Posted to the Waveform Library on 5/17/2013

Screen shot of O2 sensors pegged rich and PCM does not decrease fuel trims to compensate despite Closed Loop. Due to defective Fuel Tank Pressure Sensor. Verify by disconnecting the FTPS at the 6 pin (C436 Pink/Red wire)connector above fuel filter. Fuel control returned. MIL on for OPEN sensor confirmed PCM ability to recognize and store code.
