Q: What does code P2697 mean?

Exhaust Aftertreatment Fuel Injector A Circuit / Open. P2697 indicates that the powertrain control module (PCM) has detected an open circuit or excessive resistance in the electrical path for the exhaust aftertreatment fuel injector designated as 'A'. This injector is responsible for delivering diesel fuel or a similar reductant into the exhaust stream to raise temperature for components like the diesel particulate filter (DPF) or to support regeneration, and an open circuit prevents that delivery from occurring.
