Some 2022-2023 Corvette, Silverado, Tahoe, Suburban, Sierra, Yukon and Escalade models equipped with the 5.3L V8 engine (RPO L84) or 6.2L V8 engine (RPO L87, LT2) may have an illuminated Check Engine MIL along with a number of fuel injector performance DTCs set, including: P30D4, P2B95, P02EE, P02EF, P02F0, P02F1, P02F2, P02F3, P02F4, P02F5, P2B08, P2B09, P2B0A, P2B0B, P2B0C, P2B0D, P2B0E or P2B0F.
These conditions may be caused by a faulty fuel injector. Follow the diagnostic chart for the applicable DTC in the appropriate Service Information too address the issue. If it’s determined that a faulty injector is causing the issue, replace the injector for the appropriate cylinder and reevaluate vehicle operation. (Fig. 3)

TIP: When installing new injectors, be sure that they are clean and free of debris prior to installation. Do not lubricate the injector seals. Always use the new fuel injector collars supplied with the new injector.
Do not replace the Engine Control Module (ECM) if these DTCs are set. GM Engineering is reviewing this condition and additional information will be released when available.
For additional information, refer to #PIP5891.

I have had two 22/23 Escalades with P0205. Both have been open. Weird how both have been on cylinder #5.
I also had a P0205 on a 2023 Yukon. Watch the part numbers on the new injectors. They come double boxed and the inner white box with no labeling was wrong for me. Had fuel trim imbalance codes after replacing for the P0205. Gave me an L87 injector for an L84. Part number on the outer box was correct.
I had 2 2023 GMC yukon come in at the same time. One had a P0205.The other a code p206. Both were injector problem. one shorted. the other open.The p0205 code is not on your list
