P1516 CHEVROLET - Throttle Actuator Control Module Throttle Actuator Position Performance...Possible causes; Faulty Throttle Actuator Control (TAC) module, Throttle Actuator Control (TAC) module harness is open or shorted, Throttle Actuator Control (TAC) module circuit poor electrical connection, Check Throttle Actuator Control (TAC) module connector for water, Binding or bent throttle plate-failed throttle body.....Here is a video on the fix for this... https://youtu.be/U2DjMcM_Quk
