Hi! I own a 1990 sedan deville-real nice condition. I am having trouble with the service engine soon indicator. Ran the diagnostic routine and got codes E41, and E52. Where can I find out what these mean and how do I eliminate them. I'm sure it is the same question from most novices to this site. Help please
Check the electrical and technical forums. I believe there is a sticky at the top for all the codes and how to read/clear them, etc.
E41 is a cam sensor circuit problem
E52 is an ECM memory reset
