Check engine light flashes during high reving

[AlphaFox]

Has this happened to anyone else? when I stay near redline, over 6000 rpm, for more than a few seconds my check engine ligh starts to flash. today it started to flash and I didnt see it since someone was on my butt and I was trying to stay ahead, and then it just stayed on solid... I shut off the car and started it but it stayed on. its VERY weird too because I have a scanguage II and it logs codes, but it said there wasnt one... I kept trying to read a code but it said no codes found.. but the check engine light was on. HOW could the light be on but no code?? I ended up pulling the battery terminals off and waiting 10 minutes and then the light went off... very weird! if it had thrown a code I should have been able to read it. the light hasnt come back on.

anyone else see the flashing check engine light? it happened to me the first time when the car was bone stock, just flashed when I was racing my brother and stayed at 6k for 3 seconds. now I have 1/2 of my airbox removed, but I dont see how that would affect it since it did it even before I removed the box.

How and why were your rpms over 6,000? That's just asking for trouble. If someone's on your rear, let them pass, pull over, and just slow down. Just my opinion.

[drifto]

a flashing check engine light usually indicates a dangerous misfire is occuring. sometimes depends on how many cylinders are misfireing etc. if it stays on afterwards then there is definitly a problem. bring it to the dealership next time it comes on (dont delete it). just dont tell them you were reving the shit outta it:biggrin: . it also could be a cat restriction or a/f sensor reading incorrectly and putting too much air in the engine at high rpm. etc etc etc. just remember the ecu records rpm at the time the DTC is set. isnt there a TSB for our cats having an egg smell? if so maybe your cats defective, rsx's have the same TSB . if your cat is "too" hot it can cause problems at hi rpm esp.

no, it didn't and it won't happen to me-----the highest rpm i revved my yaris up to was 3200:smile: and i'm not planning on going anywhere over that figure......if you need a performance car, why not get yourself A FERRARI...............

[AlphaFox]

omg.. I gues I posted this in the wrong forum. I do occasionally playfully race people on the highway; nothing like drag racing or anything. jeez

lol you can rev it high, but you have to just be careful and understand the limits of the car. i say if you cant enjoy your car, then why have one? everyone has their own way of enjoying their car. some hook it up with a crazy system others for autocross, some just like to save gas and cruise in style. in the end its whatever floats your boat :thumbsup: im actually curious to see what code comes up (if possible) next time it happens...

[AlphaFox]

thats the thing, it didnt throw a code. unless I take it to toyota or something, im not sure what it means. probably just letting them know I beat on the car or something! I didnt have it up there that long.... I mean your supposed to keep the RPMs high when your racing, since over 3K is where all the power is. I take it to 6.6K and shift when im racing, that is the rev limiter, I mean if you shouldnt take it that high then why did they make the limiter 6.6K??

exactly, thats why ithink maybe the cat is prematurely worn or restricted. if possible try to duplicate the code again. :iono:

[AlphaFox]

If it does it again, I will have it checked.. hope it doesnt though.

A friend of mine has a Mustang. When he gets near the rev limiter, the engine light flashes. If you are too close for too long, at will stay on and if you hit the rev limiter, engine light stays on.

His Dad has got some type of diagnostic head made by snapon. It didn't show the code (rev limiter) even with the engine light still on. When he took it in, he was warned about abusing the engine and further abuse, may void the warranty. It seems that those type of codes that may report abuse are secret and you must have the right diagnostic head to read them.

I can not confirm or deny.. This is just what I was told.

[YarisPR]

You should chek that out cause I really rev mine hard everyday and no check engine light comes on.

yes it could store it as a temp code. where it wont sometimes read on a generic scan tool. but on a manufacturer specific scan tool the code will be listed in a seperate "history" or "temporary"section. and it may store the freeze frame data as well, which will inform the tech what the car was doing at the time... rpm, coolant temp, wheel speed, fuel trim, ect... for example, my mac tools generic scan tool doesnt always show me the same number of the codes that my honda scan tool will. esp codes saved in the temp folder. basically when the ecu decides that the car is back to normal conditions it can turn off the light after i believe 35 to 80 drive cycles depending if its a misfire code or not. however even though the light is off it may keep the code in the temp file for a longer time which can be accessed by the manuf. scan tool. hope this makes sense...

[mandriu]

I noticed in the owners manual that the car has an EDR system. That system would record information before an "event".

Patient: Doctor, it hurts when I do this...

you must be doing it on neutral and it makes it a different story :smile:
unless you ship your car somewhere outta Puerto Rico to race it on an open road.........

U sure haven't visit Puerto Rico jajaja you don't need an open road to rev hard. Here its all about small roads, curves and mountains and I asure you you can rev your car up to 6,500 on 1st 2nd and 3rd goin around places here :biggrin:

Not true....you can keep your Yaris at 6,000 RPGM all day long...the engine is nearly bullet proof, and it will take a beating plus more....that engine will not blow up at high RPM...it will last 300,000 miles of abusive use so long as it is maintained properly....no need to baby your Yaris...drive the hell out of it, if you must....it will not hurt it.

lol just dont panic shift while racing and downshift from 4th to 1st at 6k... ive seen it done many times :rolleyes: besides that i say go crazy:burnrubber:

[barryware]

Or.... Rev to 6K and then slide your foot counterclockwise off the clutch.

