BajaRunner

OKay, Im confused.

I havent done anything to my 4runner for the past few weeks. Last thing I did was the Body lift, and that was like a month ago.


Now, all of a sudden, I turn my runner on, and my check engine light is on. I drove it around, no problems at all... Been like this all day.

I dont hear, see or feel anything wrong.

What do I do? How do you guys get allt hese diagnostic codes?

SC,

Did you check if it was the halogen fluid?!?!

You need a code reader to check the cause of the CEL. A few of us have the Auterra code reader. Search that term. Harbor Fright has a cheap code reader for under fiddy dollahs. Or your local auto parts store *might* plug their reader and let you know (free or at a price).

Autozone will read the code for free.

did you recently fill up on gas before this started happening? sometimes the gas cap causes the light to come on.

Did you check you'r horn oil? j/king , Autozone/ pepboys will plug in and read the code for free.

$10 on the MAF. Happens to me quite often.

That or the the TPS (throttle positioning sensor). Had my CEL on for that for close to a month until it finally started stalling on me :pat:
That's when I figured it was time to do something about it

yea ... free... the auto zone made me pay for the reader ($184.04 deposit) and 2 min later they gave me my money back? why couldnt they just have read it for me and save me and them time. i dont get it.

but yea ... take it to autozone

Had a 96 Taco that did the same thing (about 3-4 months ago) and it turned out to be the O2 sensor. It seemed to drive and act the same as if nothing was wrong.

Not in CA.

You're lucky! When I lived out there I had an O2 sensor go bad. Went to 3 different auto zones in the east bay trying to get them to do something similar for me. No one would budge, so I ended up just buying the darn thing. Some sort of regulation was passed that prohibits them from doing it.

If you're check engine light is on, the first thing I would do is hit you're truck with a little prop-wash.....sometimes it's hard to find, but if you swing by the local municipal airport you can find some pretty easy, just ask around.

Pretacopower

Yeah they do...I've had mine done twice.
edit: just read your following post That's weird that they wouldn't do it for you....maybe it's different from store to store

you just have to pay a deposit, and they give you the scanner
