P0267 Cylinder 3 injector A circuit low
What P0267 means
The engine computer sees a voltage that is too low in the control circuit of the cylinder 3 fuel injector. Usually the control wire is shorted to ground or the injector coil is shorted. Depending on the fault, the injector may stay shut, causing a misfire, or stay open and flood cylinder 3 with fuel.
P0267 is a generic SAE J2012 code: it means the same on every make. The exact cause still depends on the car, so read the freeze-frame data before replacing parts.

Symptoms
- Check engine light on
- Misfire on cylinder 3
- Rough idle and reduced power
- Possible fuel smell or black smoke
Common causes
- Injector control wire shorted to ground (chafed harness)
- Internally shorted cylinder 3 injector coil
- Corroded or damaged injector connector
- Engine control unit injector driver fault (rare)
Can I keep driving with P0267?
You can drive gently, but have it checked within one to two weeks. If cylinder 3 misfires, the engine smells of fuel or the check engine light flashes, stop driving: excess fuel can dilute the oil and damage the catalytic converter.
What to check first
- Inspect the cylinder 3 injector connector and harness for chafing against metal edges.
- Measure the cylinder 3 injector coil resistance and compare it with the other injectors.
- With the injector unplugged, check the control wire for a short to ground.
- Replace the injector or repair the wiring, depending on what the tests show.
