It is a two-wire thermistor immersed in coolant and measures its temperature.Click to see full answer. In this way, how do I know if my coolant temp sensor is bad? Signs of a bad Engine Coolant Temperature Sensor Poor Mileage. Check Engine Light Activates. Black Smoke from the Exhaust pipe. Engine Overheats. Poor Idling. Do not Use Tap Water to Refill Radiator. Fix Oil Leaks and Gasket Immediately. Check for Coolant Leaks. One may also ask, how do coolant temp sensors work? The sensor works by measuring the temperature that’s being given off by the thermostat and/or the coolant itself. From there, your vehicle’s computer will use this temperature information to either continue operating or adjust certain engine functions, always working to keep the engine temperature at an ideal level. Similarly, it is asked, what is the coolant temperature sensor? The coolant temperature sensor, also known as the coolant temperature switch, is an engine management system sensor that is used to monitor the temperature of the engine’s coolant. Most coolant temperature sensors operate using electrical resistance to measure the temperature of the coolant.What kind of resistor is an engine coolant temperature ECT sensor?The Engine Coolant Temperature (ECT) sensor is a thermistor (a resistor which changes value based on temperature) mounted in the engine coolant stream. Low coolant temperature produces a high resistance (100,000 ohms at -40°F.)
