Unhappy New Check Engine Light Problem (CEL)

strange things happen to my car...*sigh*
here's the deal...my CEL(check engine light) comes on sometimes under hard driving.....actually...just during hard acceleration..and twice under hard cornering.....
has this happened to anybody else???!!!!
the CEL seems to reset itself after a few miles (50-100)
so far it has come on a total of 6 times..... the first time i brought it to dealer ASAP.....since then..the CEL turns off the light by itself.....(is my car scared of going to the "doctor"???? )
anyhow....i was wondering if anybody else has been experiencing this.....

What code did the dealer pull when you took it in the first time?

This is probably only "new" to you. What was the diagnostic trouble code? Please don't ask anyone to speculate about what might have caused a diagnostic trouble code to have been detected "just during hard acceleration..and twice under hard cornering..... " That's a bit too vague.

nope...the light never flashes...... it just seems to turn itself off after a little while..... i've checked all the main possibilities each time...(gas cap, fluid levels, etc...) =T
perplexing isn't it...
the strangest and thing i hate most is how it turns itself off... otherwise i could bring my car to the dealer a few times and maybe get me a new WRX

hehe...maybe i should read ALL the posts before replying...
anyhow, i have only brought my baby to the dealer once... the first time it happened... that is because it turns itself off after a few miles....
the dealer told me that they couldn't find any problems with my car and reseted the engine control unit.... the CODE was P1443
if any of you have a tech manual.... can u tell me what that means???
and what can i do about this...because it does turn itself off..
thanks guys

Well i don't know how much this helps.. but My car from when i first got it ... it was rather fast sometimes and slower others... until it totally kick the bucket on me... I started getting misfires all over the place and then my idle became screwed... so now my car is in the shop... sick as can be... on a holiday weekend and no clue wheni am going get it back...

I couldn't pull the codes until like a month ago.. and I guess that was a month too late..

let me preface this by saying "I'm not 100% certain", but I think that is the code for excessive emissions (uhhh...from the car).

Some of the WRX's (especially the early ones) have experienced CEL's as a result of a software error in the ECU. I took mine back to the dealership, they said it was a candidate for the ECU upgrade. They had it for a day and upgraded the software. I don't think the dealerships have the equipment to upgrade it - it had to be sent to the regional HQ.

I have not seen a problem since. Ask them about it. SOA also provided a rental car while it was being upgraded.

Good Luck.

P1443- Evap Emissions Control

Immediately after fault

Trouble Symptom- Improper Fuel Supply




IF that's the code you are getting. I would take it back to to dealer. Fuel Problems on turbo cars... NOT GOOD...

Default Do a search.

Do a search on 1443. There is a bug in the software, and most who have had this code have had their ECU sent back to SOA.

I had my first CEL yesterday
after having none for 15,000 miles.
With 1/4 tank of gas I did a sharp
90 degree left turn and cranked
it up to redline in first and second.
Then the non-blinking CEL appeared.
I just reset the ECU to clear it.
I usually don't let the gas get that
low and attribute the CEL to slosh in the tank
since there was nothing else unusual going on.
If it happens again with my usual fuel levels
then I'll take it to the dealer for diagnosis.

look for a blue T on the left, front side of the engine bay (kinda near the center of the engine, but left/front biased).....right under the alternator.....there are 3 hoses that get connected to the T, 2 of which run in-line with each other, but the third hose connects on the underside of the T......mine was not hooked up and since hooking it up, I have not had a single MIL (CEL) from the Evap System.......

A while back someone posted about this and I went out to my car and low and behold there was this blue 3 way T with only 2 vacuum lines connected....anyway, it worked for me.....and my car was one that was in the first shipment, I took delivery March 16.

The hose is hard to hook up....someone I believe actually pulled off the alternator....but if you work with it, using needle nose pliers and applying the right pressure in the right spot, it will go back on....it took me somewhere around 5 to 10 minutes......

the 2 times my cel light came on under hard cornering were about the same conditions.... cept i shift before redlining(bout 1000 before) I was thinking that it may have been just fuel slosh....but what about all these other people auto-xing in the WRX....how come they dun report these same problems......

I think i may have to call the dealer and just xpln the situation....
I'm gettin quite a few mods soon...(in the mail).....and i don't want to do ANYTHING before i'm sure my baby's alright.....

dug-e-fresh
Thnx for the tip....gonna go check to see if that's the case....
but.......doesn't anybody else think that it is kind of scary that SOA may of left a hose disconnected??!!!! I mean.... what kinda quality control is that?!!!!!

LttLDGN - p1443 is for moisture in the evap canister solenoid. The values/tolerances your ecu uses to determine this are too narrow (most likely). You should still visit the dealer, have them visually inspect and make sure there is no moisture. The fix is to swap/send back in to SOA your ecu and they'll reflash the unit. If you have a MIL, even if it goes out, the code is stored in the ecu. As long as you don't reset your ecu you can take it into the dealer any time and he can pull all the old codes (and they usually clear/erase them).

gee..i feel dumb.....

i shoulda known that the codes would be stored....hehe thanks....i'll check in with the dealer....probably is the ECU....and if i can get them to reflash it...(hopefully won't take TOO long).. then my baby will be ok

The dealer told me of another vacuum line that was off...but that was before the front T was connected so I still got the evap code....anyway, this hose is somewhere back near the gas cap. There is a black box looking thing under the car on the passenger side that I think has something to do with the emissions system, they told me somewhere back there a hose was off, thats all I know....take a look, you may find something....like I said, my T was unhooked so even if that had contributed to the problem, it was not the cure....for me.....maybe for you though...

Hope this helps.....

Same thing with me and the hose popping off the tee.

I just took zip ties and hooked em up... they just come off WAY too easy any other way...
