P2A6FAlternative Fuel Rail Pressure Regulator Inlet Pressure Too High

P2A6F indicates that the powertrain control module has detected an inlet pressure at the alternative fuel rail pressure regulator that is higher than the expected range for the current operating conditions. The computer compares the measured inlet pressure from a dedicated sensor against a calibrated threshold and sets this code when the reading stays above that limit long enough to be considered a hard fault.
