Automotive Oxygen Sensor

Sustain and optimize your fuel economy

Automobile o2 sensor is also known as "O2 Sensor" and "Lambda Sensor", is a critical component in the fuel injection system. It helps the system measuring the oxygen contents in exhaust gas then output signals in voltages to ECU (Electronic Control Unit) to calculate the air-fuel mixture of exhaust gas. Vehicle must maintain an air and fuel mixture of 14.7:1, the industry's standard for efficient and optimal emission. Too much oxygen in this ratio means the engine is running lean, resulting in poor engine performance. Too much fuel in this ratio means the engine is running rich, result in bad fuel economy and high emission. Both conditions may shorten the lifespan of a vehicle's engine and catalytic converter.


Ceradex, professional car sensor manufacturers, has patented automobile O2 sensor technology which enables our sensors to achieve and exceed OEM o2 sensor's specification and performance. With self-developed and produce sensors' core ceramic element, Ceradex has the widest range available for both OEM and aftermarket replacement sector.
