Error code P1128 on a 2008 Dodge Ram indicates that the powertrain control module (PCM) has detected a problem with the fuel trim system, specifically related to the air-fuel mixture being too lean. This code often points to issues such as a vacuum leak, malfunctioning fuel injectors, or problems with the mass airflow sensor. It may also suggest that the engine is not receiving enough fuel. Diagnosing the exact cause typically involves checking the fuel system, intake leaks, and related sensors.
