AnswerE52 mean that battery voltage was removed from the computer sometime in the past, Such as someone removed a battery cable from the battery.
E75 meand a fault in the VEHICLE SPEED SENSOR.
E91 means that the PRNDL (neutral starter safety switch) is faulty.
EE91 means that the PRNDL (neutral starter safety switch) is faulty.
.7.0 is just telling you that you are at the end of the codes sequences.
The E codes are HISTORY codes and are of no concern.
The EE codes need to be fixed NOW.
You will need simple Electrical schematics, Test procedures and picture locations of the components within the system that is causing you problems of which can't be done on this website which only allows one picture. I do not have a website so you will have to e-mail:
