The module also monitors itself for internal faults and will set code P0606 if it detects an internal error.<\/p>\n\n\n\n<p>If you get code P0606 and you haven&rsquo;t installed any components of questionable quality that might have caused the code, you&rsquo;re likely to need a replacement PCM\/ECM, which will need to be flash-programmed in almost every case on modern vehicles.
