Improve engine efficiency performance If the oxygen sensor detects a higher level of oxygen than is normal in your exhaust, it can send a signal to the engine control module (ECM) to adjust the fuel-air mixture so it burns more efficiently |
Increases fuel economy The oxygen sensor helps reduce fuel consumption and emissions. AutoZone stocks dependable oxygen sensors so you can drive comfortably knowing that your sensor meets or exceeds OE specifications. We carry exact-fit sensors with OE connectors for easy installation as well as universal sensors with solder-free connectors. |
Reduce CO2 and other harmful emissions In your car, a functioning O2 sensor ensures that your engine is running at top performance. Replacing a defective O2 sensor helps ensure your engine is constantly monitored and operating efficiently, while maximizing performance |
Extend expensive Catalytic Converter life A defective oxygen sensor can cause your catalytic converter to fail prematurely. Replacing a catalytic converter can cost thousands of dollars, significantly more than most standard oxygen sensor replacements |
