Maintaining your Honda's oxygen (O2) sensors is crucial for optimal performance and fuel efficiency. Regularly check for signs of wear, such as rough idling or a decline in fuel economy, which may signal the need for replacement. To extend the lifespan of your sensors, avoid using fuel additives and ensure your engine is running correctly. When selecting a new O2 sensor, choose between narrow-band and wide-band types; the former is standard on most older models, while the latter offers greater precision and is common on newer vehicles. High-quality materials and proper installation are key to ensuring the longevity and reliability of your O2 sensors, which play a vital role in regulating your Honda's air-fuel mixture.
