  1. Product Introduction

Premium Wideband A/F Oxygen (O2) Sensors is the major sensor component in electronic fuel injection engine control system, and is the key part to control automotive exhaust emission, reduce automotive pollution and improve fuel combustion quality. Oxygen sensor is used in the feedback control system of the electronic control fuel injection device, to detect the concentration of oxygen in the exhaust gas and the air fuel ratio. It is also used to monitor theoretical air fuel ratio (14.7:1) combustion in the engine, and to provide feedback signals to the computer.

  1. Product Features

Wideband/Air-Fuel sensors perform the same function as a regular O2 sensor, but they precisely measure the amount oxygen in the exhaust rather than just switching between rich (too much fuel, not enough oxygen) and lean (too much oxygen, not enough fuel). Our Wideband sensors use a more sophisticated sensing element that provides a signal to the vehicle’s ECU that is proportional to the amount of oxygen in the exhaust. They have the following key features:

  • Advanced Wideband sensing element for exact air/fuel measurement
  • Robust sensor design increases sensor longevity
  • Seared protection tube due to 100% functional quality test
  • Pre-coated threads with anti-seize compound right out of the box
