Question about 1993 Cadillac DeVille
I found error codes E40 and E52. What are they?
E40 is a problem with the Power Steering Pressure switch. Most probable cause is that if work was recently done, someone forgot to put the wiring harness back on the pressure switch. The pressure switch is usually mounted on the high pressure line. It looks similar to an oil pressure switch. If the wiring is correctly installed, the switch is probably bad (assuming that your power steering works).
E52 is a PCM (engine computer) memory reset code. Have you disconnected the battery of late? If not, check all your fuses. One of the fuses for the PCM may have blown.
