2004 s60 2.5t awd code p2477
 

check engine light came on today; autozone said it came up trouble code p2477; but they didnt know what that code meant nor could i find it on list of codes on volvo sites; does anyone know what this code means? my regular service message came on yesterday, the car seems to run fine except there is a slight hesitation sometimes when i step on the gas; any help would be appreciated; thanks
