Hey guys I was wondering if any of you could help me I have a check engine light on for code P04DB any ideas what that is? And is it anything serious? Thank you

I struggled with this code. Long story short bigger tires caused the transmission to let the engine lug. What year truck? What modifications If any? How many miles?

I have been seeing online about the crankcase venation?

check your tube coming off the ccv sensor, it’s on the front drivers side of the engine. Sometimes they can rattle around and develop play in the o ring

Do you have a picture of what this looks like? Or anything that might help thank you
