Codes P1516 and p2101

Hello,

The codes:
P1516: Throttle Actuator Control (TAC) Module Throttle Actuator Position Performance.
P2101: Throttle Actuator Position Performance.

One of the most common causes for the engine to go into limp mode is having a dirty throttle actuator. When the actuator is dirty it is unable to send correct data to the ECM, and that can trigger the limp mode with no power or acceleration.

First try cleaning out the throttle actuator then clear the codes and see if that takes care of the issue.

Here is a helpful guide on how to clean the throttle actuator:

Let me know of any questions.
Thank you.
