Installation must be performed by a professional. After fitting, a throttle body relearn procedure is required to recalibrate the throttle body position sensor baseline — this is standard throttle body service practice for GM LY7 / Vortec V6 and V8 platforms. Use GM MDI / Tech2 or compatible scanner to perform “Throttle Body Relearn” or “Idle Learn” if issues persist. Non-professionals should not attempt installation, as improper fitting may result in throttle body malfunction. The instruction manual included in the package is for professional reference only.

Common throttle body symptoms on GM LY7 / Vortec V6 and V8 engines include rough idle, hesitation on acceleration, unstable RPM at startup, and fault codes P0638 / P2119 / P2135 / P1516. If basic throttle body cleaning with throttle body cleaner spray has not resolved the issue, a full throttle body replacement is typically the next step.
This throttle body assembly includes an integrated throttle body position sensor – no separate sensor purchase required. A replacement throttle body gasket (GM 12593360 or equivalent) is recommended and sold separately.
Compared to dealer throttle body repair cost, this direct OEM-quality unit offers significant savings while maintaining factory performance standards. Fits Chevrolet Silverado, Tahoe, Suburban, Malibu, Express, Avalanche, Trailblazer; GMC Sierra, Yukon, Savana, Envoy; Cadillac Escalade; Buick Rainier; Pontiac G6/G8; Saturn Aura; Hummer H3; Isuzu Ascender; and Saab 9-7X.
Note: Throttle body adaptation via GM MDI / Tech2 is required after installation. The throttle body gasket is sold separately.
