P0071, P0073 codes
Recently I broke and replaced my passenger side mirror. Since I replaced the mirror, I have CEL with codes P0071 and P0073. The EXT temp is stuck on 50. I swape out the ambient temp sensor with the old one because I believe it was still working untill I replace the mirror with an aftermarket mirror. Any help appreciated.

Just to update. After checking the sensor wiring and plugging everything back together. the ambient temp sensor started working and the CEL went away. So, I'm assuming that the plug for the mirror was not making proper contact. Thanks for the advice.
