This DTC is stored if the fuel pressure sensor (for high pressure side) output voltage is out of the standard range due to an open or short in the sensor circuit.
Example:
If the fuel pressure sensor (for high pressure side) output voltage is higher than 4.9 V for 3 seconds or more, the ECM will illuminate the MIL and store this DTC.
