Whether you’re driving through San Angelo traffic on Sherwood Way or heading toward Lake Nasworthy, a healthy oxygen sensor keeps your car reliable and fuel-efficient.

What the Oxygen Sensor Is and How It Works
The oxygen sensor is a small electronic device located in your exhaust system. Since it measures the amount of oxygen in exhaust gases, it sends data to the engine control unit (ECU). Then, the ECU adjusts the air-to-fuel ratio to ensure proper combustion. Because the sensor works every time your engine runs, it plays a constant role in performance, efficiency, and emissions.
So, Why the Oxygen Sensor Is Important
Although it may be small, the oxygen sensor has a major impact on your vehicle’s health.
-
Since it improves fuel efficiency, it saves you money at the pump.
-
Because it ensures proper combustion, it reduces harmful emissions.
-
Since it prevents rough idling and misfires, it keeps your engine smooth.
-
Because it protects the catalytic converter, it helps you avoid costly repairs.
