I had this exact same thing happen with my wife's 4runner. At first I was told it was an O2 sensor; but then after driving it for alost 6 months with the light on-- I finally took it back in to be re-troubleshot. The scanner pulled it up as the fuel to air sensor. It was replaced for about $300 +/-. I had to drive it another 500-700 miles before the light reset. Problem solved.
Can't tell much without scanning it. Sometimes a code in the engine computer will disable other systems and cause the other lights to go on. Bring it somewhere and get it scanned. If your a DIY'er bring it into one of the autoparts stores (ie:autozone) and have them scan it for you for free.
