Error Code P04DB after installing Injen cold air intake

[JL8jeff]

It's strange that some CAI's (it would be nice to put together a list of known CAI's and people with 23's that actually get the error) get the error and the dual catch cans can cause it. It sure seems like that ccv sensor range is too small and Ford needs to make an adjustment to something. Why is it even needed if the 21-22 were fine?

Edit: After searching around and seeing so many of the ecoboost motors getting this error, it seems like the hall sensor for the ccv is very sensitive with a tight range of readings. I did find that AFE offers an inlet tube for the 3.5 eco cai they sell which has a slash cut to it to help it pull more from the ccv line. That makes me think the cai and the catch can setups are not allowing enough air to be pulled through the ccv line so the computer thinks it's clogged or disconnected. Or one side of the engine is pulling more vacuum to the turbo vs the other and it detects an imbalance. But it doesn't explain why the 21-22 engines don't seem to have the problem.

Exactly! Some emissions BS!

After looking at most of the CAI's for the 2.7, the Injen looks like the only one that goes all the way to the turbo inlet on the driver's side. The others with the driver's side tube only goes to the elbow that has the vent lines. So I wonder if that affects the flow vs the other intakes. It still doesn't explain why 21-22 are ok and why the catch can causes the ccv error with the stock turbo elbow.

They dual catch can causes the code, because the factory tube is replaced with a mishimoto. The fix for that was easy enough. I just took off the catch can on that side and replaced a factory tube. The fix for this cold air intake is not that simple. 🫤

Can anyone with the Injen intake measure the outside diameter of the driver's side tube where I have it circled in yellow. I think it's around 3" but I wanted to verify. I think the stock tube is 2.25". Thanks.

more performance intakes come off then go on these days at the dealer i work for. so many CEL issues.

This is why I won't ever consider an aftermarket intake on a modern vehicle. Too many damn sensors and opportunities for CEL's these days. And I used to install a lot of intakes on my vehicles in the 80's, 90's and early 2000's....without any issues.

same here. remember the cobra's and lightning in the early 2000's picking up 20 whp with just an intake. one 2003 cobra picked up 10 whp by just removing the snorkel that fed the air box.

I have the Injen, the section you circled is 3.18

i have only gotten the issue when it’s relatively cold out. above 60 and never comes in, below 40 and it’s pretty much guaranteed to come in upon startup. between it’s a coin toss. so for me seems to be temperature dependant. tis a 23

Mine also has come on mostly lately when the temperature gets cold but I'm in Wisconsin so it gets cold a lot. And once it comes on I have no way to reset it, It doesn't reset itself. Not sure if you're able to reset it somehow.

Does anyone have pics of the drives side box/section that everyone else leaves in? How restrictive does it appear? Any pics would be appreciated.

Here's a picture of the elbow that connects to the driver's side turbo. This is from the Injen installation guide and it has been disconnected and they are showing how to remove the ccv line which is the end that goes on the turbo. The stock elbow has a 90 degree fitting for the ccv but the Injen has a straight fitting so I wonder if that allows too much flow. It doesn't look overly restricting and it even looks smoother than the rubber bend near the airbox. The K&N, AFE, Mishimoto all leave this elbow in place but run a new tube all the way to it.

 

[Ninjak]

One of the reasons I purchased the Injen was because of how their system removed restrictions the stock system and other systems had. I wonder as well with the 23 models if the change in the sensor is registering to much air? Could that be an issue? The 21 and 22 may have a different sensor, and it compensates for the increased flow perhaps?

Since I have installed the system, I have not had a single code.
