Product Details

Oxygen Sensor (21546) by NTK®. Position: Upstream Passenger Side. Location: B2S1. Thimble type sensors feature a ceramic element that projects into the exhaust system and becomes electrically conductive at high temperature. The sensor element then sends voltage signals back to the engine management system to regulate the air to fuel ratio, for optimum efficiency. All oxygen sensors are platinum coated for durability and are individually tested to guarantee quality.

Today, everyone agrees that we have to care about our environment and reduce the amount of pollution produced by vehicles. To encourage reduced emissions, the government has introduced tougher exhaust gas emission legislation. As a result, today modern vehicles are equipped with oxygen sensors that control the fuel and ignition systems to optimize vehicle performance in the areas of fuel economy and emissions. Generally, a vehicle is equipped with two oxygen sensors located before and after the catalytic converter. They check the amount of oxygen in the exhaust and send signals to the vehicle's on-board computer that regulates the air/fuel mixture and monitors catalytic converter function to ensure proper engine performance, optimum mileage, and low emission of air pollutants from the vehicle.

If it happens that your oxygen sensor is failed or worn out, you will experience increased fuel consumption and poor driveability. Moreover, the catalytic converter might be failed. In addition, your four-wheel friend will fail emission test. So, if testing shows your sensor is fault, don't hold on and replace it with this first-class oxygen sensor by NTK designed and manufactured to meet OE requirements for fit, form, and function. The sensor is made of first-grade materials and equipped with waterproof factory fitted connectors to ensure long-lasting durability and perfect fit. It's built with sensing element incorporating exclusive NTK's premier technical ceramics. To guarantee reliability and premium quality, the product is extensively tested during manufacture process.
