Defouler 02 sensor

The role of the oxygen sensor is to effectively control fuel emissions for better engine performance and fuel economy. It analyzes the exhaust fumes and deposits produced by the engine to gather data of the air-fuel ratio. If the ratio is off, the sensor sends feedback to the vehicle's engine control system so the fuel mixture can be adjusted ...

02 sensors measure the amount of oxygen in the exhaust and report the level to your vehicle's computer. There are O2 sensors before and after the catalytic converter. The upstream O2 sensor controls how much fuel is added to the air/fuel mixture. The downstream O2 sensor makes sure the catalytic converter is working.8 Oxygen Sensors found. View related parts.
