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.

Cheapest first
- swap injector 10 with a neighbor and clear codes; a migrating code confirms an open winding.
- Ohm test: PFI 11 to 17 ohms expected (Ford 6.8L, Viper 8.3L), BMW S85 GDI-style runs 1.5 to 4 ohms;
- OL confirms broken winding.
- Key-on engine-off, feed pin should read battery voltage, driver pin should rise to within 1V of battery through the coil.
- With scope on driver line during crank, expect clean square pulldown under 1.0V at each pulse command; missing pulse means open between PCM and injector or failed driver.
- Caveat: on the Ford 6.8L Triton, the cylinder 10 plug well is famous for blowouts (the 2V threads are notoriously shallow), so always inspect for spark-plug ejection damage before condemning injector or harness; a blown plug can both damage the harness and depressurize that cylinder enough to confuse misfire diagnostics.

- 1999to 2010 Ford 6.8L V10 Triton dominates this code, with cylinder 10 spark plug blowouts (2V engines) and rear-bank harness chafe being the top two causes;
- 2006to 2010 BMW M5/M6 S85 has documented injector winding failures past 60k miles;
- 2003to 2010 Dodge Viper 8.3L V10 SRT-10 has heat-cracked injector connectors at the rear cylinders.

How do I diagnose a P0289 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.
