Toyota Oxygen Sensor 89465-42100/33160/28290, Multi-Model Universal Replacement Part

When your Toyota vehicle shows rough idle, noticeably higher fuel consumption, check engine light on, or annual inspection emissions exceeding standards, it usually indicates the oxygen sensor aging and failure, unable to accurately monitor exhaust oxygen content. The sensor, when functioning correctly, sends an air-fuel ratio signal to the ECU to maintain optimal combustion, reduce emissions, and boost power response. This replacement fits many Toyota models; OEM number 89465-42100, also compatible with 33160 and 28290 models. Before ordering, check vehicle connector and harness length. Use a dedicated socket during installation to avoid cross-thread damage, and keep the sensor wiring away from high-temperature exhaust areas to prevent short circuits.
