2008 Dodge Ram 1500 CEL light came on, error code P0404

Question

I’m about drive across the country to handle some family affairs in another state, but CEL light came on. I checked the code and it was P0404 which is problems with the EGR valve. It took it out to check for carbon build up and there wasn’t any, so I put it back and reset the CEL light hoping it’d go away. It came back after about a day. I’m wondering if I should address this before I hit the road or if it’s something that can wait till after.

Answer 1

It's likely a bad EGR. I'd throw one on right quick if you can. In a pinch, you can drive it that way. It might idle rough and get worse mpg. But it'll survive.

Thanks I’ll try and replace it quickly.
