Oxygen Sensor for Toyota Sequoia 2008-2012 4.6L 4.7L 5.7L

Upgrade your Toyota Sequoia with a reliable upstream oxygen sensor replacement designed for 2008–2012 Sequoia models featuring 4.6L, 4.7L, or 5.7L engines. This heated, piezoelectric sensor delivers fast, accurate oxygen readings to the engine control unit (ECU), helping you maintain the correct air–fuel mixture for cleaner emissions, better fuel economy, and smoother performance. The direct-fit design matches OEM mounting and electrical connectors, making installation quick and straightforward without any modifications. With a heated element, it warms up quickly for precise readings during cold starts, improving drivability in all weather conditions.

Replacing a worn upstream oxygen sensor can solve common issues like rough idle, reduced mileage, and a stubborn check engine light. This sensor restores proper feedback to the ECU, supports efficient catalyst operation, and helps your Sequoia run efficiently again on every trip—from daily commutes to long highway journeys.

In addition to Sequoia compatibility, the sensor is suitable for a range of Toyota/Lexus applications listed in the product data, ensuring you’re getting a trusted, high-quality component designed to fit multiple upstream positions across related models.

Benefits & Tips

• Heated upstream sensor for quicker catalyst warm-up and more accurate readings, especially in cold climates.
• Piezoelectric sensing provides precise oxygen measurements to optimize fuel trim and reduce emissions.
• Direct-fit replacement with OEM-style connectors helps ensure an easy install and reliable long-term operation; verify the orientation (Right or Left) for your specific model.
