CLAAS 772Fh – Claas Eng A15 Engine Module: Fuel Pressure Sensor Input Voltage Fault

The ENG (A15) engine calculator detects an issue with the input voltage of the fuel pressure sensor in the common rail high. This causes the engine power to be reduced by 20% per minute until it reaches 50% of its nominal power. The engine module is also managing the high pressure pump to maintain 2 000 bar pressure in the common rail.
