Details of the Lincoln p219b OBD Code

The Lincoln P219B code indicates a fuel trim imbalance in bank 2.

OBD code P219B for Lincoln vehicles indicates a stuck open fuel trim control valve bank 2. This code is triggered by the engine control module (ECM) when it detects that the fuel trim control valve in bank 2 is not functioning properly.

The fuel trim control valve is part of the evaporative emissions system and is responsible for controlling the flow of fuel vapors from the fuel tank to the engine intake.

When the valve is stuck open, it can lead to an imbalance in the airfuel mixture, affecting engine performance and emissions.
