Solving the error will probably become a process of elimination and deduction. Check both ends of the sensor cable connectors for oil, dirt and grime. Then wiggle the cable around and see if a voltage signal results. Some have found sensor cables with broken wires inside them - especially in areas of high heat. Example O2 sensors. Consider replacing the sensor cable just to be certain. So #1 = New sensor. #2 = Clean sensor cable connections and check connectors. #3 = Check sensor cable continuity of voltage conduction when removed from the car. #4 = get a new Sensor Cable? This is all I can think of for the moment. It's also possible the new sensor could still be a bad one. Good luck.
