    COBB not autoclearing code 2c9f

    Hi,

    I have S2+ installed on my car, but im still getting the code 2c9f lambda probe fault code after cats, despite having the S2 on my car with autoclear.
    I have no cats, what can be the problem??

    Thanks

    We don't touch the 2C9F code as that's a heater signal issue. Sounds like you have a bad/damaged O2 sensor or you possibly you swapped the sensors during install (front to rear).
