV4 LE when I purchased it it had 24,000 and I drove it hard because I had a warranty to make sure if anything was going to break it was going to break while it was under warranty
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.
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.
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.
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.
Replace those things daily, it’s a bypass to raise coolant temperature for cabin heating. Warning to DIY guys there are a couple different variations on newer Toyota’s so be sure to replace the correct one and don’t crush the aluminum coolant pipes while trying to remove them. They will be stuck so be patient.
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.
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..
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.....
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
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)
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.
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.

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.
Why would you remove the plug on the coolant sensor to change the oil? Doesn't make sense.
Is it dangerous to drive with this issue or is it just a fact of losing the ability to have cabin heat or something like that for instance?
What's gun is when it wicks all the way up through wire and possibly makes it to the ecu
