What are the symptoms of a broken Oxygen Sensor in a car?

Oxygen sensors are one of the key elements in an vehicle's emissions system and, if faulty, can negatively impact a car's fuel economy and performance. Here are some common symptoms that can be caused by a malfunctioning oxygen sensor:

Decreased engine power: Failure of the oxygen sensor can lead to insufficient fuel supply or over-concentrated mixture, which can affect the power and acceleration performance of the engine.

Increased fuel consumption: If the oxygen sensor fails, the ECU may adjust the supply of the mixture, resulting in reduced fuel economy and increased fuel consumption.

Engine idle instability: Oxygen sensor failure can cause the mixture to be too concentrated or too lean, resulting in engine idle instability.

Difficulty starting the engine: A malfunctioning oxygen sensor can cause the mixture to be too concentrated or too diluted, resulting in difficult or impossible engine starting.

Excessive emissions: If the oxygen sensor fails, the ECU cannot properly adjust the supply of the mixture, resulting in excessive emissions and thus failing the emission test.

If your car exhibits any of the above symptoms, it is recommended to check whether the oxygen sensor is working properly in time. If the oxygen sensor needs to be replaced, it is recommended to choose original parts or high-quality replacement parts that match the vehicle, and ask a professional technician to install and debug.
