I just bought a 98 grand prix gtp last night and it is reading these 2 codes manufacturer control auxiliary emissions controls, evap emission control system pressure sensor low it also doesn't have any mufflers could that be why it's reading these codes I looked on here and Google and couldn't find anything myself
 


Ok, so now.... I'm going to and I suggest you also do. Google "GM DTC p0452" then substitute in teh 1404. That will give us the most info possible.
