Code P1516 2015 Chevrolet Silverado Description

The P1516 code on a 2015 Chevrolet Silverado indicates a problem with the Throttle Actuator Control Module (TACM) related to the throttle actuator position performance. The TACM is responsible for controlling the throttle plate position in response to driver input. When this code is triggered, it means that the TACM is detecting a discrepancy between the actual position of the throttle and the position that it is commanding. This can lead to issues with engine performance, fuel efficiency, and overall drivability of the vehicle.
