Cel code P04F0

Anyone had this issue? I’ve cleared code and it comes back on, can’t really figure it out. When it cleared it only happens when I lay into the gas

I have had this same code ever since I installed an aftermarket turbo inlet. I have replaced the purge valve solenoid and the charcoal canister, but it's still on. Same situation as you, clear the code and it comes back on when you lay into the throttle. No drivability/performance issues whatsoever, just annoying to see it.

This comes from the Powertrain - EVAP System High Pressure Purge Line Performance so you may have a leak.

Thanks! That was the next step I'm going to take, check all the lines, however at this point, I believe it is the one that is connected to the turbo inlet.

It looks like it is related to a sensor.

Also have a look on this link and the pdf files found in there.
