Question about 1991 Cadillac DeVille
Posted by Anonymous on
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
