What does code P008B mean?

Q: What does code P008B mean?

Low Pressure Fuel System Pressure - Too High. P008B indicates that the powertrain control module has detected a fuel pressure reading in the low-pressure fuel system that is higher than the expected value for the current operating conditions. The computer compares the actual pressure sensor signal against a commanded or modeled pressure and sets this code when the measured pressure exceeds the upper threshold for a calibrated time.
