[problem] Comes on every 30,000 miles. [solution] Check and replace (if needed) the oxygen sensor. Then reset the sensor light. Drop the glovebox door by pressing in the sides releasing the door stops from their holes. Remove the screws (4 trim/2 latch). Pull the box out and lower it out of the way. At the top of the glovebox frame slightly to the left locate a relay. On the right side of the relay you'll feel a rubber-covered button/plunger. Press it in and you'll hear the relay spring reset. Turn the ignition switch on, the sensor light should be off. Reassemble. After 90,000 miles you disconnect the light. Remove the panel just below the steering wheel (at the drivers' knees). On the left you will see a group of wires taped together going into a wiring harness. Taped to this group of wires will be another wire (green/yellow I think) with a plug (white plug) - this is the wire for the sensor light - unplug it. This description (or something close to it) can be found in the Haynes manual - look under Oxygen Sensor in the index. [name]
