So I have a 1997 Ford Expedition as well. My wife was recently in a little fender bender and now we are getting that 52 code. Does any one have any advice on if the low voltage problem is still the cause?

Any info would help because it seems to me that this code for most of the other people on this forum happened spontaneously.

Thanks

 

Observed a Bosch 1350 code reader used to work on this. Can't recommend what is needed for your car or what to do, just observed it at the shop.
