Hello! Long time reader first time poster. I have a 2005 hybrid, and we have the dreaded p3125 code. I suspect a cooler pump, and have managed to get techstream going. I am hoping to get some second opinions of the output, or where I should be looking to confirm this. Is the MG1 temp a red herring? How about the high water temp? Also, if anyone else looking for help getting techstream going, there's a great article just search "techstream in 5 minutes. I also watched a video on YouTube by "jafffa adventures". Hint, if you have issues with it, change your PC's clock!
