INTRODUCTION
This bulletin describes procedures for the inspection and replacement of the exhaust gas sensor on 1981 Non-Turbo 280ZX (S130) and 810 Gasoline Maxima (910) Federal model Datsuns.
BACKGROUND
Nissan has determined that the current criteria for replacement of the exhaust gas sensor should be changed to assure proper emission control. The current inspection procedure for checking the exhaust gas sensor calls for replacing the sensor if the inspection lamp on the EFI control unit goes on and off five times or less during 10 seconds. Nissan has revised the inspection procedure to require that the sensor be replaced if the inspection lamp goes on and off ten times or less during 10 seconds. This revised procedure applies only to 1981 Federal model Non-Turbo 280ZX (S130) and Gasoline 810 Maxima (910) vehicles and is to be used both for this campaign and anytime the exhaust gas sensor is inspected.
Nissan will notify all owners of the affected vehicles by letter. They will be asked to bring their vehicle to a Nissan/Datsun dealer for free inspection and, if necessary, replacement of the exhaust gas sensor. A copy of the owner's letter is shown on page 14/14 for your information.
Nissan has undertaken this voluntary service campaign to assure that air pollution is not aggravated by its vehicles.
AFFECTED MODELS
All 1981 Non-Turbo 280ZX (S130) and Gasoline 810 Maxima (910) Federal model vehicles are included in this service campaign (California vehicles are not included).
