- Q:What are the details about the oxygen sensor replacement procedure and emissions maintenance timer? Posted by Customer
- A:Pre-1991 models have an emission maintenance timer under the dashboard that triggers the indicator light for oxygen sensor replacement (around 82,500 miles). The timer can't be reset and must be replaced or disconnected to turn off the light. 3: The timer is located under the instrument panel, right of the steering column. Unplug the connector, remove screws, and lower the timer. Installation is the reverse. 4: Post-1991 models require a special tool to reset the indicator light after oxygen sensor replacement. Visit a dealer or equipped repair facility for light reset.Posted by MoparPartsGiant Specialist
