Everything to Know About Your Car's Oxygen Sensors

If you own a modern vehicle, it most definitely has oxygen (O2) sensors in the exhaust system. These sensors perform the necessary function of monitoring the amount of oxygen running through the engine. The sensor itself is connected directly to the vehicle's computer system. If the sensors pick up too low or too high of oxygen, the sensor will trigger your check engine light to come on. 

Relation to the Check Engine Light

Oxygen sensors are one of the many common reasons your check engine light might come up on your dashboard. In the case that it relates to your O2 sensors, the warning light may just be a warning to get the oxygen sensor replaced. When the oxygen levels are off in your engine, it is a cause for significant concern. Either way, an experienced mechanic can run a diagnostic and confirm whether your check engine light is signaling an O2 sensor problem.

Where Are the Oxygen Sensors Located?

Most vehicles will hold multiple oxygen sensors in their exhaust system; the most basic model has one in the catalytic converter and one in each of your exhaust manifolds. Newer cars will include a minimum of four oxygen sensors along with many other sensors that your car may have.
