丰田氧传感器 8945602140 替换89465-52370/52380 省油减排

When your Toyota shows rough idle, weak acceleration, noticeably higher fuel consumption, or the check engine light with oxygen sensor-related codes (P0135/P0141), the original oxygen sensor is aging/failing and cannot accurately monitor exhaust oxygen. Function is to feed real-time air-fuel ratio data to the ECU to precisely control fueling, ensuring combustion efficiency, reduced emissions, and fuel savings. This product is KLP brand oxygen sensor, OEM number 8945602140, interchangeable with 89465-52370/52380, compatible with many Toyota models (e.g., Camry, Corolla, RAV4). Install only with cold engine; use a dedicated socket to remove the old part; apply a small amount of anti-seize to threads and tighten to standard torque to prevent leaks and false positives.
