Detailed Product Overview

The Walker Products 200-1357 throttle position sensor reports throttle plate movement to the engine control system so fuel delivery and ignition timing can respond correctly. Accurate throttle signal input is important on vehicles such as the Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac Escalade, where drivability depends on consistent sensor output. This part cross-references Dorman OE Solutions 977-000 for the same application.

Compatible With 2003-2007 Chevrolet Silverado 1500, 2003-2006 Chevrolet Tahoe, 2003-2006 GMC Yukon, and other listed GM applications, Walker Products 200-1357 supports service replacement where the original throttle position sensor has worn, drifted, or failed. The part number 200-1357 is also referenced across multiple aftermarket listings for the same vehicle coverage.

What This Sensor Helps Address

• Erratic or delayed throttle response
• Check engine light related to throttle position signal faults
• Rough idle or hesitation during acceleration
• Incorrect throttle angle feedback to the engine control module
• Driveability issues on GM trucks, SUVs, and vans with throttle body mounted sensors

Installation Notes and Tips

Verify connector style, terminal count, and throttle body mounting before installation. The sensor is adjustable, so final positioning should be set according to the vehicle service procedure after installation. Confirm fitment for the exact year, make, and model, including applications such as Chevrolet Express 2500, GMC Savana 3500, and Hummer H2. The part number 200-1357 should be matched to the original sensor configuration before replacement.
