Part #12588923. Looking to find out where this part is located so I can replace it. It makes my truck go into Engine Reduced Mode. I changed out the sensor on the throttle body and it is still doing the same thing. So, I read codes and says I need to replace the actuator.

Hi,

That is the throttle actuator control module (TAC) module. I attached a pic below of the component to help you locate it.

Additionally, the remaining pics are the directions for the removal and replacement of the module.

Let me know if this helps or if you have questions.

Take care,

Joe
