P2B13 concerns injector 2 on Ford's Power Stroke diesels: its zero-fuel learn value has run past the permitted band. Ford's 2023 OBD summary shows when the learn runs: continuously, typically within about 30 s, with coolant of at least 50 °C, intake air between 0 and 75 °C, fuel of at least 10 °C, at least 10 V supply, almost no pedal (up to 2 %) and rail pressure within 50 bar of its target. A real deviation is not the only trigger, though. Special service message 48877 for 2017–2019 F-Super Duty 6.7 L trucks explains that abnormal steering wheel oscillation can put noise on the crank or cam sensor frequency and set these codes; if they stay away after clearing, no injector work is to be done. Balance code P0266 often appears alongside.

Likely causes

Steering wheel oscillation disturbing the crank or cam signal (Ford SSM 48877)

Injector 2 with genuinely shifted opening time due to wear or deposits

Implausible learned values in the PCM

Symptoms

Check engine light
Often no running fault; with a worn injector, knocking or rough idle
