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.

P0267 sets when the cylinder 3 injector control circuit reports current below the expected threshold during ECM commanded pulse-width, indicating a short to ground in the injector low-side circuit, a shorted injector winding, or a failed ECM injector driver channel.
Cheapest first
- with key off, unplug the cylinder 3 injector and measure resistance across the injector pins — 11-17 ohms is normal for saturated-driver high-impedance injectors, 1.5-4 ohms for peak-and-hold low-impedance; readings well below the low end confirm a shorted winding.
- Inspect the harness from the connector along its full routing — cylinder 3 sits in a position where the harness frequently crosses fuel rail brackets or EGR plumbing and is prone to chafe-through to ground.
- Confirm the 12 V supply on the injector feed side (should be battery voltage with key on if non-cycled, or pulsed if injector relay is cycled) and verify the ECM is still driving the low side with a noid light.
- Caveat: a recent timing chain or head gasket service that disturbed the injector harness is a common precursor to P0267 — inspect for pinch points under intake manifold reinstallation before assuming a sensor or injector fault.

Typical symptoms: Misfire cyl 3; Check engine light.
Is it safe to drive with a P0267 code?

How do I diagnose a P0267 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.
