Tridon Coolant Temperature Sensor TCS114

A coolant temperature sensor in a car is a crucial component that monitors the temperature of the engine coolant. It is typically located in the engine block or near the thermostat housing. The sensor works by continuously measuring the temperature of the coolant and sending this information to the car's Engine Control Unit (ECU) or Powertrain Control Module (PCM). This data is then used by the ECU/PCM to make necessary adjustments to manage engine performance and assist in maintaining optimal operating conditions.

The coolant temperature sensor provides vital information to the vehicle's computer system, allowing it to regulate fuel injection, ignition timing, and engine cooling fan operation. It helps prevent the engine from overheating or running too cold by adjusting the fuel-to-air mixture and ensuring optimum delivery of fuel for combustion. Additionally, the sensor is instrumental in activating the cooling fan when the coolant temperature rises above a certain threshold, effectively cooling the radiator and preventing any damage to the engine. In summary, the coolant temperature sensor plays a crucial role in maintaining engine efficiency, performance, and preventing potential engine damage.
