... First, I have had a mechanic look to see why, the light would come on. He could not tell me.
So, when the light would come on, (often). I would disconnect the negative side of the battery. That would reset the computer.
It would come on, in about a weeks time, After reset.
I am tired of disconnecting the battery!
There's something wrong, disconnecting the battery just resets the code until the computer runs through the cycle and sets it again. Go to another mechanic!
.... With all that said, I have been dealing with this, for over five years now.
I posted a thread (here) back in 1-9-2016, asking about this...... I did have Auto zone check it out, back then. And they did find, banks 1 and 2 was running lean.
And when I did take it to a mechanic, he could not find any leaks or anything wrong. He said, it could just be in the computer, like many other vehicles
I do not remember, if he change the fuel filter or cleaned the sensor from the MAF housing, deleted the EGR or check the PVC lines. I will check those items again.
My 02 runs good, I am just tired of looking at the...check engine... light.
.....stoffr, How old are you?.. 12.. You're a DUMB ***,
Just to let you know, That nut, holding the steering wheel, has nothing to do with the check-engine light.

You two must be related.......
Note, I have not disconnected the battery, for about a month now. and no.
