Hva betyr feilkoden?
The code concerns the coolant circuit temperature sensor, and the condition is that the signal wire to the sensor is shorted or has a break. Although the code is named low, it is the wire that counts, and the engine control module checks that the sensor signal is reasonable.
Mulige årsaker
- Damaged temperature sensor
- Short circuit or break in the wiring to the temperature sensor
Hva du kan gjøre
- 1Read off the fault code status with the ignition on and check whether it is still active
- 2Check that the fuses are intact. The locations are shown in the instruction manual or on the fuse list
- 3If you have a diagnostic tool, check in live data that the coolant circuit temperature changes sensibly while the engine runs
- 4Have a workshop investigate the temperature sensor. Do not work on the hybrid system's wiring yourself
Symptomer du kan merke3
- The combustion engine is active in HYBRID mode more often than normal, or all the time
- Cooling runs all the time, with the electric cooling fan on
- A message and a warning symbol are shown in the display
