Detailed Description

The Standard Ignition S20050 throttle body is used in the air and fuel delivery system to regulate airflow into the engine based on electronic throttle input. This part is specified for a wide range of GM platforms, including Chevrolet Silverado 1500, GMC Sierra 1500, Chevrolet Express 1500, GMC Savana 1500, Chevrolet Malibu, Pontiac G6, Pontiac G8, and Saturn Aura. The connector and terminal layout are important for proper electrical matching, and this unit uses a female connector with six male blade terminals.

This part cross-references Dorman - OE Solutions 977-313 and Spectra Premium TB1021 for the same application. Standard Ignition S20050 is also listed against OE and aftermarket numbers including 12595829, 12615503, ETB112, ETBB10003, and NTB1020.

Common Replacement Reasons

• Throttle response issues caused by a worn throttle body
• Idle instability or rough idle related to airflow control
• Electronic throttle faults tied to connector or terminal wear
• Reduced drivability from carbon buildup or internal throttle wear
• Check engine light conditions associated with throttle body performance

Installation Notes and Tips

Verify connector gender, terminal count, and blade-style terminal layout before installation. On 2013 GMC Savana 1500 applications, a factory relearn procedure is required after installation. After replacement, follow the vehicle-specific throttle relearn or idle relearn procedure so the engine control module can calibrate throttle operation correctly.

Quality Assurance

Standard Ignition supplies replacement ignition and engine management components for OE-style service applications. The S20050 is built to match the listed GM fitments and electrical configuration for straightforward parts matching during repair.
