The code is for a fuel rail pressure being low, but there are a few things that can cause it. Take a look at pic 1. I copied the specifics related to this code. Based on what is listed, it sounds like rather than the sensor isn't the first suspected issue. Also, everything indicates low fuel pressure to the rail and not the result of a bad pressure sensor.
Based on what I am reading, the sensor is most likely working, but the PCM can no longer use the sensor to maintain proper pressure because it is too low.
Did they provide anything that had the pressure readings indicated on it?
