RHUDGINS Posted December 18, 2006 Report Share Posted December 18, 2006 Hi I'm looking for some answers. I have a 02 Cadi Deville with 98,935 miles on it I recently took it in for a system analysis check because the Check Engine Light is on. This is what I was told: Code PO102 MAF Circuit Signal Low Problem no present at this time PO440 Evap, System Fault PO443 Evap Purge Solenoid Control Circuit Fault Pigtail for Purge Solenoid PO463 Fuel Level Sensor Circuit Signal High/Open Recommend Fuel Level Sending Unit PO741 TCC Performance Stuck Off P1862 Torque Converter Clutch Solenoid Circuit Problem What exactly does all of this mean and which should be address in order of importance. Lastly does anyone know the cost I'm lookin at? Any suggestion are highly appreciated.. Lastly if anyone knows a good shop in the St. Louis Metro Area.

Ranger Posted December 18, 2006 Report Share Posted December 18, 2006 Do a search for TCC or P0741. For the $2000+ cost of repair, you can live with that one. P1862 is what is causing P0741. P0463 is in the fuel tank. $400 -$500 is my guess, but the '02 Deville may have an access panel in the trunk so the tank may not have to be dropped. That would save labor and $$$$$$ P0440 & 443 are related. Probably need a new purge solenoid. Not a bank breaker. MAF code not present, I'd clear the code and not worry about it unless it returns.

WarrenJ Posted December 18, 2006 Report Share Posted December 18, 2006 P0741 is the one that would scare my pants off. Keep in mind however, this can often be a "nuisance" code. If it's a HISTORY code, I wouldn't worry about it. If it reappears consistently, well . . . . . I'll buy you a beer and you can cry in it. Best, Warren There is no means of avoiding the final collapse of a boom brought about by credit expansion. The alternative is only whether the crisis should come sooner as the result of a voluntary abandonment of further credit expansion, or later as a final and total catastrophe of the currency system involved. - Ludwig von Mises Link to comment Share on other sites More sharing options...
BodybyFisher Posted December 18, 2006 Report Share Posted December 18, 2006 I recently took it in for a system analysis check because the Check Engine Light is on. This is what I was told: Where did you take it for a system analysis check? Did they charge you? You car has an on board computer that you can do your own "system analysis check" on. See this link which will show you how to read the codes: http://www.caddyinfo.com/readingcodes.html Are you having any driveability problems? With the amount of codes you are having you might try disconnecting the battery and cleaning the battery connections really good, pay attention to the positive cable you have to take it apart to clean it, remove the red insulator watch how it comes apart so you can re-assemble it. One of our members Logan just had the P0741 problem related to the TCC solenoid: http://caddyinfo.ipbhost.com/index.php?sho...c=11896&hl= and here: http://caddyinfo.ipbhost.com/index.php?sho...c=12067&hl= 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...

I would want to have the codes set several times to be certain there is a consistent - fixable problem. The instructions for reading and clearing codes are here http://caddyinfo.com/readingcodes.html Sometimes evap. related codes can be tracked to a loose gas cap. Jim Drive your car.
