I had the same thing happen to me once before, it was cool night out and i was running the car hard, EML light came on aswell as the Traction Control light when i downshifted to get off the highway. The car ran like crap while trying to accelerate. It did not accelerate very well at all. Parked the car, read the code, same as yours, turned the car back on and it was gone. Weird tho. Never had this happen before and it has not came back on since then, 2 months ago.
