Hva betyr feilkoden?
The ECM has registered that the signal from the coolant temperature sensor is faulty. The fault can come from poor contact in the sensor connector or from a damaged sensor. A thermostat that is not working properly can also set the code.
Mulige årsaker
- Contact resistance in the sensor connector
- Defective thermostat
- Damaged engine coolant temperature sensor
Hva du kan gjøre
- 1Read and clear the fault code and check whether it returns
- 2Check the coolant temperature sensor connector for play, contact resistance and oxidation
- 3If you have a diagnostic tool, read the engine coolant temperature in live data and check that it rises sensibly during warm-up
- 4Check that the thermostat opens as the engine warms up
- 5Have a workshop replace the coolant temperature sensor if the fault remains
Symptomer du kan merke5
- The engine is difficult to start when warm
- Driveability problems during warm-up
- The cooling fan can keep running with the ignition off
- The malfunction indicator lamp (MIL) is lit
- Uneven idle
Hva feilen kan påvirke2
- The engine cooling fan runs at low speed
- The engine cooling fan is activated at a predefined speed
