A faulty sensor can not only affect your miles per gallon, but it can cause break to your catalytic converter and your 2018 Mercedes-Benz CLA 250's spark plugs. The O2 sensor sends data to the vehicle’s onboard computer to represent the decent mixture of air and fuel that enters the cylinders in your engine. A destructive O2 sensor can also cause a car to fail an emissions test.
