So I put another engine into an 09 Outback and now am getting codes that never existed before. It runs and drives around town and through the neighborhood great but under load on the highway it shut down. The codes lead me to believe that there is a automatic transmission issue but that is a completely new situation for this car. Codes p1718, p0700, p0715, p0725 have all come up and it did so while accelerating hard on the interstate so as to merge and change lanes. There is no previous history of that happening in the car. The only thing I thought may have been an issue would have been the drivers side VVT solenoid since the donor engine had some battery acid spillage from the wreck on that side which may or may not have gotten into the electronics. Could this be due to oil temp sensors not operating or the VVT solenoid not performing?
