Federal trucks acts as an emission maintenance warning. The Malfunction Indicator (CHECK) Light will come on at 80,000 miles indicating that
the Oxygen sensor service is required.
To reset the warning light (after servicing the Oxygen sensor). Remove the instrument cluster. See: Instrument Panel, Gauges and Warning
Indicators/Instrument Cluster / Carrier Locate lettered reset holes (NC and NO) on the rear of the instrument cluster. Remove the screw from the
lettered reset hole and reinstall it in the other hole.
