The malfunction of an oxygen sensor, a critical component in a vehicle’s emissions control system, stems from various factors that degrade its functionality over time. These factors typically involve contamination, physical damage, or electrical failure. Understanding the root causes of sensor degradation is essential for proper diagnosis and maintenance.
Proper functioning of the sensor is crucial for optimizing engine performance, reducing harmful emissions, and ensuring fuel efficiency. A malfunctioning sensor can lead to increased fuel consumption, poor engine response, and potentially damage to other engine components. Early detection and replacement can prevent more significant and costly repairs. Historically, the development of oxygen sensors has been integral to meeting increasingly stringent emissions regulations globally.
