Have you heard of the terms O2 sensor, lambda probe, lambda sensor, lambda sound or how about EGO which stands for exhaust gas oxygen sensor? These terms are used synonymously with the term oxygen sensor. For most car owners, it would be impossible to be familiarized with the different car parts considering their huge number, and that is why mechanics do take charge every time a problem is encountered with any of these parts. The oxygen sensor is among the very rare car parts that is subjected to malfunctions, however should you come across with a problem with this part and you need to replace it, better take note of these details.

Oxygen sensors including those of the Mercedes Benz’s are hollow tube devices inserted into the exhaust manifold. This tube is divided into two compartments (the inner and the outer) by U-shaped rod coated platinum for the purpose of measuring the volume of oxygen remaining in the exhaust gas and allows an electronic system called electric control unit or ECU, to control the efficiency of the engine’s combustion process. This whole process helps in keeping the engine in perfect and tip-top condition.

Furthermore, an oxygen sensor works whenever the exhaust gas enters the outer compartment through a series of slits, and air is made available to the inner compartment through a vent at one end. In the event that this process takes place, an electrical signal is produced by the platinum as a reaction to the difference in oxygen content on either end of the rod, thus the said signal lets the computer know how much oxygen is in the exhaust and the computer will now tell how well the fuel is burning. The driver or the owner will now know if his car’s engine is still working properly, and can give immediate attention when necessary.

Basically, oxygen sensors are not solely used in automotive applications to measure the performance of internal combustion engines in automobiles and other vehicles, but also in other applications such as divers using it to measure the level of oxygen they are breathing, and scientists using to measure respiration and production of oxygen. Nonetheless, oxygen sensors are widely and commonly used in automotive applications that is why, here at Parts Train, we offer the best quality of oxygen sensors you will need especially for your Mercedes Benz automobiles. We guarantee your optimum satisfaction upon trying and testing our products.
