Bought this car about 9 months ago, and just now I'm getting a p0715 code with the engine light. The previous owner kept meticulous records on this car, and I can see she had the code 3 times before over the life of the car. The dealer flushed the transmission at one point, cleared the code, and told her if it came back there was a "transmission problem." It did come back, months later, but she took it to a different mechanic, who cleared the code again. So it looks like this code comes around every couple of years. The car drives fine. Any ideas? thanks.
