bschelle Posted January 28, 2004 Report Share Posted January 28, 2004 My ses light came on. I have a 99' Deville with 102,000 on the odometer. I just had plugs, all filters and the trans serviced at 97,233. I get all of the following codes: P0122,P0404,P0741,P1122,P1527,P1599,U1255,B1327,B2471,B2477 and U1255. Can anybody tell me what they all mean or steer me to where I can look them up? Runs great otherwise! Thanks in advance, Bill. Link to comment Share on other sites More sharing options...
