Hi there. The scan might indicate that your primary O2 sensor is damaged, or the electrical harness that connects to the sensor is damaged. This would cause the symptoms you’re describing in most cases. I would recommend having a professional mechanic complete a car is getting worse gas mileage inspection to verify that other problems are not causing this issue.
