P2BEE Fuel Control System A Too Lean Bank 2

Check engine lightOn
EmissionsRelevant
Drive cycleRequired
Limp modeNo

Here the lean correction concerns bank 2, the cylinder row without cylinder 1, and again only the direct-injection operating mode (fuel system A in Ford terms). Ford applies the same monitor as on bank 1: closed loop, warm engine, purge off, long-term trim above plus 25 percent combined with short-term trim above plus 1 percent for 2 seconds. Comparing banks narrows the search. If only P2BEE is stored, look at components that serve bank 2 alone, such as its direct injectors or its upstream oxygen sensor; if P2BEC appears as well, a shared item like the high-pressure pump or rail pressure sensor is more likely. Ford lists P2BEE in bulletins 20-2324 (2018 F-150 2.7 L) and 22-2393 (2019 to 2021 F-150 5.0 L, reflash and keep-alive memory reset).

Likely causes

Direct injectors on bank 2 restricted
PCM software requiring a Ford update
Bank 2 upstream oxygen sensor reading skewed
Low rail pressure, usually with P2BEC on bank 1 too

Symptoms

  • Check engine light on
  • Slight hesitation under load
  • Often no other complaint
