Toyota RAV4 / Lexus Front Oxygen Sensor 89467-48160 OEM Oxygen Sensor Replacement Emission Compliant

If the engine check light is on, fuel economy worsens, acceleration is weak, or exhaust has a strong odor, the upstream oxygen sensor may be aging and inaccurate, causing air-fuel ratio imbalance. When functioning properly, this sensor feeds real-time exhaust oxygen concentration data to the ECU to precisely control fuel delivery, ensuring combustion efficiency and emissions compliance. This product is an OEM replacement for Toyota RAV4 and Lexus models; OEM number 89467-48160; fits various 2.0L/2.5L engines. Use a dedicated socket during installation to avoid stripping threads; ensure harness connections are secure and unbent.
