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.
Medium severity. Can I keep driving?If the car is running normally, drive in moderation to a repair shop. If it loses power or another warning appears, do not continue.
Cylinder 2 is numbered according to the manufacturer: check your engine's manual before working on it.
Symptoms
- Check engine light
- Often no running fault; with a worn injector, knocking or rough idle
Most 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
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- Repair difficulty: medium
- It affects emissions.
What each character of P2B13 means
- P: Powertrain: engine and transmission
- 2: Generic code: same on every make
- B: Subsystem depends on the code range
- 13: Specific fault in that system
Frequently asked questions
Can I keep driving with code P2B13?
If the car is running normally, drive in moderation to a repair shop. If it loses power or another warning appears, do not continue.
What causes code P2B13?
The most common causes are: 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.
