Chrysler 300 Oxygen Sensors & Components

An oxygen sensor belongs to devices used by electronic fuel injection systems for real-time monitoring of the combustion process. Although the O2 sensor is often considered as part of emission control devices, it rather belongs to engine control equipment that makes an indirect contribution to the low emissions level – by sourcing the ECU with information about the combustion resultants and thus allowing to improve its quality. As part of the computerized system, the O2 sensor is absent in carbureted vehicles, so you need to worry about it only if your Chrysler 300 is one of the latest-generation cars, which typically use several (at least two) oxygen sensors – before and after the catalyst. The latter checks catalysts' operation.

As oxygen sensors serve the needs of the engine control module, their malfunction will badly affect not only emissions level, but also fuel efficiency and even power, as the fine eco-friendliness of the car is achieved via the high quality of combustion. Therefore, you shouldn’t really hesitate with the replacement of the faulty device. Besides, the purchase of this part won’t be that expensive, especially if you shop in our Chrysler 300 oxygen sensors & components inventory offering lots of quality-built products at reasonable prices.
