Universal Oxygen Sensor 89465-42090 for Toyota Multi-Model Replacement, Compatible with 89465-42100/33160

This oxygen sensor directly replaces factory number 89465-42090 and is also compatible with 89465-42100 and 33160, a universal design with no installation issues. It monitors oxygen content in exhaust and sends signals to the ECU to adjust air-fuel ratio, ensuring efficient engine combustion. Fits multiple Toyota models such as Camry, Corolla, and RAV4; check the original vehicle interface for specific year. Replacing resolves high fuel consumption, weak acceleration, and engine-check-light issues, and helps emissions meet standards. If your vehicle idles unevenly, exhaust emits black smoke, or fuel consumption spikes, this sensor is aging and should be replaced promptly.
