i never see exhaust warning lights on before..

maybe u can check ur Oxygen sensor connector upstream and downstream 1st..

iszzit the o2 sensor faulty will make the fuel consumption high?

ECU use o2 sensor to regulate A/F ratio... faulty sensor leads to inaccurate reading thus A/F ratio can go wonky.....FC can increase!

correct me if i'm wrong....

yes...u r right...

that sensor quite important to the car..will determine ur car FC and also HP
