Although your vehicle's oxygen sensors may not seem like the most exciting aspect of its design, they play a vital role. These devices quietly monitor and optimize your engine's performance. But what exactly do they do, and why should you care about them? Let's explore their significance and how these small sensors can impact everything from fuel efficiency to emissions. What Are Oxygen Sensors and How Do They Work Oxygen sensors, often referred to as O2 sensors, are small electronic devices strategically placed in your vehicle’s exhaust system. Their job? To measure the amount of oxygen in the exhaust gases exiting your engine. When your engine burns fuel, the ideal mix of air and fuel is crucial for efficient combustion. Oxygen sensors analyze the exhaust and send data to your car’s engine control unit (ECU). The ECU then adjusts the air-to-fuel ratio t ... read more
