Q:
What are the details about the oxygen sensor replacement procedure and emissions maintenance timer? Posted by Customer
A:
On 1990 and earlier models an emission maintenance timer (mounted under the right side of the dashboard) activates the emissions maintenance indicator light on the instrument panel when the oxygen sensor is scheduled for replacement (approximately 82,500 miles). The timer cannot be reset and must be replaced or disconnected to turn out the indicator light. 3: The timer is located under the instrument panel, to the right of the steering column. Unplug the electrical connector, remove the screws and lower the timer from the instrument panel. Installation is the reverse of removal. 4: On 1991 and later models, the emissions maintenance indicator light can only be reset with a special tool available at most auto parts stores. After replacing the oxygen sensor, take the vehicle to a dealer service department or other properly equipped repair facility and have the light reset.
