EGT Sensor

EGT sensor is a component that helps optimize the operating conditions of the engine by measuring the exhaust gas temperature. Exhaust gases coming out of the combustion chamber are an important parameter that shows how efficiently the engine works. EGT sensor measures these temperatures and sends data to the engine control unit (ECU). In line with this data, the ECU ensures a more balanced operation of the engine by adjusting the fuel injection timing and air-fuel mixture. Especially in turbocharged engines, the EGT sensor plays a critical role in preventing damage to the turbocharger and other components due to excessive temperatures. data-start="1605" data-end="1629">EGT sensor prices vary depending on the material quality used, measurement sensitivity and connection type. There are different quality sensors in the market, original and aftermarket. While original EGT sensor prices may be higher, aftermarket products are more affordable but may not last as long as the originals in terms of durability. EGT sensor prices suitable for the brand and model of the vehicle may also vary depending on heat resistance and signal sensitivity. Engine performance is directly affected by this component, so it is important that this component is high quality and reliable, so well-known brands should be preferred instead of very low priced products.

How Does an EGT Sensor Work?

EGT sensor is a temperature measuring device that works on the thermocouple principle. The thermocouple consists of a combination of two different metals and produces voltage as a result of temperature changes. EGT sensor measures the temperature of the exhaust gases and transmits this voltage to the engine control unit. The ECU evaluates this data and adjusts parameters such as fuel injection, turbo pressure and air-fuel ratio. If the EGT sensor does not work correctly, the engine temperature may be detected incorrectly and thus combustion efficiency may be negatively affected. Therefore, it should be checked at regular intervals whether the sensor is working correctly or not.

Why is the EGT Sensor Important? sensoris of great importance for the safety and performance of the engine. The temperature of the exhaust gases is a critical factor in determining whether the engine is overheating. Thanks to EGT sensor, overheating of the engine is prevented and possible malfunctions are prevented. In turbo engines, high exhaust temperatures can shorten the life of the turbocharger and reduce the overall performance of the engine. EGT sensor prevents such negativities and ensures longer life and efficient operation of the engine. Especially in modified engines, the use of EGT sensor is a critical requirement to prevent damage to the engine.

How to Detect EGT Sensor Failure?

EGT sensor malfunction may manifest itself with symptoms such as decrease in engine operating performance, increase in fuel consumption and abnormal changes in exhaust gas temperature. When the EGT sensor is broken, the engine control unit may receive incorrect temperature data and, accordingly, the operating conditions of the engine may be adversely affected. While extremely high temperatures can damage engine components, low temperatures can cause the engine to operate inefficiently. When the EGT sensor fails, symptoms such as sudden performance decreases in the vehicle, engine light on and increased fuel consumption may occur.

EGT Sensor Maintenance and Replacement

EGT sensor maintenance should be performed at regular intervals to maintain healthy engine operation. Since it is located within the exhaust system, the sensor may measure inaccurate data over time due to soot and carbon accumulation. EGT sensor can be cleaned or replaced when necessary to ensure efficient engine operation. Replacement should not be neglected, as a faulty sensor will cause the engine to operate incorrectly. The replacement process is usually simple and is completed by removing the old EGT sensor connected to the exhaust manifold and replacing it with a new one.

Where is the EGT Sensor Located?

EGT sensor can be positioned before the exhaust manifold, turbo inlet and outlet ports or DPF (Diesel Particulate Filter). It can be placed in different locations to best monitor the temperature balance of the engine. In turbo engines, it is usually located at the turbo inlet or outlet, while in naturally aspirated engines it is mounted on the exhaust manifold. In diesel engines, it is usually located before the particle filter and monitors temperature changes. EGT sensor must be positioned correctly to ensure healthy operation of the engine and exhaust system.

Advantages of Using EGT Sensor

EGT sensor is an important component that increases performance by optimizing engine temperature management. High temperatures may cause engine wear and parts damage. Thanks to EGT sensor, the temperature is kept under control and the engine operates efficiently. It also helps the engine produce more power safely by preventing high temperatures in modified vehicles. EGT sensor optimizes fuel consumption, reduces carbon accumulation and ensures longer life of the exhaust system.

What to Consider When Buying an EGT Sensor?

When purchasing an EGT sensor, the vehicle's engine type, turbocharger status and sensor connection points should be taken into consideration. In order to make accurate measurements, sensors containing high-quality thermocouples should be preferred. EGT sensor must be resistant to high temperatures and suitable for long-term use. Poor quality sensors may cause incorrect temperature measurements, causing engine damage. EGT sensor models recommended by the original equipment manufacturer (OEM) of the vehicle should be preferred.

In line with this detailed information, EGT sensor You can maintain the performance of the vehicle and extend the engine life by acting consciously about its use, maintenance and selection.
