Coolant Temperature Sensor

A coolant temperature sensor is an electronic device that monitors the temperature of the engine coolant and sends this information to the engine control unit (ECU). This sensor is usually located near the engine thermostat or in the engine block. The coolant temperature sensor is crucial for ensuring that the engine runs at the optimal temperature. If the engine gets too hot or too cold, it can cause damage to the engine and decrease its performance. The ECU uses the data from the coolant temperature sensor to adjust the fuel injection and ignition timing to maintain the correct engine temperature. If the coolant temperature sensor fails, it can cause engine overheating, poor fuel economy, and reduced engine power. Regular maintenance of the coolant temperature sensor is essential for ensuring that the engine runs smoothly and efficiently.
