General Motors Throttle Position Sensor Restore accurate throttle control and engine response with this throttle position sensor designed for General Motors vehicles. This sensor measures throttle valve position and communicates that information to the engine control module so fuel delivery, ignition timing, and idle control respond correctly. Key benefits Improves drivability by restoring correct throttle signaling to the engine control module Reduces or prevents rough idle, hesitation, and stalling caused by a faulty sensor Helps clear throttlerelated diagnostic trouble codes and reduces the chance of an illuminated check engine light Straightforward replacement that helps the vehicle to factorylike performance What it does (functionality) Detects the position/angle of the throttle plate and converts it into an electrical signal for the vehicle's engine control system Provides consistent feedback to support proper fuel and ignition management across idle, cruise, and acceleration ranges Compatibility and fit Intended for use with General Motors vehicles; designed to integrate with the vehicle's throttle control and engine management systems Vehiclespecific fitment may vary by model year and engine configuration; verify compatibility with your vehicle before Key attributes Construction: built for automotive use with materials and sealing suitable for enginebay conditions Size and form factor: compact sensor designed to mount at the throttle body for a direct, stable connection Performance: engineered to provide repeatable, accurate throttle position feedback for reliable engine control Common applications / use cases Replacement for a failed or erratic throttle position sensor that is causing poor idle, hesitation, or reduced fuel economy Preventive maintenance when diagnosing throttle control or engine management issues during routine service Use during engine tuning or throttle system repairs to ensure the engine control module receives accurate position input Installation and maintenance Typically mounts at the throttle body and connects to the vehicle wiring harness; professional installation recommended if you are not experienced with engine sensors Inspect connector and wiring for corrosion or damage when replacing the sensor Notes Confirm vehicle compatibility by referencing your vehicle's make, model, and year before installation If diagnostic trouble codes persist after replacement, inspect related components such as throttle body, wiring, and the engine control module for faults
