Hey guys, 3 of our engine lights came on on our Outback Diesel so I hooked her up to the OBD2 reader. the following codes popped up P0409: exhaust gas recirculation position sensor performance P0403: exhaust gas recirculation circuit. I believe i need to replace my exhaust manifold/02 sensors. Anyone had this problem before? Any help or info would be a great help. Thanks a lot, JM
