I have a 2016 F150 3.5 l ecoboost and installed an AEM cold air intake and had the same problem with the P04DB code. I ordered and installed the latest Dual Catch Can system from UPR with the VPS sensor which prevents the code from coming on. So far so good. It's been on a month and working well. If the code comes on again UPR said they would recommend a custom tune to permanently disable it. I'm hoping for free.

P04db code
hopefully you you have the latest catch can system with the code fix in it by UPR. By any chance do you have a cold air intake system installed and if so what brand?

p04db code
After weeks of trouble shooting the situation it turned it to be my cold air intake that was popping the code. AEM sent me out a 6 inch aluminum tube that gets inserted into one of the hoses for the air intake. (Which came with instructions). Took literally 10 minutes. I reset the code and never had a problem again. Hopefully this info will help you. Let me know how you make out.

P04db code
AFE has a fix for this code. It's a small aluminum tube about 6 inches long and about as thick as a pencil. It's pointed on a slant on one end, kind of like a hypodermic needle. It comes with instructions and you insert it into one of the hoses coming from the air intake. Once you reset the code you shouldn't have a problem anymore.

Same issue
I am having the same issue with my 2015 3.5, I have the Injen intake and MBRP exhaust kit on it and had no issues. I recently installed the URP catch can kit and now I have the code. It returns every second start up cycle, I also reset the live memory on the truck and so it would hopefully relearn the system but that didnt work. I swapped out the sensor in the kit for the factory one and that didn't work as well. Not sure what to do next.

Thanks in advance for any info you can provide.
