Restore parameters PR063 Fuel temperature and PR064 Coolant temperature.
Fuel temperature reference value when operating at idle speed is between 60 °C and 80 °C.
The coolant temperature reference value is between 80 °C and 90 °C.
Note:
– when the fuel temperature is above 120°C, the maximum rail pressure is reduced to protect the plastic pipes,
– when the coolant temperature is above 100°C, the maximum rail pressure is reduced to protect the engine.
Are the fuel and coolant temperatures within the
reference value range?
YES
NOCheck the coolant temperature (see the
interpretation of DF001 Coolant
temperature sensor circuit) and fuel
temperature sensors (see the
interpretation of DF098 Fuel temperature
sensor circuit).
