I have an 2006 Hyundai Sonata and it failed inspection for a window sticker. The code is P0452 and do not know what it means. Can someone tell me what needs to be fixed and what is the error code meaning?
It means the engine computer doesn't like the signal it's getting from the fuel tank pressure sensor. There are a few possible reasons why the signal could be wrong. You'll need to have the fault diagnosed to figure it out.
