OBD-II trouble code P1174 indicates a problem with the fuel system, specifically related to the fuel trim in the engine. It often suggests that the engine control module (ECM) has detected a lean condition, meaning there isn't enough fuel being injected into the engine compared to the amount of air. This can be caused by issues such as a vacuum leak, faulty fuel injectors, or a malfunctioning mass air flow sensor. It's important to diagnose the underlying cause to prevent potential engine performance issues.
