My daughter's service engine light came on and the code reads PO441. The local service center that I take the car to could not identify what needed to be redone. They reset the computer but the code came back at the next start. They suggested that I take it to the local dealer, but taking it to that shark is a last resort. Any suggestions? Haven't found much on the net. Thx
