    the heaters for the sensors are controlled by a fuse. you need to check it. it may have been one of the sensors that had a bad heater and you fixed it with replacing the bad one. look for the fuse first. if it is ok, then there is another issue. stop replacing parts till you have someone tell you the problem. it gets expensive replacing parts that are not bad.
