Which sensor is used to determine the temperature of the engine?
A coolant temperature sensor (CTS) (also known as an ECT sensor or ECTS (engine coolant temperature sensor) is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off.
How do engine temperature sensors work?
The sensor works by measuring the temperature that’s being given off by the thermostat and/or the coolant itself. The temperature is then sent to the on-board control system. As the control system receives the temperature from the CTS, it may trigger the cooling fan to either shut off or turn on.
What are the types of temperature sensors?
There are four types of temperature sensors that are most commonly used in modern-day electronics: thermocouples, RTDs (resistance temperature detectors), thermistors, and semiconductor based integrated circuits (IC).
How can I test the coolant temperature sensor?
Testing the ECT/CHT sensor Resistance: One way is to measure the resistance of the sensor at different engine temperatures and compare the readings to the specifications listed in the service manual. Measuring the resistance of the Engine coolant temperature (ECT) sensor.
Where is the temperature sensor on a truck?
The location of your vehicle’s temperature sensor may vary depending on your make and model, but generally, it’s located next to your thermostat on your engine block. If you’re working on a truck with a large engine, the thermostat may be located behind the metal cylinder on top of the engine block known as the intake plenum.
How does the cylinder head temperature sensor work?
Some cars use a cylinder head temperature or CHT sensor instead of, or in addition to the ECT sensor. The CHT sensor (see the photo) works the same way, but it measures the temperature of the cylinder head metal and is not immersed in coolant. This allows the CHT sensor to measure the temperature of the engine correctly even with loss of coolant.
What happens if the engine temperature sensor fails?
In most cases, the engine temperature sensor fails due to corrosion. This is because of its exposure to engine coolant. It may also fail if the coolant leaks through its wiring connector. What to do if the engine temperature sensor fails?
Where is the engine temperature sensor located?
Engine Coolant Temperature sensor is primarily located in the coolant passage of the liquid cooled engine; typically near the thermostat valve. The position of the engine temperature sensor. The engine temperature sensor connects either to the temperature gauge or to the temperature indicator in the dashboard.
What are the symptoms of a bad temperature sensor sensor?
- Decrease Fuel Mileage. The temperature sensor is responsible for sending feedback information to the computer at specific resistances which will vary the engines power output causing the fuel mileage
- Check Engine Light. A cars computer is capable of reading the values of any sensor at any given time.
- Engine Will Overheat.
How does engine coolant temperature sensor work?
The tip of the coolant temperature sensor is generally located near the coolant of the engine. This temperature sensor works by measuring the temperature that the thermostat or coolant is giving off. The temperature that the sensor reads is then sent to the onboard computer or engine control system as a signal.
What is the function of a temperature sensor?
A temperature sensor is a device that gathers data concerning the temperature from a source and converts it to a form that can be understood either by an observer or another device. These sensors come in many different forms and are used for a wide variety of purposes, from simple home use to extremely accurate…
