Was bedeutet der Fehlercode?

During engine warm-up the ECM compares how the temperature rises with the increase it expects, calculated from factors such as load and starting temperature. The code is set when the engine temperature reading is too far from the calculated value. The fault may lie in the sensor, its wiring or the thermostat.

Mögliche Ursachen

Contact resistance or oxidation in the wiring and connectors to the engine temperature sensor
Signal wire in contact with ground
Signal wire in contact with supply voltage
Damaged thermostat
Damaged coolant temperature sensor

Was Sie tun können

1Read the codes in the engine control module and note whether any other fault codes are present
2Check the connector and wiring to the coolant temperature sensor for oxidation, loose contacts and chafing
3If you have a diagnostic tool, follow the coolant temperature in live data while the engine warms up and check that it rises smoothly
4Check that the fuses are intact
5Use a multimeter to check that the signal wire to the temperature sensor has no contact with ground or supply voltage
6If the fault returns, have a workshop with diagnostic equipment check the sensor and the thermostat
