Description
Automotive oxygen O2 sensors are critical feedback sensors in electronic fuel injection (EFI) engine control systems. They play a key role in controlling vehicle exhaust emissions, reducing environmental pollution, and improving fuel combustion quality in automotive engines.
By measuring the oxygen ion concentration in the exhaust gases, the sensor provides the air-fuel ratio (A/F) signal to the engine control unit (ECU). When the air-fuel ratio is around 14.7, the engine achieves the optimal mixture concentration, leading to improved fuel efficiency and reduced harmful gas emissions.
Application
These sensors are used to detect the oxygen content in vehicle exhaust gases and convert it into an electrical signal. This allows the control system to adjust fuel injection and ignition timing, ensuring optimal combustion efficiency and fuel economy.
Features
- High accuracy, fast response, high temperature resistance

Technical Support:
Customized technical design and function, LOGO and package are available without extra charge (including molding fee) for mass volume.
The sensors don't have sleeping mode. It can be set in program if needed.
All Winsen products go through strict inspections and tests to make sure they are 100% qualified before shipping out.
The sensor has been fully tested (not calibrated) before leaving the factory, but the module will be calibrated before leaving the factory.
However, after transportation and storage, the environment conditions change, and the surface of the sensor absorbs moisture, mixed gas, pollution matters, etc. It is recommended that customers perform aging and calibration after sensors become stable according to the program and use occasions of the whole device.
15﹪-90﹪RH without condensation,greater or less than this range or long-term high temperature and high humidity will affect the life of the sensor.
Our sensors are certified with CE, 3C, ROHS, anti-explosion, fire prevention, and coal mining safety according to different applications. And we provide assistance for new certification.
Many factors can cause the sensor to fail such as broken wires in transportation, poisoning, falling off of the sensitive material, damage to the heating wire (device), etc. Please find specific cause in each category with Winsen’s aftersales.
Winsen provides professional consultation and service before and after sales. We will recommend the best fitting sensor for your demand. If you have any problem, don’t hesitate to email us to sales@winsensor.com
