STOP OXYGEN SENSOR REPLACEMENT -MAINTENANCE SCHEDULE UPDATE-

The 1982 Maintenance Schedule for gasoline fueled passenger cars incorrectly specified that all 1982 Chevettes equipped with Computer Command Control and automatic transmission require oxygen sensor replacement at 30,000 mile intervals. This is true only for Federal 1982 Chevettes equipped with Computer Command Control and automatic transmission. There are no 1982 California vehicles that require scheduled oxygen sensor maintenance.

The Federal 1982 Chevettes equipped with Computer Command Control and automatic transmission have an odometer maintenance flag which signals the operator that a sensor change is to be performed when the vehicle has accumulated 30,000 miles. The cost of this maintenance is to be assumed by the owner.

The engine family designation on the "tune-up label" may be used to determine the need for a sensor change:

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those 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 equipment, tools, 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 a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
