Hello all. Ive just started driving my Deville again for the first time in about 1 1/2 years. It runs like new but Ive come across service engine soon light. pops on every day after driving about 10 minutes. usually after reaching about 45mph. I checked the codes and got E39 and E52. I just got the emissions done August 24th Passed (light wasnt on then) Just started about a week ago. can someone tell me these codes and what to do about them??? Also I forgot how to reset the codes. Ive heard that the E39 is " TORQUE CONVERTER SOLENOID " If so, how to I get this taken care of? Is it in the transmission? Im usually a do it my self er, but Im not sure what a Torque Converter is .

Its a 1991 Sedan deville, FWD, 4.9 liter

There is a sticky at the top of this forum for codes. You are in the wrong spot, however: this section is for RWD Cadillacs.
