GM Bulletin No.: 13254 Date: August 2014 Service Bulletin SERVICE UPDATE SUBJECT: Service Update for Inventory and Customer Vehicles Rough Engine Operation, DTC P16A1, MIL, Reduced Power Mode Expires with Base Warranty MODELS: 2014 Chevrolet Silverado 2014 GMC Sierra Equipped with 5.3L V8 Engine (L83) This service update includes vehicles in dealer inventory and customer vehicles that return to the dealership for any reason. This bulletin will expire at the end of the involved vehicle's New Vehicle Limited Warranty period. PURPOSE This bulletin provides a service procedure to install a new throttle body assembly and perform the throttle body learn procedure on certain 2014 model year Chevrolet Silverado and GMC Sierra vehicles equipped with a 5.3L V8 engine (L83). The throttle position sensor may cause the engine to run rough, set a P16A1 DTC, illuminate the malfunction indicator lamp and/or an Engine Reduced Power message. If this occurs, it could result in reduced engine power. This service procedure should be completed as soon as possible on involved vehicles currently in dealer inventory and customer vehicles that return to the dealer for any type of service during the New Vehicle Limited Warranty coverage period. VEHICLES INVOLVED All involved vehicles are identified by VIN in the Global Warranty Management System – Investigate Vehicle History Application. Dealership technicians should always check this site to confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is important to routinely use this tool to verify eligibility because not all similar vehicles may be involved regardless of description or option content. Additionally, a list of involved vehicles currently in dealer inventory is available on the “Service Update Bulletin Information” link under the “Service” tab in GM GlobalConnect (US) or attached to the GlobalConnect message (Canada) used to release this bulletin. Customer vehicles that return for service, for any reason, and are still covered under the vehicle's base warranty should also be checked for vehicle eligibility. Copyright 2013 General Motors.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the tools, equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your dealer for information on whether your vehicle may benefit from the information. We Support Voluntary Technician Certification
