What is the purpose of coolant temp sending unit?

The coolant temperature sending unit monitors the temperature level of coolant in the engine to decide when the engine has reached operating temperature. Once the engine has warmed up enough, the sensor sends a signal to the ECU, which then knows to activate its other sensors to monitor the engine and exhaust systems.

What does the temperature sending unit do?

by K.K. Lowell. The temperature sending unit, more properly known as a temperature sensor, is one of the most important sensors in your car. It is the sensor that tells the computer when the engine has warmed up sufficiently for the computer to pay attention to the many other sensors on the engine and exhaust.

Where is the temp sending unit?
