Listings of the trouble codes for the various engine control systems covered in this manual are located in this section. Remember that a code only points to the faulty circuit NOT necessarily to a faulty component. Loose, damaged or corroded connections may contribute to a fault code on a circuit when the sensor or component is operating properly. Be sure that the components are faulty before replacing them, especially the expensive ones. The Assembly Line Diagnostic Link (ALDL) connector or Data Link Connector (DLC) may be located under the dash and sometimes covered with a plastic cover labeled DIAGNOSTIC CONNECTOR.

  1. On all 1990–95 models the diagnostic trouble codes can be read by grounding test terminal B. The terminal is most easily grounded by connecting it to terminal A (internal ECM ground). This is the terminal to the right of terminal B on the top row of the ALDL connector.
  2. Once the terminals have been connected, the ignition switch must be moved to the ON position with the engine not running.
  3. The Service Engine Soon or Check Engine light should be flashing. If it isn't, turn the ignition OFF and remove the jumper wire. Turn the ignition ON and confirm that light is now on. If it is not, replace the bulb and try again. If the bulb still will not light, or if it does not flash with the test terminal grounded, the system should be diagnosed by an experienced driveability technician. If the light is OK, proceed as follows.
  4. The code(s) stored in memory may be read through counting the flashes of the dashboard warning lamp. The dash warning lamp should begin to flash Code 12. The code will display as one flash, a pause and two flashes. Code 12 is not a fault code. It is used as a system acknowledgment or handshake code; its presence indicates that the PCM can communicate as requested. Code 12 is used to begin every diagnostic sequence. Some vehicles also use Code 12 after all diagnostic codes have been sent.
  5. After Code 12 has been transmitted 3 times, the fault codes, if any, will each be transmitted 3 times. The codes are stored and transmitted in numeric order from lowest to highest. NOTE: The order of codes in the memory does not indicate the order of occurrence.
  6. If there are no codes stored, but a driveability or emissions problem is evident, the system should be diagnosed by an experienced driveability technician.
  7. If one or more codes are stored, record them. Refer to the applicable Diagnostic Code chart in this section.
  8. Switch the ignition OFF when finished with code retrieval or scan tool readings. NOTE: After making repairs, clear the trouble codes and operate the vehicle to see if it will reset, indicating further problems.

GM/Cadillac OBD1 Codes E91 & F47

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

Ik am getting when I do the code check on my 92 cadillac deville 888 then the E52, then F31 then a 7.0. What does all this mean?


Hello: Here is a breakdown of the codes you have: 888 is the segment check which tells you the system can display all codes, E-52 tells you the battery has been disconnected. It tells you that an idle learn should be performed. This idle learn is a very long procedure, you need a Service manual to perform it. The F-31 means there is a communication problem between the fuel data panel and the BCM (body control module). Most likely a Fuel Data Panel, but it could be wiring and/or a intermittent BCM. It would require intensive trouble shooting. 7.0 means the self diagnostic system is ready to go to the next step. If you go to Auto Zone or Advance Auto Parts you can buy a manual for your car (about 20.00 Dollars) I would like to be of more help but what you have requires hands on troubleshooting.

1992 cadillac Deville OBD code read out and what it means.


E13-Oxygen sensor voltage stays between 0.307 and 0.609 volts for 64 seconds. Engine was at normal operating temperature at a speed over 800 RPM.
E44-Right oxygen sensor was lean for more than 50 seconds when engine was warm and at 800 RPM or greater.
E52-PCM has lost primary battery power.
E58-Pass Key fuel enable was not correct.
F47-PCM has received bad data from IPC for 3 seconds while engine speed was 500 RPM or more for 3 seconds.
F48-EGR open command was given during off idle operation. EGR opening should cause the mixture to be slightly richer because of the low oxygen content of exhaust gas. Vehicle speed was over 35 MPH and engine was warm.
Good luck and hope this helps, keep me posted be glad to answer any questions you may have.
