I don’t know, it seems like there isn’t a consensus as to whether it is permanent or not. It’s not a check engine light, it’s a triangle with an exclamation mark in it. I’m in Hawai’i for what it’s worth.
I had this very thing happen to me. I bought a bluetooth type OBD2 port scanner but for some reason it won't allow me to clear this code. Can anyone recommend a really good one?
