    P069e check engine code

    I have posted several times in other forums about the code that keeps coming up. Current mods are only the Airaid filter. I have taken the filter off and still received the light. The weird thing the light goes on and off. Took the filter and took it to the dealer. Did not tell them that I had a filter but they could find the problem. Dealer stated the this code usually has another code behind showing what's wrong. Not sure if this is bs or a true fact. No other code behind has ever shown up so dealer states can do anything about it.

    Why in the shop they replaced the supercharger because of the marble noise. They slightly blamed the code on the supercharger. I know that is not why the light is on

    Anybody know about this code and what might be wrong. I am still thinking that the Airaid is causing it but I figure that it would cause a lean code

    Any help would be great

    That code is the FPCM commanding a MIL light. The dealer should be using a scanner that can actually communicate with that module to see the code. Basically the FPCM is recognizing a problem. P069E literally just tells the PCM to throw the light. The dealer is right in that there should be another code. I'm surprised they can't pick one up.
