P1516: Throttle Actuator Control Module – Throttle Actuator Position Performance
The P1516 fault code refers to the Throttle Actuator Control Module Throttle Actuator Position Performance. This code is triggered when the Engine Control Module (ECM) detects an unstable throttle position for more than 1 second. The ECM determines the driver’s intent based on input from the accelerator pedal position sensors and calculates the appropriate throttle response.
It controls the throttle valve by applying varying voltage to the control circuits of the Throttle Actuator Control (TAC) motor. To determine the actual throttle valve position, the ECM monitors the TP sensor signalserial data circuit.
This information is transmitted between the throttle body and the ECM. If the ECM detects an unstable throttle position, it will set the P1516 fault code.
It is important to address this issue promptly as an unstable throttle position can affect the performance and efficiency of the vehicle. A qualified technician should diagnose and repair the underlying cause of the fault code to ensure proper throttle control and optimal engine performance.
