Welcome to AF!!

Did you use teflon tape on the threads? If so remove the sending unit and remove the teflon tape. Use a conductive thread sealant and the problem should go away. The unit relies on the threads for ground and if the teflon tape interferes with that the unit may not work properly and set a code.
