What are the characteristics of the coolant temperature sensor?

[IkerAnn]

Coolant temperature sensors generally have identical characteristics to intake air temperature sensors. The coolant temperature sensor is typically installed on the cylinder block or at the outlet of the water jacket. The structure and circuit of the coolant temperature sensor operate on the same principle as the intake air temperature sensor. The functions of the coolant temperature sensor are as follows: 1. Water temperature. The temperature of the coolant is the primary parameter monitored by this sensor. The vehicle's sensor is highly sensitive and can detect various conditions, such as incorrect ignition timing, excessively high coolant temperature, or fan malfunctions, and can alert the driver. 2. Prevention. It not only detects problems but also helps prevent them. This primarily involves monitoring the coolant temperature, which is displayed on the vehicle's dashboard, allowing the driver to observe it directly and identify any anomalies promptly. This prevents the car's radiator from overheating and boiling. Additionally, it emits an audible warning when the temperature is too high.
