Toyota Camry Front Oxygen Sensor 89467-06150 Air-Fuel Ratio Detection

When your Toyota Camry shows idle instability, abnormally high fuel consumption, or check engine light (codes relating to lean/rich mixture), upstream oxygen sensor aging is the likely cause. It monitors air-fuel ratio in real time and feeds ECU to precisely control injection, ensuring efficient combustion and reduced emissions. OEM numbers: 8946706150 (also compatible with 8946733170, 8946758030); fits Camry 2007-2011 (2.0L/2.4L) and some Lexuses ES models. Installation requires a dedicated socket; avoid forcing torque and clean the exhaust interface beforehand; ensure wiring harness avoids contact with hot components.
