P0267 indicates that the engine control module (PCM) has detected an electrical value in the cylinder 3 fuel injector circuit that is lower than expected. This usually means the control circuit is seeing excessive resistance, an open circuit, or a short-to-ground condition on the cylinder 3 injector wiring or injector coil.
The injector coil may be open, shorted, or have high resistance, causing the PCM to see a low-current or low-voltage condition on the driver circuit.
Corroded, loose, bent, or damaged pins and harness breaks between the injector and PCM can raise resistance or create an open circuit.
Chafed or pinched insulation on the injector driver wire can short to the engine block or another ground, pulling the circuit voltage low.
The output transistor that switches the cylinder 3 injector can fail, but this is uncommon and should only be considered after the injector and wiring are proven good.
It is best to avoid extended driving. A dead or weak injector can cause a persistent misfire, which may overheat and damage the catalytic converter.
No. Wiring and connector problems are very common causes. The injector itself should be tested and the circuit verified before any parts are replaced.
No. PCM injector driver failure is rare for this code. Most fixes involve the injector or the wiring between the injector and PCM; the PCM should be suspected only after everything else is ruled out.
No. P0267 is an electrical circuit fault code. A clogged injector would more likely cause a performance or misfire issue without setting this specific circuit-low code.
