SOURCE: my remote will not work on my 1993 cad sedan

sometimes the remote will not transmit for whatever reason, i found when changing the battery in the remote or not using it for a while it may dissconnect itself, so next time it doesnt work press all the buttons at once for about 10- 15 seconds or until the car makes a noise or lights up and it should reset the remote and car

SOURCE: Cadillac Deville 2000- Engine check light code P0741

If you like go ahead and let someone sell and replace your transmission but here is my suggestion! Check around and see if you can find a minor vacuum leak! This can simply be the big round hose that goes from the fuel injection to the power brake hub! This is normally a push in connector which has about a 1/2 inch hose clamped on it! If there is any kink or the connector is not in correctly a leak will occur and the transmission will shift rough as though you will be thrown out of the vehicle! Try unplugging this connector and plug it back in hard and straight and maybe you will be lucky and fix your problem. If the vacuum is correct your transmission will shift better than you have ever experienced!

SOURCE: my 2001 cadillac deville keeps giving me dtc code system to lean

Anytime I get a too lean DTC I first change the fuel filter if it hasn't been changed in awhile. You'd be surprised how many times this has helped.

Good Luck with it.

Where is location of idler sensor on 92 sedan deville

When the service engine soon light (Also called the check engine light or engine management light) is turned on this is to alert you to the fact that Powertrain Control Module (computer) has detected a failure somewhere in the systems it controls you may not feel any difference in the way the engine runs, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

1988 cadillac deville sedan headlights stay on when engine is turned off. fuse or sensor or should it be hooked to a diagonotic testing machine

If the lights stay on for more than 30 seconds after the engine and switch are turned off then it may be time to have the diagnostic check. Many auto parts chain stores will do this for free and tell you what needs replaced as they want to sell you the parts required.

I've had transmission overhaul kit performed Oct 2007 on 2001 Cad Deville: incl upper/lower valve body w/solenoids,imput carrier, converter @ 77K miles. My check engine light came on a wk ago at 91K...

yes they are all right, i suspect that this vehicle uses encrypted software for the gearbox computer and this is the reason for the different codes ,i never use a code reader as on europeon cars they just show cannot connect to vehicle ,i use a voltmeter and a dwell meter plus a frequency meter and a scope to diagnose problems .So i suspect

P0741....Torque Converter Clutch Circuit Performance or Stuck Off

P0507....Idle Control System RPM Higher Than Expected

that this dealer doesnt have the correct diagnostic software because their code is a generic code as well as the first one ,A GM dealer code would have been P1507 and this code doesnt exist in the GM list of codes ,i think they are both right and need attention but the gearbox code is a fault with the front clutch operating mechanism ,i would advise ripping teh autobox out and fitting a manual gearbox ,lot less hassle
