P2BEFFuel Control System A Too Rich Bank 2
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2BEF says that the engine module has had to take away a lot of fuel on bank 2 while direct injection alone was supplying the cylinders. Ford sets it on port-plus-direct engines when long-term trim on that bank drops past minus 25 percent while short-term trim keeps subtracting more than 1 percent; two seconds in closed loop are enough. Because the common rich fault P0175 is reserved for enrichment seen in every mode, P2BEF points at the DI hardware of bank 2: a direct injector that sticks open or seeps after shutdown, or a rail pressure reading that is too low so the pump overshoots. On 2019 and 2020 F-150 2.7 L EcoBoost trucks built until 4 July 2020, Ford bulletins 20-2257 and 21-2045 cure this code, together with the other fuel-trim codes, by reprogramming the PCM.
