Hva betyr feilkoden?
The CPM has logged repeated overheating of the heater, several times in a row, which sets the code. The fault can be caused by a damaged sensor, thermostat or water pump, or by air or a leak in the cooling system.
Mulige årsaker
- Damaged coolant temperature sensor
- Damaged overheat protection thermostat
- Air or leakage in the cooling system
- Damaged water pump
Hva du kan gjøre
- 1Check the coolant hoses for damage and leaks, and look for air in the system
- 2If you have a diagnostic tool, activate the water pump and listen for a buzzing sound; if there is none, the pump is suspect
- 3If you have a diagnostic tool, read the temperatures at the overheat protection thermostat and the coolant temperature sensor and see whether one differs strongly from the other
- 4Clear the code and check whether it returns when the ignition is switched on
- 5If the fault returns, have a workshop test the thermostat, the sensor and the water pump with measurements
