What are the effects of a faulty nitrogen oxygen sensor on a car?
2 Answers
As a crucial component of the electronic fuel injection control system, the nitrogen oxygen sensor plays a vital role in ensuring the normal operation of the engine and effective control of exhaust emissions. Below are the specific impacts of a damaged nitrogen oxygen sensor on a car: 1. Warning lights: It will directly cause multiple engine warning lights to illuminate, and the control unit will store relevant fault records. 2. Shortened lifespan: The inability to accurately feedback emission data means the engine control unit cannot precisely adjust emissions, which over time will shorten the lifespan of the exhaust emission treatment equipment. 3. Combustion control disorder: It can lead to combustion control disorder, resulting in symptoms such as weak acceleration, rough idling, and failure to start.
Recently, my car's NOx sensor malfunctioned, and the experience was terrible. On the highway, the power felt significantly weaker, the throttle response was sluggish when accelerating, and fuel consumption noticeably increased, burning one or two liters more per 100 kilometers than before. That annoying check engine light on the dashboard kept reminding me there was a problem. At the repair shop, the technician said the exhaust emissions were exceeding standards, and leaving it unfixed for a long time could even damage the catalytic converter, making repairs more expensive. Additionally, driving in the city gave off a strange smell, polluting the environment. I recommend fellow car owners check this sensor during regular maintenance to avoid extra costs and frustration like mine. After replacing the sensor, all the issues disappeared, and the car runs smoothly again. Remember, timely repairs are crucial.
