Okay so, it's a Hall effect sensor, 3 wire, it works off a 5v reference. I don't see that code listed in service info, but since it states the sensor is shorted to B+, it sounds like the signal wire is reading higher than 5 volts. I will keep looking through service info, but Ill post a wiring diagram of it, you can back probe the sensor signal wire and see what its reading for voltage while the vehicle is running. Just looking at the aftermarket diagrams right now, the sensor shares a Ground with the Exhaust cam sensor and a 5v reference with a bunch of other sensors. I pulled up the crankcase ventilation operations as well if you need that.
I will double check the OEM diagrams to make sure these are correct, but I would first just see what the voltage level is on the signal wire, even with just the key on engine off. If it's shorted to 12-volts, it should show up at key on.
