I have a 04 Cadillac deville and the check engine light is on after servicing all the codes and even tried replacing censor. Why will it keep coming on even after resetting the system?

Have it scanned yet again, to see if something new has been detected or one of the 'fixes' didn't work. What codes did you get? If it's a long list, forget it, can't do through a dozen

Had it rescanned and same codes keep showing up. 2 emissions and 1 transmission
