SPECIAL COVERAGE ADJUSTMENT
This special coverage covers the condition described above for a period of 10 years or 120,000
miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed in service,
regardless of ownership.
Dealers are to replace the throttle body assembly and gasket for Bosch equipped vehicles, or to
install the throttle position sensor kit for Hitachi equipped vehicles. The Hitachi throttle body
assembly only needs to be replaced if the sensor kit does not correct the condition. The repairs will
be made at no charge to the customer. For vehicles covered by Vehicle Service Contracts, all
eligible claims with repair orders on or after September 24, 2015, are covered by this special
coverage and must be submitted using the labor operation codes provided with this bulletin. Claims
Copyright 2015 General Motors. All Rights Reserved.

with repair orders prior to September 24, 2015, must be submitted to the Service Contract provider.
VEHICLES INVOLVED
All involved vehicles are identified by Vehicle Identification Number on the Applicable Warranties
section in GM Global Warranty Management system. Dealership service personnel 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.
PART INFORMATION
Parts required to complete this recall are to be obtained from General Motors Customer Care and
Aftersales (GMCCA). Please refer to your “involved vehicles listing” before ordering parts. Normal
orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts
should be ordered on a CSO = Customer Special Order.
Note: Due to limited initial parts availability, dealers are encouraged not to order recall parts for use
as shelf stock. Parts should only be ordered when inspection determines that it is necessary to
replace the throttle body and/or gasket(s). Parts may have quantity limiters in effect.
Note: Use the vehicle identification number (VIN), SI, and the GM Electronic Parts Catalog to
determine which part to order.

Note: The gasket between the throttle body and the intake manifold may need to be replaced
when performing the following procedures. The gasket is included with some replacement throttle
body assemblies, if the gasket is not included with the service assembly, order the part. Use the
vehicle identification number (VIN), SI, and the GM Electronic Parts Catalog to determine which
gasket to order.
SERVICE PROCEDURE
Note: There are two repair procedures in this bulletin. Follow the correct procedure based on the
service part supplier. The part table above identifies the service part as a Bosch or Hitachi
supplied component.
With a scan tool, verify that DTC P2135, P0121 OR P0221 is set as Current or in History.
 If DTC P2135, P0121 OR P0221 is NOT set as Current or in History, no further action is required.
Inform the customer that any additional diagnosis and repairs are not covered under this special
coverage.
 If DTC P2135, P0121 OR P0221 is set as Current or in History, refer to the service procedures
below. Bosch supplied throttle bodies require that the throttle body be serviced by replacing the
complete assembly. Hitachi supplied throttle bodies only need the Throttle Position Sensor Kit
installed to correct the condition. Only replace the Hitachi throttle body assembly if the sensor kit
does not correct the condition.
REPAIR PROCEDURE FOR BOSCH EQUIPPED VEHICLES
Replace the throttle body assembly and gasket. Refer to Throttle Body Assembly Replacement in
SI.
REPAIR PROCEDURE FOR HITACHI EQUIPPED VEHICLES
Use the following steps to replace the Throttle Position Sensor Cover.
Note: Handle the electronic throttle control components carefully. Use cleanliness in order to
prevent damage. Do not drop the electronic throttle control components. Do not roughly handle
the electronic throttle control components. Do not immerse the electronic throttle control
components in cleaning solvents of any type.
Note: If at any time during this procedure the throttle body is dropped, abort this procedure and
REPLACE it with a new throttle body assembly.
1. Remove the throttle body and discard the throttle body gasket. Refer to Throttle Body
Assembly Replacement in SI.
2. Remove any loose debris and dirt from the throttle body assembly and the TP sensor cover.
Inspect the throttle body for damage.
Note: Do not use any solvent that contains Methyl Ethyl Ketone (MEK). This solvent may damage
fuel system components.

CUSTOMER NOTIFICATION
General Motors will notify customers of this special coverage on their vehicles (see copy of typical
customer letter included with this bulletin - actual divisional letter may vary slightly).
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/retailer for information on
whether your vehicle may benefit from the information.
