    Throwing CEL with AP stage 2

    So I have an 06 STI. Full tbe, cobb shortram and ap stage 2 ots map. For the first 6 mos I threw only 1 cel, no biggie. Now, every time I get on it and there is any wheelspin whatsoever, I throw a cel with the same 6codes. P0502, p0503, p1152, p1153, p158 and p0851. I just uninstalled the AP and sofar, no cel.... I read in another post it could possibly be a bad speedo gear in the tranny or something like that? It's wierd because when I drive normal or even a little aggressive with the stage 2 map, it doesn't trip the CEL, but as soon as I get on it and the wheels spin (like going around a corner), bam. Also, it has a flashing cruise light while the cel is on. Any ideas??

    this looks a lot like the green connectors are still connected after flashing the Cobb map. Are you sure they are totally disconnected? Since this only happens when you get wheel spin, this should not be the problem but with this many codes and a flashing CEL, thought I'd toss it in.

    2 wheel speed sensors codes (high and low), 2 netural switch codes (high and low), and two O2 sensor codes (high and low)... thats crazy... could be a fault in the map if it only happens with the stage 2 map...

    I would have to agree. Have you tried a different map?

    I did some more research on this and I have not been able to find this specific set of codes other than when the plugs are still connected (and you get more than this with that situation).

    I've tried both the anc 91 hwg and anc91 regular maps, same on both.... I uninstalled the AP on my way o work this morning, I will drive around and see if I can get a cel without it installed... Going to get protuned soon, hopefully that alleviates the situation if it is something to do with the AP maps
