Codes P2BEC and P2BEE on 2019 Ford Mustang GT ESS Supercharger, VMP BAP and Lu47's on pump 93 and Octane Booster

[TEXAS HEAT]

Has anyone experienced codes P2BEC which is (fuel control system A too lean bank 1) or P2BEE which is (fuel system A too lean bank 2) if so what was the root issue?

This occurs at even part throttle very slow driving and triggers a CEL. I've cleared it once and it came back very shortly thereafter.

VMP BAP and Lu47's on the ESS Supercharger. Pump 93 and octane booster for unleaded applications.

Any help or advice is appreciated.

Two years later, wondering if you ever found out the issue. I’m having these codes pop up and my tuner has sent me numerous modifications of my tune which adds fuel and it keeps coming back. It’s not the normal lean code (P0171) and can’t find anything for this.

How do your short term fuel trims look?

The code issue that I was having when I posted this eventually either self-remedied or the multiple tune revisions since then potentially cleared it, but I do not know for sure what was done, if anything by the tuner to get them to go away. They have not returned since in over a year and a half, so idk...
