Is the outside temperature display on your Nissan or Infiniti's dashboard acting up, showing crazy numbers, or just not working? This little sensor is probably the culprit. It's the ambient air temperature sensor (part numbers 27722-3VA0A or 27722-AL500) that mounts outside the car, usually behind the front bumper or grille. It tells your climate control and dash display how cold or hot it is outside. This is a direct replacement that fits a ton of models like the Nissan Altima, Maxima, Murano, Pathfinder, 350Z, GT-R, and Infiniti models like the Q50, QX60, FX35, and many more from the early 2000s to 2020 (check your specific year!). Installation is usually straightforward—locate the old one, unplug it, and plug this new one in. It's made from durable materials to handle weather. A simple fix to get your car's temperature reading accurate again.
