How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then work the likely-causes list in the order shown.
That order is what a shop checks first for this code — wiring and connections before the component they run to, because a connector costs nothing to inspect and is a common answer.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.
Common symptoms
- Misfire cyl 10
- Check engine light
Likely causes
- Shorted injectorMost common
- Connector corrosion
Read the full diagnostic procedureP0288 sets when the cyl 10 injector circuit reads low, indicating short to ground or internally shorted solenoid, and only applies to V10 engines.

Cheapest first
- swap injector 10 with another cylinder;
- PFI windings should ohm 11 to 17, with shorted coils reading 4 to 9 ohms.
- With the connector disconnected and key on, the driver-side pin should be open to ground; continuity to chassis ground indicates harness short.
- Pulse width at warm idle on the Ford 6.8L Triton runs 3 to 4 ms; on the BMW S85 V10 it runs 2 to 3 ms.
- Caveat: the Ford 6.8L V10 cylinder 10 is at the very back of the driver side and harness service requires upper intake removal on most years; do not pull injector connectors with the harness cold-soaked in subfreezing temps, because the connector locking tabs become brittle and snap off, converting a $0 inspection into a $90 pigtail repair.

How do I diagnose a P0288 code?
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed. 1. Note every code that is set, not just this one. 2. Read the freeze frame — the conditions the fault was recorded under. 3. Confirm the fault is current rather than history. 4. Then work the likely-causes list in the order shown.
