Oxygen Sensor for Toyota Corolla Front Upstream With Lambda Air Fuel Ratio Monitor Replacement
The Toyota Corolla Front Upstream Oxygen Sensor with Lambda Air Fuel Ratio is a precise, ready-to-install O2 sensor designed to help your engine maintain the optimal air-fuel mix. By monitoring exhaust oxygen levels before the catalytic converter, this upstream sensor provides real-time data to the engine control unit, promoting better fuel efficiency, lower emissions, and smoother engine performance across all driving conditions. Its built-in heating element ensures fast warm‑up, so readings are accurate from the moment you start the engine, even on cold days.
Specially engineered for compatibility with Toyota Corolla 2019–2021 4‑cylinder 2.0L models (M20AFKS, M20AFXS; MZEA12L-AEFSBA, MZEA12L-AEXSBA, MZEA12), and Lexus UX200/UX250h from 2019–2021, this sensor supports multiple OEM references to guarantee a precise fit. OEM part numbers include 89467-12280, 89467-02130, 8946702130, 8946712280, and variations like 89467 12280. With its upstream placement, it delivers reliable readings early in the exhaust stream, helping the vehicle reach ideal combustion conditions quickly and consistently.
