Check engine light flashes during high reving - Toyota Yaris Forums

AlphaFox · 06-01-2007, 08:02 PM

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.

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

. 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.

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

besides that i say go crazy

barryware · 06-06-2007, 09:59 PM

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..

sounds about right

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....

no, it didn't and it won't happen to me-----the highest rpm i revved my yaris up to was 3200

and i'm not planning on going anywhere over that figure......if you need a performance car, why not get yourself A FERRARI...............

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

im actually curious to see what code comes up (if possible) next time it happens...

Straight up dude. 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.

AlphaFox · 06-01-2007, 09:51 PM

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

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

AlphaFox · 06-02-2007, 12:09 AM

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.
