Ok so I had a u1510 code. Refused to pay 250 to 300 for a whole assembly. I eventually found an actuator for sale new on eBay. I did check what wiring I could without an oscilloscope. Anyway I replaced the actuator and fixed the U1510 code. I took out all the shutters except for the 2 the actuator is connected to. So now my problem is I have a p059f code. With a bidirectional scan tool I can open and close the shutters. My guess is that the ecm isn't seeing the coolant temperature rise enough and it knows that the shutters aren't closed. Specifically I would like to know what parameters there are for the shutters to open/close. What are the conditions of the p059f code. A schematic would be helpful if someone would be able to shre with ground locations. Thanks
