    Angry P0139 CEL with Accessport????

    I have catless Helix DP and tsudo catback. I have had the P0139 for a few thousand miles, i unhooked the battery, but just came back. When i look up the CEL lights from the AP, it shows no trouble codes found. But i still have the light.

    Any idea?

    1. Check the version of the map you are using. If it is older, it may not have the CEL defeat for P0139.
    2. The CEL defeat for the AP only works when installed as a base map. If it is a real-time map, it won't defeat the CEL.

    Go from there.
