The DENSO Oxygen Sensor, also known as an O2 sensor, showcases superior engineering for optimal performance. Symptoms of a faulty or bad oxygen sensor include bad gas mileage, rough idle, reduced drivability, and an illuminated check-engine light.
Installed on 2005 Dodge Ram 1500. Product looked exactly like the original equipment part including the pigtail connector. Only used it for 6 months now and, so far, everything works fine.
