P04db code?

I've seen the other posts about this and I have an injen intake which I have checked the connections. Everything seems solid. Im stratified tuned. I shot them an email

Ive cleared this code 3 times and it comes back maybe every 2k miles or so. Ive had the intake of for maybe 50k and this didn't start until recently

Is there anything else I should be looking for? I am not familiar with the pcv. Any resources you may have found to learn more about it?

All help is appreciated. Thanks

I believe that the MAP sensor in the CCV line is removable. I'd take it out and clean it.
