If you own a vehicle that was produced after 1980, it will definitely include oxygen (O 2 ) sensors in the exhaust. Some vehicles from earlier than that will also have them. These sensors perform a vital function and are connected directly to the car’s computer system. They monitor the relative amount of oxygen running through the engine. If the oxygen levels are too low or too high, the sensor will be tripped and your check engine light will come on.
What Do Oxygen Sensors Do?
Oxygen sensors are one of the most common reasons why the check engine light comes on. Yes, they can wear out and/or simply fail over time. In other words, the warning light may just be a result of an oxygen sensor that needs to be replaced. Or, the sensor may be doing exactly what it is supposed to be doing. In this case, the check engine light is on because the oxygen levels are off in your engine and it’s cause for significant concern. Either way, a good mechanic will be able to help you determine the source of the problem and make the necessary repairs.
Oxygen Sensors and Colorado Emissions Standards
With emissions standards ever increasing here in Colorado, it’s important to have properly functioning oxygen sensors. If one in your vehicle is not working correctly, you will not pass a smog inspection. They are placed in strategic spots within your exhaust system. This makes sure that the engine is running with the optimal oxygen levels. The information being sent to the car’s computer from these sensors allows it to self-calibrate the engine for better performance and fuel efficiency.
Where Are the Oxygen Sensors Located?
Most vehicles will contain multiple oxygen sensors, with the basic set-up requiring one in front of the catalytic converter and one in each of the exhaust manifolds. Modern vehicles produced in the past 20 years will feature at least four oxygen sensors along with many other strategically placed sensors throughout the vehicle monitoring the various systems.
