(repost since first one misteriously disapeared...)
Today on my way to a party...
While I was waiting at a stop sign for traffic to past...
I notices something orange illuminate my steering wheel...
I was like, what the hell was that?
Looked down...
My Check Engine Light was on solid...

But The Runner is running fine...

No Smells...
No Sounds...
No Shakes...

It is a:
97' 4Runner SR5 3.4L V6 Auto 4WD
99+k
Oil change last done 2K ago
All fluids check out normal...
K&N air filter
Belt changed at 60k like recommended....
Not due for another 2k...

I have searched with no luck...
I am sorry for asking again...
But everyone has some sort of symptom associated with the light...
I do not...


What is a common problem for that light to come on for my make model and engine?

I see the MAF is one but it looks like there are symptoms involved with it...

I am going to auto-zone tomorrow to get the code(or codes) pulled to see whats up...
I just can't afford another repair...
This is a Toyota...
I never though I would have this problem...

But any ideas at all as what it could be?

Could be a lot of things - an 02 sensor, any number of things can kick that light. Most likely inexpensive to fix.. Could be expensive of course, pull the code and you'll get more help!

Elton

have the code pulled and tell us what it is

YotaFun

Will do tomorrow...

Just trying to see if there is anything that can go wrong without symptoms...
But I am starting to see as ai read more and more that I can be ANYTHING...

uh...

I just need to cool it...

lol

Usually when I am stressed out, I hit the trail...

But now I can't even do that...

you could have a dirty maf, you could have had a misfire happen, lots of things, your local discount or advance auto parts store will pull your codes for free, and after you fix them they can clear them for you

WATRD

There are literally hundreds of codes that can cause the MIL to come on. (http://www.wattora.com/mods/obdii) There's no point in guessing at it. Get it read, then ask about fixing the problem.

Toyota's are dependable, but if you expected it to never have any problems at all, parts never to wear out and for it to last forever, you didn't pay enough

Do yourself a favor, lose the K&N and run a stock filter, even if the code is for the MAF. That will eliminate one reason for the MIL to turn on.

MOM: Yotafun(cause i dont know your real name), Your going to have to sell the 4runner."

MOM: "your girl! oook son, give me a pros and cons list on why i should let you keep it"

YOTAFUN: "ok. FINE, I WILL!...(logs onto computer...opens yotatech....new thread...MOM IS GOING NUTS, WANTS 4RUNNER GONE ....hey guys, threw a code and mom spassed out....what to do now...."

i hope i aint the only one laughing at this

CJM

^ I laughed out loud about that one!

Elton

fireteacher

im still laughing! bwahahahaha

love ya yotafun!

Elton

:pat: clean the maf and see if that helps

fireteacher

Elton

Actually I get something sort of similar. No symptoms or anything, except that the check engine light only comes on a couple miles into the first drive after I unplug the battery and then switches itself off 1 or 2 days later. It's really weird but since there aren't any symptoms, I haven't really done anything about it.

Anyone know what that could be about?

Only mod I've done that could have had any impact is a K&N FIPK.

progress4m

Of course it is just a guess with out a code but I would say it is your MAF- since you have K&N.
Try to clen the MAF....

gpcollen1

You do not need an obvious sympton to rear it's ugly head prior to getting a CEL. Your sympton could be very subtle - like gas mileage...

Red Neck Bill

i am haveing the same problem but i know the codes (Multiple Cylnder Misfire) but i have replaced everything and i still cant figure it out. Hope you find out what is wrong with yours.

YotaFun

HAHAHAHAH!!!!!
The scary part about this post is that is exactly how it went down last night!!!!

SO anywho...

Got the code pulled about 15 min ago...
P0136 O2 Sensor Circuit Malfunction (Bank 1 Sensor 2)

So yeah thats my prob...
Now I must look into fixing it...

::Still laughing::

So any ideas...
I will do another search again since I did see that the O2 censor was another common Check Engine Light problem...

Is this something that can be pulled out cleaned put back in and will be fine?
Or am I looking into getting another sensor?

Also the guy at AutoZone told me that the light had come on twice
This confused me since I remember the light coming on once and staying solid...
Maybe if I actually looked down at the dash a little more while driving I might have notcied it come on once before...

::Still Laughing::

I have become way to predictable haven't I?

YotaFun

You know I have noticed a decrease in gas mileage latly...
But I thought that was just because I needed to clean the K&N
(which I did 2 nights ago)
But after cleaning the filter it was back up to par...

The last time I got a CEL light was on my olds...
Found out some fuel return valve wasn't wrorking...
Which explained why every time i took the car over 80mph that I litteraly watch the full gauge plumet....
I had to drive at 50mph for a week before we could get it in...

RunnerUp

if i remember correctly people have cleaned there o2 sensors before, im not sure how you would have to search, but lucky for you these things arent that expensive. depending on how many miles you have you might just want to replace it, i had to replace mine around 85k and it wasnt that bad... good luck
