I keep having the check engine light come on and the code being the PCM P1415. The dealer is telling me its my modified intake (vortex), but I'm not sure I believe them. anyone have any suggestions what it might be? I checked the vortex and everything is hooked up fine. I even cleaned it and oiled it 3 days ago. Plz help
Hi there,
Your 1415 is for a secondary injection on the drivers side.
As them to check the air injection check valve on the drivers side, and you will see that it is most likely rusted shut.
If your air box was causing the issue, you would see a 0410 or a 1415 and a 1416.
