99% of the time e52 is just telling you the battery was disconnected in the last X number of starts. It will probably go away after a day or two of ignition cycles. If the battery has been pulled then any other trouble codes would have been cleared and will not come back until they are re-detected, May have to drive it a bit to get any new codes to appear to help trace your problems.
Check to see if you r battery is too low. They have security systems that protect the battery from reaching levels that will damage it. This will be the problem if you also see the security light flash on the dash and know there has been nothing to trigger it the battery being low will cause this. WebRepcurrentVotenoRatingnoWeight
E52=memory (history) has been lost.try ERASE all your codes and see if any come back.1.turn Ignition ON, Engine OFF.2. Push and hold the OFF and WARMER buttons until all the segments on the display illuminate and as soon as the codes start to appear, Push the OFF and HI buttons and release them until you see .7.0. 3. Turn ignition OFF.
Changing the fuel filter isn't a bad idea prior to getting into the O2 sensor. You may want to consider replacing the TPS (throttle position sensor). Do an on board diagnostic test to identify the areas of concern. Most likely you'll get error codes for both the MAF sensor and the TPS.
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 EGRsolenoid. 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
had the same problem on a 1993 sedan deville, replaced $700 in parts finally found engine was not grounded replaced negative battery cable, try jumper cable from negative side of battery to engine.
I fixed this problem by reading the computer troble codes, the code .E.E 12 indicated no distributor signal. I found the ignition module to be bad. All this with out the "experts" help.
i have two codes on my 92 cadillac sadan deville that read e 12 and e 96. i understand what they both mean. e12 is 'no distributor signal', and the other e 96 is 'torque convertor is overstrewsed'. i know that the toruque convertor is a big project itself, so im goin to send that into the professionals. but i might be able to fix the distributor, if it is the cap, or a false ground wire which hopefully it is. there is about 170,000 mi, and have gone threw alot of parts that i installed myself, but im not goin to let her go yet she still got alot of miles to go. i just need help on checking out the distributor cap for replacement.
