PAUL T Posted September 27, 2007 Report Share Posted September 27, 2007 On my Uncles 1999 Deville there was a code "P1483 - Engine Cooling System Performance". I do not have a 99 manual and I am not as up on these codes as I am with my 94 Concours, so what does this really mean? I have also been looking for a newer Caddy, 97-99 Deville, so I am trying to educate myself about their codes. He has had overheating problems and had the thermostat change and given a clean bill of health on the head gaskets, but he is still a little leary about any overheating codes. Also I did not know if it was a current or history code, my wife just called and had run the codes and just gave me the numbers. I will check into that.

BodybyFisher Posted September 27, 2007 Report Share Posted September 27, 2007 Did you check the bleed line? Air in the system would cause temp swings. Not near my manual either, this is just a guess Pre-1995 - DTC codes OBD1 >> 1996 and newer - DTC codes OBD2 >> https://www.obd-codes.com/trouble_codes/gm/obd_codes.htm How to check for codes Caddyinfo How To Technical Archive >> http://www.caddyinfo.com/wordpress/cadillac-how-to-faq/ Cadillac History & Specifications Year by Year http://www.motorera.com/cadillac/index.htm Link to comment Share on other sites More sharing options...
PAUL T Posted September 27, 2007 Author Report Share Posted September 27, 2007 Did you check the bleed line? Air in the system would cause temp swings. Not near my manual either, this is just a guess No, but the dealer was supposed to have checked it out for him. When my Aunt gets back home with it I am going to clear the codes and have her drive it a while and see what comes back. All indications were that the coolant was at the correct operating range. Anybody know what the code actually means? Link to comment Share on other sites More sharing options...
bowtie123 Posted September 27, 2007 Report Share Posted September 27, 2007 Hi, I have a 1999 Deville FSM and code P1483 calls for replacement of either the ECT sensor or the IAT sensor. Its a little difficult to get the manual into my scanner to scan the pages. Link to comment Share on other sites More sharing options...
