Richpin's Auto Repair takes you through the steps of replacing the front oxygen sensor on a Saturn s-series vehicle. To begin replacing this sensor, you are shown how to remove the resonator box. Once the resonator box is removed you'll be shown a quick tip on how to make the removal of the oxygen sensor a little easier using PB Blaster spray. Next you'll be shown how to remove the electrical connector to the sensor and be given a suggestion on which tools are necessary to remove the sensor from the vehicle. Once removed, installing the new sensor is the reverse process of removal.
