Car goes into limp mode when it reaches temp

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. You did not mention which engine your G6 is equipped with. I'll have to guess a little as a result. P0452 is evaporative emissions system related and will not cause "limp mode". P0522 is the oil pressure sensor circuit concern you've spoken about. P0106 and P0107 deal with the MAP sensor. I am not seeing a cause for entering "limp mode", but something else may be occurring to result in that.
