Hi - The Check Engine Soon light is on on my 1997 Grand Caravan (3.3l engine). I checked the codes and got 12 - 31 - 55. According to AllPar.com, that means the battery has been disconnected recently (it hasn't) and it has a Bad Evaporator Purge Solenoid Circuit or Driver. The battery could be because of some corrosion on the terminals? I have no idea what to do to repair the other code. Any tips on how to check this out? Thanks - Brian
