just because a code says that this part is faulty, does not mean that the sensor itself it bad. it means that the sensor is either faulty or is registering something outside the normal parameters. this might be a wire that was broken feeding the sensor. in this case, it might be better to scan it, not code read, to find out exactly where to start.
