Rail pressure safety function is not executed
correctly
ECU internal temperature; temperature
measured by ECU is out of the target range
sensed intake air temperature at air filter >
physical high limit

Reset the fault and at reappearance check ECU
and injection system
Close warm air circuits, replace ECU
Check outside conditions:
Temperature > Threshold within the intake air
system of the engine?
E.G: engine sucks in air from hot asphalt out of
paver bucket
Sensor positioned within black air filter housing
above engine lid at hot environmental
conditions and idling or similar?
=> if yes check with application team to adapt
limits
if not check sensor and wiring harness
exchange sensor
