Hi i just bought a 2000 volvo s80 t6 se last week and loving it. The car drives so quite and so smooth driving it for a week. But today suddenly a check engine light come on and stays on but it drives the same, still so smooth and quite. Could it be possible hat this,is just some faulty warning?

 

well what are you waiting for go to a auto shop and get it scanned for a code for free..just as simple.
You dont want to wait or ignore

 

sometimes these cars dealerships clear the codes without fixing problems, and they reappear after a hundred miles...

 

Thanks guys

 

Went to a volvo mechanic, they said its just a sensor in the exhaust pipe- to fix $1000!!!!!! There are 4 sensors in exhaust and only one is not working. I bought my own obdII tool now.

 

WOW that is $$$$. what was the code number that was pull up

 

The mechanic didnt give me the code. I havent use my obd2 yet. The mechanic may have deleted the code.

 

I will check later akabond if some code will come up from my obd2

 

More than likely it's a bad o2 sensor. Depending on the fault, it could take several hundred miles to reappear. You can scan the system and see if the code is in there.

 

like this?

 

I was referring to using an OBD-II code reading scanner.

 

Akabond, how did you get these messages on the panel?

 

if you read the footnotes that should show how to do it.

 

The mchanic has deleted the code, it doesnt show in my obdii anymore, but i still have an x on CAT and O2S when i do a ready test. The mechanic theres no urgent things i need to fix in my car as it is driving great.

 

Check engine light has come back on again. Used my obd2 scanner tool and it gave me P1132 o2 sensor heating circ.. Bank 1+2-sensor1short to B+. ... I have no idea what this means. Can someone help me, is this a minor thing or i must get this fixed?..... For now, i just erase the code so my check engine light will go.
