Limits for coolant temperature signal |

Fault setting conditions |
|
| |
Lower limit value |
Fault if resistance greater than about 80 kΩ (ca. -39°C). |
| |
Upper limit value |
Fault if resistance less than about 45 kΩ (ca. +170°C). |

In the event of a fault, driving can continue using a substitute value from the temperature model. The system will then change back over to the signal from the coolant temperature sensor once the signal becomes plausible again. |
