OEM GM Throttle Sensors

The throttle sensor ensures that you get the best fuel efficiency and performance from your vehicle by sending information about the position of the throttle to the ECU, which determines the idle speed of the motor. The throttle is controlled by driver acceleration.

The sensor helps to maintain a proper speed no matter what vehicle you drive. It is designed to be replaced rather than repaired because it is enclosed in a case on the throttle itself. It fits on the butterfly shaft so that it can directly monitor the position.

Regardless of whether you drive an Enclave, a Suburban 1500, or a Corvette, you want to replace the throttle sensor with a genuine OEM GM replacement part in order to get the most performance from the part. OEM parts are built to GM specifications, so they are as reliable as the factory parts.

The throttle sensor may never go bad in your vehicle, but they are very sensitive to heat, vibration or water, so they can fail if they are exposed to any of these things. They may also age to the point of replacement. You will notice it first in poor performance from your engine and will experience symptoms such as hesitation and misfiring.
