However, some vehicles dispense with the need for two temperature sensors by using just one sensor to do both tasks. There may be two temperature sensors in some vehicles, one to send information from the engine system to the control unit and another from the control unit to the dashboard.

However, it is usually in close proximity of the thermostat of the cooling system, or inside it.

Where to Find the Coolant Temperature Sensorĭifferent 2007 Dodge Caliber manufacturers install the coolant temperature sensor differently. By this continuous monitoring of coolant resistance (and the voltage output), the coolant temperature sensor sends temperature information to the2007 Dodge Caliber s engine control unit. This voltage output is sent to the electronic control unit of the vehicle, which constantly measures the resistance across the2007 Dodge Caliber s coolant. As the temperature rises, the resistance of the2007 Dodge Caliber s coolant drops and this in turn decreases the potential difference output. The temperature of a thermistor influences its resistance in an inverse proportion. Thus, principally, the coolant temperature sensor is a thermistor. As the temperature of the engine changes, the potential difference output of the device also changes, and this can be measured by the engine's control unit. This device works on the principle of dependence of potential difference in temperature. The Coolant Temperature Sensor's Function , abbreviated as CTS, in your 2007 Dodge Caliber is an important device that enables the control unit to give alerts if the engine is overheating or if the temperature within the system is rising for some reason.
