97 E300D engine codes
 

Hello, Im new to this group. We have a 1997 E300 Diesel with the "check engine" light on indicating engine electronic problem. After having a friend scan the codes we have 2 codes "1365" and "1367" my friend said he can only tell me it seems to be emission codes. The car runs fine and gets great fuel mileage, can someone tell me specifically what these codes mean so I can try and correct the problem and get the engine light to stay off?
Many thanks, Curtis
