★ Top Answer
The 2011 Ford Fiesta is equipped with two O2 sensors - one positioned before the catalytic converter and the other after. These sensors help monitor the exhaust emissions to ensure the right air-to-fuel ratio. If there's an issue with the O2 sensors in your vehicle, you might experience rough engine performance and possible issues with fuel mixture. A check engine light on the dashboard will often indicate a problem, and scanning the ECU can pinpoint which sensor is faulty.