If you have an A/T like me.... 6K while in neutral, and when you think the traffic light will turn green, drop that bitch in drive and hold on.. :biggrin:

HA! Watch out! The Man's got his eye on you! :laugh:

That would make sense though. I can understand voiding the warranty from "abuse". Economy cars weren't designed for racing, thus treating it like a race car could naturally result in some problems that wouldn't have arisen if it was used under normal circumstances. Better slow down there, Speedy! :biggrin:

[gonzo452001]

that would kill me to do something like that to my car. my car will never see 6000rpm. I did have it 70mph in 3thd gear once didn't notice the rpm

[captainzerocool]

VW Jetta's have a safety feature (well for the manufacturer anyway) When the car hits its rev-limiter multiple times it would log a engine warranty void code within the computer. It would never show up as a check engine light. So be warned if anything happens it is all on you.

sounds about right :laugh:

[ddongbap]

Then whats the point of a rev-limiter? You might as well just let it run willy-nilly. Kind of lame.

BTW, does it say anywhere in the warrenty about a warrenty void, due to hitting the rev-limiter?

rev-limitier does what its name describes it limits rev during acceleration. however. if you dump the trans into 1st while driving at 4000 rpm in 4th theres not much that can stop that force from blowing up your motor. most people blow-up thier motor (non-turbo) when they misshift into a lower gear. not during regular up-shifting

Some of these post hurt my head. A rev-limiter limits revs, not stupidity... Do you run your car into walls because it has airbags? Do you risk sex with an infected person because you have condoms? It's a LIMITER, not a shift light...

I doubt you've seen it many times....who and why would anyone downshift from 4th to 1st gear? I doubt the manual tranny would let you do it even if you wanted to....

Way to go Corky...You're missing the point.

I'm saying, why have a rev limiter where its at, when running into it will void warrenty? Why dosen't Toyota just set the rev limit low, so when you hit it nothing will happen? Or why have it at all? If there is a recorder that'll void your warrenty, that'll have the same effect if your engine blows up. You'll be left shit out of luck.

The air bag anology isn't the same as the rev limiter. Hitting the rev limiter dosen't require a wall. Why the hell would an engine create all of its power so close to the rev-limiter? How would you gain all of the 8.whater (or whatever the 0-60 speed is) by not reving to where the power is? Everyone should create big bore, big stroke engines, so going near the rev-limiter would be worthless. Not to mention the non s models do not have a tach, so figureing out where you're at isn't easy for the new driver..

My X-Runner dosen't have much top end power. Well, it does, but I've got oodles of torque in the low end, so I wouldn't really have to rev so high. Wouldn't that be the solution to a rev-limit warrenty void?

If you think that hitting a simple rev limiter is SUCH a risk, to be compared to condoms, and air bags, then you really need to get some of your values straight.

... and that picture wasn't called for.

Don't worry dude. A few of the people here are worse than honda-tech.

Rest of you need to be a little bit more supportive to your Yaris breatherin. But then again, what do I know? I'm new here, and I don't even have a Yaris yet.

... and that picture wasn't called for.

I'm missing the point? My point is that there is NO reason to be that close to the rev limiter. Unless my Yaris is different than your Yaris, there is a definite
drop-off-point in power as the revs top out, so shift there. There is never a reason to be buzzing the rev-limiter for extended periods. Like I said, it's a rev-limiter, not a stupidity limiter...

The engine develops all of it's power at high revs because that is how it is designed. Again, when you feel the drop in power, shift. The max shift point does not change from day to day, try to remember about what it feels like, and SHIFT! If the Yaris made it's power low in the revs, it wouldn't get close to the same gas mileage, which is the basic point of the car.

What the hell is the "8.whater"?

If a manufacturer warranty's your product against defects, shouldn't they be able to monitor it for defects. That is what this "rev-limiter recorder" does, it monitors defects in the DRIVER. Why should the manufacturer be responsible for your abuse?

As for my values, I'm thinking mine sound pretty good. I don't do stupid stuff just because I have safety equipment...

...and the picture was funny :smile:

...and this will be locked soon, that's what happens when I get more than 1 post in a thread :iono:

[AlphaFox]

who said anything about driving at redline for days on end?
I was racing someone, and was at a point where if I shifted I would be making less power than if I kept it at 6K, so I did that. then the light blinked.

since I have installed a weapon R intake I have not seen the light return.

I think the power band maximizes WAY before 6,000 RPM....it is stupid to shift at start of red line...better to determine where the power is maximum, then shift just after that point.

And dudes, don't feel scared of near redline RPM's....at that point the engine does not wear out any faster then at mid level RPM's....as to engine wear, 90% of that happens during morning starts, and up to 10 minutes after the engine is running....oil needs time to get to operational temperature...too thick, it does not flow as well...and it is engine flow (more then oil pressure) that protects the engine the most.
