I constantly through a PO452/ PO454 code whenever I play my music too loud. I've had the sensor replaced twice thinking that was the issue. I try opening my windows up fully to allow the pressure to escape. Anyone one else with this issue? I can get it cleared, but am tired of constantly having to do so, just looking for a more simple method, preferably avoidance will maintaining my sounds.

Psycho EVAP?

Ooooh kay, even though I only play my music "obnoxiously" loud when I'm out of populated areas. It is up to me how loud and where I play my music. I would appreciate all comments that aren't geared towards a solution to be kept in the minds of those who have nothing else better to do.

Also, the light comes on WITHOUT the music even being on. I remember this problem happening only after the entire cabin was dynamated, any other id
