NGK Toyota Sienna 2010-2004 Direct Fit Oxygen Sensor

This NGK oxygen sensor is designed to be a direct fit for your 2004-2016 Toyota Sienna. Oxygen sensors are a key part of your vehicle's onboard diagnostic system. They constantly send information to the engine control unit (ECU) about the air-fuel ratio, which is crucial for keeping the engine running smoothly, getting the best possible gas mileage, and reducing exhaust emissions.

NGK, a major supplier of original equipment oxygen sensors, uses advanced ceramic technology in their sensor elements. This particular sensor features a 3-stage contaminant-resistant plasma jet and deposit trap overcoat. This design helps protect the sensor element from poisoning, which can happen over time from exhaust contaminants. By providing accurate feedback to the ECU, this sensor helps ensure your engine is running efficiently and can also alert you to potential issues with fuel delivery or the catalytic converter.
