Code 122104

Has anyone seen this code 122104 "No Description"
Randomly appears when car is warm.....No description next to code.
It does it at startup during drive at odds....very strange

According to Rheingold the code could be from an open circuit or disconnection for blow-off valve 2. I could check the connector to make sure it isn't loose or doesn't have coolant leaking on it or anything.

My dear friend Matt,

You are a genius! There is a good possibility coolant leak in the area. Cannot wait for day light for visual inspection. Would you have schematic or description on Blow off valve 2 location?

You are the man.....Did you you get your charge pipes by any chance? I am willing to hand you mine...Gratis for friendship and adoration......

Here's the connector circled in red. I would first check if it is loose--that is most likely.

I have not gotten any charge pipes yet, I will be in touch

And regarding Rheingold, I have a download link I will PM you either tonight or tomorrow if you computer dies shortly.
