2007 PT Cruiser p0452 code

Question

no code appeared until car battery died, now p0452 code appears. Can this be due to low voltage from battery?

Answer 1

HI there,

This code is for low voltage at the evap system pressure sensor. This is not likely a result of a dead battery but some type of evap system issue. That being said, I would clear the codes, then see if this code returns. If it does, then you will need to check the evap system for leaks.
