(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.
