2018 GMC Sierra 1500 Accelerator Pedal

The pedal sensor reports the driver's input, while a throttle position sensor reports the throttle's position. They provide different information to the engine controls and are not interchangeable replacement parts.

Some A-Premium assemblies explicitly include the position sensor, while other listings sell a sensor separately. Read the selected package and match it to the part that can be serviced on the vehicle.

Terminal count is only one part of the electrical match. Connector shape, signal arrangement, mounting and vehicle application also matter. Use the sensor specified for the existing pedal system.

Setup requirements vary by system. Some controls learn pedal limits automatically, while other vehicles may require a particular verification or diagnostic procedure. Follow the service information for the vehicle instead of assuming one sequence works for every pedal.

Some electronic throttle systems enter a limited operating mode when pedal signals are inconsistent. The warning can also have other causes, so read the fault information and test the relevant circuits before replacing the sensor.
