There is no ground, and I have noticed over the last 4 days or so, I did the 1200 trip and the hybrid did great, I avraged 33 MPG, the check engine light would only come on if I were to let the enging cool down. Like when I drove 9 hours stright the light never came on once. But when I pulled in to my friends dorm parking lot and let it sit over night, when I got back in the car the next morning, the light would come on for the valve. And then I would clear it and never see it till the next morning.
