Fault code

Fault storage

Activation of malfunction indicator lamp for engine diagnosis (EURO3/4)

or CHECK ENGINE (MIL)

after the end of the test period and faults

after two successive driving cycles with faults

3

Frequency of the test

continuous

4

Checked signal or status

Limits for coolant temperature/plausibility

5

Fault setting conditions

Lower limit

Upper limit

Plausibility

Fault, if the resistance is greater than approx. 80 kΩ (approx. -39 °C)

Fault, if the resistance is less than approx. 45 Ω (approx. +170 °C)

The increase in temperature after a cold start is compared to a stored temperature model (characteristic). Depending on the start temperature and the engine speed, at least +15 °C must be reached after approx. 120 - 1200 s.

6

In the event of a fault, driving continues at a substitute value from the temperature model. If the signal becomes plausible again, the system changes over to the signal from the coolant temperature sensor.
