Code P2119 Chevrolet Description
The P2119 code for Chevrolet vehicles indicates an issue with the Throttle Closed Position Performance. This means that the Engine Control Module (ECM) has detected a discrepancy between the actual position of the throttle plate and the desired position as commanded by the ECM. The throttle position sensor (TPS) is responsible for sending signals to the ECM to adjust the throttle position, which in turn affects the air and fuel mixture being delivered to the engine for combustion. When this system is not functioning properly, it can lead to a variety of performance issues for the vehicle.
