Hello williamcole7: My name is Roger and I will help you. The code 888 is a test code. This tests the L e d's of the dash cluster. All segments must light so you can read all numbers. The 70 code means the system is ready and able to function. The ff code is a current BCM code and is happening at the moment. The f 40 code is a BCM history code and means it was a stored problem or something that has happened. The f 40 code is for a air mix door problem. THe BCM would set this if you had an A/C problem. The E 48 code deals with the EGR system fault. I would check for a vacuum leak at the EGR solenoid. The hose is prone to deterioration do to heat from the engine. Code E52 deal with loss of voltage. A dead battery or a disconnected battery cable will always set this code. None of these codes will keep the car from running.The repair schematics are to extensive to send in a reply. Should you need further help ao assistance I will be glad to help. Please rate the answer. Thank You for using Fix Ya. Roger

1992 Cadillac deville fuel dash readings are not right, reads wrong and states wrong gas amount, used etc. amounts. Can't tell how much gas in tank. So is this in the cluster under the dash or sensor in gas tank. It is a guessing game as to where have gas in car.

How do I check vacuum system for 92 Cadillac devill climate control system?


This problem is most often caused by the air mixing valve (usually its actuator has stopped working - fails in the cold position) so I would start there. Not sure about a 92 - could either be an electrically or vacuum controlled actuator. You can check vacuum at the HVAC control unit with a vacuum tester.

How do you find fault codes on a 91 cadillac deville


Turn your key to run (engine not running).
Press and hold the OFF and Warmer buttons on your A/C Heater Control Head.
All the segments will light up.
Look over at your FDC (Fuel Data Center).
Codes will be ran starting with E, then EE, then F, then FF and ending with .7.0.
The E codes are engine codes (current and history) and the F codes are body.

What do these codes mean E31-E41-E74-F31? can you help?


E31 = Shorted MAP cicuit sensor
E41 = Cam sensor circuit problem
E74 = Intermittent MAT

F31 = Display panels to BCM problem

This is to say if the vehicle is a 1991 Cadillac Deville
Then the Trouble Codes are as I listed above.
For future reference, the F is for BCM codes.

When entering the on screen diagnostics the display starts with one E for the PCM history, then E.E. for current. Same sequence follows for BCM codes starting with one F for history and F.F. for current ones

My code is e52 and f11 what is the problem


E52=memory(history)has been resetmeaning the power to the computer
was disconnected and the driving/engine systems performance history has
been lost.

If they are ONLY displaying as F codes this means that they are HISTORY codes and if they display as FF codes then they are CURRENT codes and what we need to diagnose is ONLY the CURRENT codes.

F11 = AC high side temp circuit problem.

hope this helps good luck
