i am not sure on the 1139 or the 381
but the 470 the sensor is mounted on the front of the engine with a tube that runs over to the pass side exhaust manifold and the tube will get plugged and gum up the sensor, you can remove the tube and sensor and clean them out, i had the same problem on my truck about a month ago and just cleaning it helped me. give it a try to remove the tube just need a 17mm wrench.
