Campaign - Air Injection Reactor Pump Replacement: Overview

Product Emission - Air Injection Reactor
(A.I.R.) Pump System Failures # 99083

99083 -- Air Injection Reactor (A.I.R.) Pump System Failures

1995, 1996, 1997 Chevrolet Camaro and Pontiac Firebird Model Vehicles

Equipped with 5.7L Engine (RPO LT1-VIN Code P)

Condition

General Motors has decided to conduct a Voluntary Emission Campaign involving all 1995, 1996 and 1997 Chevrolet Camaro and Pontiac Firebird model vehicles equipped with 5.7L (RPO LT1-VIN Code P) engines. The Air Injection Reactor (A.I.R.) pump emission control system on these vehicles may fail to operate and cause the Malfunction Indicator Lamp (MIL) to illuminate. This condition may be due to corrosion of a solenoid internal to the A.I.R. pump.

Correction

Dealers are to install a new A.I.R. pump assembly kit that is designed to protect the A.I.R. pump system from failing due to internal corrosion.

Vehicles Involved





Involved are all 1995, 1996 and 1997 Chevrolet Camaro and Pontiac Firebird model vehicles equipped with 5.7L (RPO LT1-VIN Code P) engines and built within the breakpoints shown.

Important
Dealers should confirm vehicle eligibility through GMVIS (GM Vehicle Inquiry System) or GM Access Screen (Canada Only) or DCS Screen 445 (IPC only) prior to beginning campaign repairs. [Not all vehicles within the above breakpoints may be involved].

Involved vehicles have been identified by Vehicle Identification Number. Computer listings containing the complete Vehicle Identification Number, customer name and address data have been prepared, and are being furnished to involved dealers with the campaign bulletin. The customer name and address data furnished will enable dealers to follow-up with customers involved in this campaign. Any dealer not receiving a computer listing with the campaign bulletin has no involved vehicles currently assigned.

These dealer listings may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any other purpose is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign.

Parts Information





Parts required to complete this campaign are to be obtained from General Motors Service Parts Operations (GMSPO). Please refer to your "involved vehicles listing" prior to ordering requirements. Normal orders should be placed on a DRO = Daily Replenishment Order. An emergency requirement should be ordered on a CSO - Customer Special Order.

Important
Owner letters will be mailed in phases by model year in order to reduce initial pump kit demand. 1996 owner letters will be mailed one week after publication of the bulletin. 1997 and 1995 owner letters will be mailed as part kits become available. Please order accordingly.
