What is resistance reading on a coolant temp sensor for cumputer?

The resistance reading on a coolant temperature sensor typically varies depending on the temperature of the coolant. For most temperature sensors, such as thermistors, the resistance decreases as the temperature increases. Common resistance values can range from a few hundred ohms at low temperatures (e.g., 20°C) to several thousand ohms at higher temperatures (e.g., 100°C). It's important to consult the specific vehicle service manual for the exact resistance specifications for the coolant temperature sensor in question.
