Just figured i'd make a quick post to save anyone else trouble who reads these codes. I can now speak from experience when I tell you that there is no need to plug in the Green Diagnostic connectors under the dash when ONLY attempting to read ECU error codes with the Cobb Accessport. Plugging in these two connectors during diagnostics will cause these 5 codes to appear and you will not be able to accurately diagnose your check engine light. After chasing my tail for the past two days i've finally isolated the one code that is throwing a check engine light on my 05 WRX. Code P0031 (HO2S Heater Circuit Low Input Bank 1-Sensor 1) is what I am left with and tomorrow it will be repaired.
