How to Reset the ECU After Changing an O2 Sensor | It ...

It determines the amount of oxygen in the gases, which indicates how well the fuel is being burned. The O2 sensor then sends information to the electronic control unit, or ECU, the vehicle's computer. The ECU then adjusts the air-to-fuel ratio to optimize the fuel combustion. Sometimes an O2 sensor fails, and you need to replace it. Once you've replaced your vehicle's O2 sensor, you'll need to reset the ECU so it can properly gather information from the new O2 sensor.
