Hello everyone,
Trying to track down the cause of this error before it starts to cause me any problems. The code is referencing the fuel pressure regulator, but when I look up the info for this car, I don't see a regulator in the fuel system diagrams. Just a pressure sensor in the fuel rail. Am I missing something obvious or should I focus more on the fuel pump/filter? Thanks!

Hey there. Unfortunately I don't really have any more information. In my case the code cleared after running a new tank of gas through it. I don't know if it was a bad tank of gas or the sensor being flaky cause the car had been sitting for a couple weeks before. Sorry I can't be more help.
