Walker Products Oxygen Sensor , Air-Fuel sensors have been engineered and developed to be an OE Manufacturers replacement for many vehicles worldwide. Every part number is manufactured for the specific application, fitment position on the vehicle, and will provide the relevant diagnostic system feedback as required by the ECU. Bank 1 Sensor 1 oxygen sensor is known as Upstream O2 Sensor, Right/Rear Bank 2 Sensor 1 oxygen sensor is known as Upstream O2 Sensor, Left/Front Bank 1 Sensor 2 oxygen sensor is known as Downstream O2 Sensor, Right/Rear Bank 2 Sensor 2 oxygen sensor is known as Downstream O2 Sensor, Left/Front OE Fit, Form, and Function. Engineered, assembled, and 100% performance tested in the USA Corrosion resistant Easy Installation If the oxygen sensor detects a abnormal higher level of oxygen in your exhaust, it can send a signal to the engine control module (ECM) to adjust the fuel-air mixture so it burns more efficiently Dependable oxygen sensor helps reducing fuel consumption and emissions. Walker Products sensor can meets or exceeds OE specifications. We carry exact-fit sensors with OE connectors for easy installation as well as universal sensors with solder-free connectors. A defective oxygen sensor can cause your catalytic converter to fail prematurely. Replacing an oxygen sensor is significant better than replacing a catalytic converter, which can cost thousands of dollars. Improve the chemical reaction rate of oxygen element. Water-proof and stain-proof. If the optimum combustion is not maintained, the engine can emit harmful amounts of carbon monoxide and excessive levels of hydrocarbons. Produce to bring you an O2 sensor that keeps your engine running at its best, for longer.
