What happens when the throttle pedal moves on a GMC?
When the throttle pedal moves, the throttle sensor also moves in direct response to the driver commands. As the throttle moves, a voltage signal ranging from 0.5 volts to 5.0 volts is sent to the engine computer.
How to replace the throttle position sensor system in GMC?
Replacing the sensor is essential for good performance. Turn off the engine and raise the hood of the GMC vehicle. In most cases, remove the air cleaner that covers the throttle body. Locate the accelerator linkage. Just opposite the throttle lever, on the opposite side of the throttle body, the throttle position sensor is located.
How does a GM throttle body relearn procedure?
A motor and gear reduction set inside the throttle body opens and closes the throttle plate to accomplish your request. Over time, carbon buildup can accumulate around the throttle plate, changing it’s “home” position. If the buildup occurs gradually, the PCM “learns” the new home position.
Can a bad throttle position sensor cause stalling?
Similarly, if your engine struggles to idle efficiently, it could also be a result of a damaged throttle position sensor. Stalling, surging, or hesitating while idling all can be caused by this unassuming sensor. The best way to determine if these issues are caused by your throttle position sensor is to go to the source.

Is the accelerator pedal connected to the throttle plate?
The Accelerator Pedal Assembly is not connected to the throttle plate via a cable (like in the good ole’ days). That the Accelerator Pedal Assembly is made up of 3 individual Position Sensors. Each one has separate signal, Ground, and 5.0 volt reference circuits.
