P04DB Return Code - UPR Dual Catch Can

[tanna786]

Hello,

I'm hoping someone is willing to help me out with this outstanding issue I've been having since last year. It all started all installing the UPR dual catch can- additionally, I have a TurboSmart BOV and tuned by Livernois MotorSport.

I have contacted UPR and they suggested to have Livernois update the tune for the P04DB code and I will be all set. According to UPR, all the Ecoboost platform has this code on the 2015 vehicle with the pressure sensor.

However, Livernois stated this not to be the case and that it's the catch can that's causing the issue.

I have checked all of the connections and they all seem to be intact.

I'm frustrated as my engine light comes and goes anywhere from a week to weeks. I'm afraid it might damage other components or impact performance of the vehicle.

Is there anyone in Southeast Michigan that is willing to get this resolved for me or anyone on the forum who can assist.

Thank you.

is that the positive crank case pressure? I get it on and off all the time with JLT intake, other get it too...might be due to the dual catch can though if it deals with the passenger side crank case vent.

not positive, I was just going by the code and that's what I've been informed. I have the AirAid intake as well. There's got to be a fix out there.

I had that code coming up shortly after I installed the K&N Typhoon intake. I had the Mishimoto catch can installed prior to the intake, with no problems for thousands of miles.

I pulled the K&N intake off (because I honestly lost power with it) and immediately the P04DB went away and never came back.

the port on some of the aftermarket intakes don't seal as tight with the connector coming off the hose and that's been speculated as the reason for getting that code with some of the aftermarket intakes.

All that needs to be done is have the code shut off in the tune. The car complains due to a change in flow which throws the pcv sensor out of ranger when installing larger diameter hoses and different length hoses.

We have that pop up on 2015 F-150 and Mustang.

It is because there is now less crankcase pressure than the factory sensor has been calibrated for. Because the pressure is now less, the sensor see's less voltage which is below threshold.

This code just needs to be disabled by your tuner. If Livernois won't do that for you, then you will be stuck with it.

Less flow = Good.
