20e120 code help??
I installed my downpipe and of course I am getting CEL for the cat code. I'm also getting a new code I never saw before.
Code 20E120 - Crankcase Ventilation, vent hose: not connected/faulty. Even after installing my silicone intake boot and new turbo inlet I didn't get this code. I checked all connections and they are snug, so I am a little stumped here. Still running stock airbox just with a K&N filter. Any tips?  View post on imgur.com |
