Mufflers are susceptible to rust and corrosion, especially in regions with harsh weather conditions and road salt. If you notice visible rust or corrosion on the exterior of the muffler, it may indicate wear and potential weaknesses in the metal. Over time, mufflers can also develop perforations due to corrosion or physical damage. If you see exhaust gases coming from the muffler, it is a clear sign of a leak. If you suspect muffler issues based on these signs, it is advisable to take your vehicle to a muffler shop for assessment and repairs.
Oxygen Sensor Malfunction
Oxygen sensors monitor the levels of oxygen in the exhaust gases and provide feedback to the engine control unit for adjusting the air-fuel mixture. An illuminated check engine light on the dashboard is one of the most common signs of oxygen sensor malfunction. The engine control unit detects unusual readings from the oxygen sensor and triggers the check engine light to alert the driver. A malfunctioning oxygen sensor can disrupt the proper air-fuel mixture in the engine, leading to decreased fuel efficiency. If you notice a sudden drop in gas mileage or have to refuel more frequently than usual, it may indicate an issue with the oxygen sensor. A malfunctioning oxygen sensor can contribute to higher emissions levels, including increased production of pollutants such as carbon monoxide and nitrogen oxide. This can lead to a failed emissions test.
If you notice any of these signs and issues, it is advisable to consult a qualified mechanic. Properly maintaining your car’s exhaust system at your local auto repair shop can help you prevent significant issues, extend the life of exhaust system components, and contribute to a cleaner and safe driving experience.
