Maintaining the O2 sensors in your Dodge is crucial for optimal performance and fuel efficiency. Regularly check for signs of wear such as rough idling or a sudden drop in mileage, which may indicate the need for a replacement. To extend sensor life, avoid using leaded fuels and ensure your engine is running correctly to prevent contamination. When shopping for new O2 sensors, choose between narrow-band and wide-band sensors; the former being standard for most models, while the latter provides more precise readings for high-performance vehicles. Always opt for sensors with high-quality materials to withstand harsh engine conditions, and for DIY enthusiasts, remember to apply anti-seize compound on the threads during installation to facilitate future removal.
