凯美瑞 氧传感器 89467-33160 原厂标准替换 提升燃油效率

Toyota Camry (2007-2017, many 2.0L/2.4L/2.5L) front oxygen sensor, OEM 89467-33160; installed in front of the exhaust. Monitors oxygen content and feeds ECU to achieve precise air-fuel ratio; improves fuel economy and reduces emissions. If check engine light on, fuel consumption surges, idle unstable, or acceleration slow to respond, sensor signal is out of spec. Replace using dedicated tools to avoid thread damage; labor about 0.5-1 hour.
