Here's what you should know:
- The oxygen sensor is responsible for measuring the amount of oxygen in the exhaust gases.
- This information is then used by the engine control unit (ECU) to adjust the air-fuel mixture.
- A faulty oxygen sensor can cause the ECU to receive incorrect information, resulting in an incorrect air-fuel mixture.
Too much or too little fuel in the air-fuel mixture can lead to decreased gas mileage.
Additionally, a faulty oxygen sensor can cause the engine to run poorly, which can also lead to decreased gas mileage.
Therefore, it is important to replace an old or faulty oxygen sensor as soon as possible to ensure optimal gas mileage and engine performance.
