Toyota Highlander Oxygen Sensor 89465-0E070 Multi-Model Compatible (0E070/48250/48110)

When your Toyota Highlander exhibits idle instability, higher fuel consumption, weak acceleration, or an illuminated check engine light, it's usually due to aging or failing oxygen sensors unable to accurately monitor exhaust oxygen. The sensor provides real-time A/F feedback to ECU to maintain optimal combustion and lower emissions. This replacement fits Toyota Highlander models with OEM numbers including 89465-0E070, 89465-48250, 89465-48110; verify compatibility before ordering. Use a dedicated oxygen sensor socket, avoid damaging threads, and apply anti-seize compound to the threads for future removal. Cold-start operation recommended.
