Thanks for asking your question. I will try and help you out.
Your troubleshooting is correct. When jumping changes the code to a -4 short. The sensor should have been the problem.
Since the -3 came back, you either got a bad out of the box sensor, which is rare.
Or there is an intermittent problem in the wiring harness.
Please reply back if you need more help or have more questions. I am happy to assist.
