How to Clean a Chevy Silverado Oxygen Sensor – The oxygen sensor, or O2 sensor, in your Chevy Silverado collects information about your truck’s emissions output and sends this information to the truck’s electronic control unit, or ECU. The ECU then adjusts the air to fuel ratio to make sure that the emissions are reduced to a minimal amount, that fuel economy is optimized, and the power output is optimized for the amount of fuel being used in the engine.
