Chrysler Sebring Coolant Temperature Sensor
About Coolant Temperature Sensor
An engine should be running at an optimal temperature most of the time for it to prevent the problems caused by overheating. This is taken care by the engine coolant, which absorbs the heat given out by the engine thus maintaining the required optimal temperature. Without the coolant running around the engine through the coolant jackets, the engine would overheat in no time and could even cause the pistons to be welded against the cylinder wall seizing the engine. Hence the coolant temperature sensor prevents this from happening by constantly monitoring the coolant temperature indicating the heat given by the engine.
What is the purpose of Coolant Temperature Sensor?
The coolant temperature sensor,powered by the ECU measures the coolant temperature in real time and gives this data to the ECU. The ECU processes the received data and adjusts the fuel injection, ignition timing and also controls the radiator fan.
How Coolant Temperature Sensor Works?
The coolant temperature sensor is is immersed in the coolant and measures the temperature. This sensor is a temperature variable resistor with a negative coefficient. This means, the resistance decreases with the increase in temperature. This is the most commonly used type in the vehicles. The predecessor of this sensor was a positive coefficient type where the resistance increases with increase in temperature. The sensor translates this resistance variation to voltage variation which is further processed by the ECU as coolant temperature.
Where is Coolant Temperature Sensor Located?
The sensor is located in a coolant passage and sits right before the thermostat. This can vary from vehicle to vehicle but it is the place where the sensor is most commonly found.
