丰田氧传感器 89467-0E030/89465-0G080/89465-52430 尾气达标替换件

When your Toyota shows idle instability, weak acceleration, higher fuel consumption, and the check engine light (P0135/P0141 or other oxygen sensor codes) is on, the original oxygen sensor has aged out and cannot accurately monitor oxygen content in exhaust. When working properly, the sensor provides real-time A/F feedback to ECU to ensure the catalytic converter efficiently converts harmful gases for compliant emissions. This replacement is compatible with OEM numbers 89467-0E030, 89465-0G080, 89465-52430, for various Toyota models (e.g., Camry, RAV4, Corolla). Installation should be done cold; use an oxygen sensor socket to avoid thread damage, and apply anti-seize compound for high-temperature resistance.
