A 2 wire temp sensor is an important device for controlling the temperature of a variety of automotive systems. It is used to measure the temperature of the coolant in a vehicle’s cooling system and provide feedback to the engine control unit (ECU) so that it can adjust the amount of fuel and air being delivered to the engine. A 2 wire temp sensor is also used to monitor the temperature of air conditioning systems, air intake systems, and other components.
How Does a 2 Wire Temp Sensor Work?
A 2 wire temp sensor works by sending a signal to the ECU when the temperature of the coolant exceeds a predetermined level. This signal triggers the ECU to adjust the fuel and air flow to the engine, thus maintaining a safe temperature for the engine and its components. The 2 wire temp sensor is designed to be robust and reliable, with a long service life. Each 2 wire temp sensor is also equipped with a ground wire, which is used to ensure proper grounding of the device.
