Kindly reminder: Finding Your Oxygen Sensor's OEM Part Number Please try to confirm the exact sensor (such as part number, sensor position) for your own car before placing the order. If for any reason you cannot find your oxygen sensor by entering your vehicle's year, make and model, you can find it by its Original Equipment Manufacturer (OEM) number. The OEM part number can be found directly on the part itself. You can also call a dealership with your VIN, and they will provide you with the OEM part number.
