Co oznacza ten kod błędu?
The CPM has logged an excessive temperature gap between the overheat thermostat and the sensor. The heater is then deactivated and the code is set. The cause may be air or a leak in the cooling system, a damaged water pump, a damaged coolant temperature sensor or a damaged overheat protection thermostat.
Możliwe przyczyny
- Air or leakage in the cooling system
- Damaged water pump
- Damaged coolant temperature sensor
- Damaged overheat protection thermostat
Co możesz zrobić
- 1Check that the cooling system does not leak and that there is no air in it
- 2If you have a diagnostic tool, activate the water pump; if it does not start, the fault is probably permanent, while a pump that starts points to a temporary fault
- 3Check that the temperatures at the thermostat and the sensor roughly agree once the engine is warm
- 4If the fault returns, have a workshop measure the thermostat resistance and replace it if needed
Objawy, które możesz zauważyć1
- The parking heater does not work
Na co może wpływać usterka2
- The heater is deactivated when the code is set
- If the heater is activated again, it makes a new start attempt
