Code P2119 2015 Chevrolet Silverado Description

The Engine Control Module (ECM) determines the driver's intent based on input from the accelerator pedal position sensors, then calculates the appropriate throttle response based on the throttle position sensors. The ECM controls the throttle valve by applying a varying voltage to the control circuits of the Throttle Actuator Control (TAC) motor. The ECM monitors the duty cycle that is required to actuate the throttle valve. The ECM monitors the TP sensor signal/serial data circuit to determine the actual throttle valve position. The TP sensor information is transmitted between the throttle body and the ECM on the signal/serial data circuit. The Diagnostic Trouble Code (DTC) will be set when the ECM determines that the throttle blade did not return to the rest position within 1 s.
