Downstream Oxygen Sensor for Toyota Sienna 2011-2015 3.5L V6
Discover reliable performance with the Downstream Oxygen Sensor designed for the Toyota Sienna 2011–2015 3.5L V6. This downstream sensor, mounted after the catalytic converter, plays a crucial role in maintaining optimal exhaust gas readings. By providing accurate feedback to the engine control system, it helps fine-tune the air-fuel mix, support efficient fuel usage, and reduce emissions—keeping your Sienna running cleanly and efficiently.
Built as a heating-type, piezoelectric sensor, it warms quickly to deliver stable, precise signals even in cold starts. This means faster sensor response, smoother idle, and improved catalytic converter efficiency. With compatibility for the 2011–2015 Toyota Sienna 3.5L V6, it’s a drop-in upgrade that supports longevity and reliable performance over time.
Your purchase covers the essential compatibility with OEM equivalents from the Toyota ecosystem, including part numbers such as 89465-08060, 89465-08110, and 234-4540 (among others listed in the product data).
