氧传感器 89465-52040

Oxygen sensor on exhaust pipe for Toyota Camry and other models, OEM 89465-52040 (also compatible with 89465-06250, 06230, 06240 and 33440). It monitors exhaust oxygen content in real time and feeds signals to the ECU to precisely adjust the air-fuel ratio, ensuring combustion efficiency and emission compliance. If the check engine light is on, fuel economy is poor, idle is unstable, or acceleration is weak, the sensor may be failed. Installation difficulty is moderate; about 0.5–1 hour; take care to avoid thread damage.
