Emissions Maintenance Light: Service and Repair

Oxygen Sensor Maintenance Reminder Lamp:

On early production models (prior to February 1985), the oxygen sensor should be replaced every 30,000 miles. To alert the operator of the required service, an Oxygen Sensor lamp on the instrument panel is illuminated after the first 30,000 miles of vehicle operation. As the mileage sensor cannot be reset on these models, the indicator bulb must be removed as follows:

1. Remove screw from right side of display unit cover and slide cover off to the right.

2. Remove lamp bulb from behind Oxygen Sensor lens by bending holder.

3. Install display unit cover and retaining screw.
