check engine light
I have a 2001 volvo s80 t6 and the check engine light is on. i tried replacing spark plugs and resetting the light because it needed a tune up anyway and that didnt fix the problem. the light came back on so i had the codes read and they are P1174 and P1184 (these are the only 2 codes). I think the problem might be a mass air flow sensor but im not sure. has anyone ran into this problem and were successful in fixing the problem or does anyone have a clue what it could be. thanks a lot for any help.

RE: check engine light
Info from VADIS:
The codes are:
P1174 (ECM-260A): long-term fuel trim/ upper limit
P1184 (ECM-270A): long-term fuel trim/ upper limit (bank 2)
The causefor both:
Upper limit:
-intake air leakage
-exhaust system air leakage
-low fuel pressure
-defective heated oxygen sensor (HO2S)
Check forthe leaks and check the fuel pressure.
Could also be the MAF.
Wait and see whatTech says.
