temperature sensor to help determine the proper amount of fuel and how long to open the fuel injectors. The ECU also uses this data to determine how much the ignition timing should be advanced as well as the proper setting for the ISC to maintain the proper idle speed. When either the air temperature or the coolant temperature is low, the respective thermistor's resistance increases and the ...

What is an In-Car Temperature Sensor?

The In-Car Temperature sensor (ICTS) is a negative temperature coefficient sensor. It senses the air temperature of the passenger compartment, and the ambient temperature sensor (ATS) senses the air temperature outside of the vehicle. The EATC compares these values and makes output decisions based on the difference between these air temperatures.

Inside a Car – Coolant Temperature Sensors

The coolant temperature sensor is fastened to the intake manifold of an engine coolant and is often referred to as a negative temperature coefficient type of sensor. In terms of resistance capacity, this coolant sensor has 20,000 ohms at 248 degrees Fahrenheit. There is an inverse relationship between the electrical resistance and the engine coolant ( when the engine coolant temperature ...

They are the fuel and air temperature sensors. A car fuel temperature sensor monitors how hot or cold the fuel going to the engine is. Warm fuel burns faster, which means a more efficient engine. Cold fuel is denser and doesn’t combust as efficiently. The intake air temperature sensor, IAT, measures the temperature of the air entering the engine.

What is an In-Car Temperature Sensor?

In-Cabin Temperature Sensor. The in-cabin or in-car temperature sensor is an (NTC), negative temperature coefficient sensor. This means that as temperature increases, resistance in the sensor decreases. Its signal voltage varies between 0 and 5 volts. The electronic automatic temperature control system's microprocessor uses this, along with the ambient temperature and sun load sensors …
