What Is an Emissions System?
The emissions system works to reduce the harmful pollutants that are the by-products of your engine’s combustion process. Your car is equipped with a series of sensors that measure everything from the temperature of the air coming into the engine, to the percentage of unburned fuel in the exhaust. Those sensors feed that data to the car’s computer, which continually makes adjustments to the fuel mixture in an effort to produce less pollution from the engine. Most notably is the oxygen sensor (or O2 sensor), which measures the percentage of oxygen in the exhaust to tell the computer whether or not to send a higher or lower volume of fuel into the engine.
From time to time, these sensors may malfunction, and on rare occasions, the computer itself will fail, needing replacement.
The emissions system also includes a mechanism for capturing fuel vapors so they do not enter the atmosphere. This system contains a series of vacuum hoses as well as a charcoal canister, which can both require service from time to time.
