    codes coming up in 02' wrx

    Finally got my obd2 scanner in today to run a check on my car. Here's what codes came up, any help as to what would fix these codes would be great, I've been unable to find any solutions. I bought the scanner because of a low rpm misfire I'm having


    Stored codes
    P0122, P1130, P1139, P1507, P1560

    An electric fault would explain everything. So charging system / electrics / battery fault would explain it all and would be simpler to envision. Start there. If you've done something to the electrics or electronics, that's the answer. Fix what you've done and reset the ECU and see what happens. If something is faulty with the electrics, start there.

    If not, deal with P1560 first would be my guess -- but only a guess:

    P1560 means the ECU is not receiving current from the battery when the car is off. This implies that every time you start the car the ECU thinks you've just connected a fresh battery, so you are not accumulating any learned data.

    Check all the fuses, particularly the fuses in the engine compartment. Look for fuse SBF-5 specifically.

    Turn the ignition off and measure V between the ECU and ground. If V is >10 V, repair contact in ECU connector. The wire you are looking for is no. 10 on connector B137. As you hold B137 with the two slider tabs and central tab facing up, no. 10 is the wire in the middle row at the far left.

    Next check the resistance between that same wire and ground. If less than 10 Ω, find and fix a ground fault.

    If fuse SBF-5 is blown, it's either a fluke (unlikely but fathomable) or (a) an open circuit between the ECU and battery; (b) poor contact at the ECU connector or (c) poor contact at battery.

    Reset the ECU after all that.

    Hope this helps.

    Disclaimer: If you blow up your car following or misfollowing or considering or ignoring these suggestions, you get to fix the car at your cost. Be safe.

    Is your battery almost dead?

    Any mods to the car?

    No the battery seems to be fine. Only mods to the car are exhaust and aftermarket BOV. Could any of those codes being thrown be what is causing my misfire as well?
