I think that since like you said injectors on each bank share the ground an internal short in one of the injector could short the entire bank, no?

Can't say for sure because if you look at the attached SIB,it actually states single injector fault codes.Its weird Now I remember bluedragon had same 4B99 code and in the end ,he had to replace all 3 (bank 2) injectors.
