NGK Toyota Sienna 2014-2011 Direct Fit Oxygen Sensor

When you're working on your 2011-2014 Toyota Sienna and need to replace an oxygen sensor, this direct-fit unit from NGK is what you'll get in the box. Oxygen sensors are a key part of your vehicle's onboard diagnostic system. They constantly send information back to the engine control unit (ECU) to help keep the air-fuel mixture just right, which is important for getting the best gas mileage and keeping emissions in check. If the sensor isn't working correctly, your OBDII system can alert you to potential issues with fuel delivery or the catalytic converter.

NGK, a major supplier of original equipment sensors, builds these with an advanced ceramic element. This element has a special plasma jet and deposit trap that helps protect it from contaminants that can cause it to fail. They work closely with manufacturers from the start of development to ensure the sensor performs well and resists common failure points, so you can trust it to do its job.
