Oxygen Sensor Gasket

About this product

The Oxygen Sensor Gasket (#89466-20020-83), an essential auto part in Toyota's Electrical Switch & Relay & Computer and Engine-Fuel Manifold systems, plays a significant role in sealing the connection between the oxygen sensor and the exhaust pipe. During operation, the gasket ensures that exhaust gases do not leak out, maintaining proper pressure and flow, crucial for the oxygen sensor's accurate readings. As the gasket ages, it can become clogged or broken, potentially causing misreadings, incorrect fuel/air mixtures, and increased emissions. Therefore, periodic replacement is critical to maintain optimal vehicle performance. Genuine Toyota parts, such as this gasket, are compatible with your vehicle and are backed by Toyota's genuine parts warranty. By maintaining leak-free conditions and accurate oxygen sensor readings, this gasket is instrumental in keeping the engine running efficiently and safely.
