Throttle Body & TPS

Shop New OEM throttle bodies and throttle position sensors (TPS) for GM vehicles. Our factory-original electronic throttle control (ETC) assemblies are sourced from GM surplus — the correct bore diameter, default blade position, and sensor calibration for your engine's drive-by-wire system.

The electronic throttle body is a precision assembly — the TPS provides two independent position signals that the ECM monitors for blade position and sensor rationality. An OEM throttle body provides the exact sensor output curves and blade return spring force that your engine management system was calibrated to expect.

Throttle body replacement may require ECM throttle body adaptation reset using a scan tool. Verify part numbers against your engine RPO code before ordering.
