丰田普拉多氧传感器 89465-0G020 前氧传感 原厂标准

Toyota 4x4 Prado front oxygen sensor (OEM 89465-0G020) directly replaces OEM part; versatile across Prado series. Monitors oxygen content in exhaust and sends signal to ECU to adjust air-fuel ratio, ensuring combustion efficiency. After installation, issues like high fuel consumption, weak acceleration, or engine light may be resolved. If idle is unstable, exhaust smell is strong, or fuel consumption rises, front O2 sensor aging is likely; replace promptly to avoid impairing engine performance.
