Weird codes after valve cleaning

carlsontheflyer · 06-18-2013, 08:03 PM

As many of you read in my other thread, I had the intake and valves cleaned about a week ago or so. After the nut job was done, the technician cleared all codes and reset the adaptations.

Today I used my Cobb AP to read the codes. I usually check weekly. There are a bunch of H(istorical) codes and 2 strange actives ones I've never heard of.

P2CFB - Choke adaptation value

P2D09 - Throttle control - faulty air (Group error for TPS)

I searched and searched but couldn't find any details on what they mean. Does anyone have any idea?

I got a couple of codes after resetting my throttle adaptations. Probably those two, they should clear after the TPS redapts... I think.

Edit: Mine were 2D09 & 2CFB... so yep.

Edit2: Also after resetting the car does a throttle test where it repeatedly revs, in my case until I cut the engine and restarted.
