Hi .......

Does the CEL have to be reseted manually or it can turn off by its own ?

I have now a CEL giving oxygen and KS codes.........

 

Not unless it burns out. That's the only way I see it.

 

First of all, holy hell your post was hard to read.

Second, yes, if the problem triggering the code is fixed/stops happening, after a while it will clear the code(s) by itself.

 

Thanks man

 

i had an o2 and knock sensor code. lasted for about 2-3 weeks then went away.

 

lol..... he edited it and i still cant understand what he wants...

 

holy crap...agreed with pmohr....your post is ridiculous hard to read..and you even edited your post, i wonder what the hell it was before.

Anyways, the only time i know that the cel will come on and off by itself has to do with the o2 sensor. The o2 sensor is intermittently failing. It still works, but not properly. Mine has been doing that and my mileage hasn't really been hurting. I usually don't like to fix things until i absolutely have to. But that's just me...

 

I will translate:

 

My CEL turns on and off by itself, every few times. i know it's the O2 sensor on the intake i just jiggle it alittle and it goes off.

 

Err...there is no O2 sensor on the intake

 

i got an emissions code on my max last week. im pretty sure its the gas cap because i got gas 2 days before the code came on . Is that going to eventually go off on its own?

 

I guess its your gas cap

 

Maybe he was talking about the IAT?

 

 

If the issue is intermittent, and the issue is temporarily (or permanently) alleviated for a predefined number of system cycles, the light can go off. I take it yours turned off spontaneously?

 

No...but I hope it will

 

Yeah, that's what i meant. Brainfart...

 

I just had my CEL come on about 2 days ago and shut off after driving about 50 miles....?????

I had this happen to me earlier on in the year too...

Not sure what is going on, but car is running just fine.

Got 177,000 on her and it seems everything is working.


Wondering if the extreme temps here in WI has something to do with it

I don't have a code reader or I would have figured out more about what is going on.

 

I have seen it happen in cases where it was not a "hard" code

 

well isnt it if u drive for like 50 miles or something ur car will reset it self. or vica versa

 

Yeah, I've had O2 sensors throw the CEL on and off before. Doesn't mean the problem is fixed however…
