"Check Engine" light and "VSS" lights came on the yesterday during normal driving. 20 miles later, had the code pulled at AutoZone. 2004 Sequoia, 65k. Recent brakes. Gassed up about 200 miles ago, checked the gas cap anyway, no difference. Someone suggested the charcoal cannister is flooded; Very strange since I always stop pumping gas at the 1st 'click' just to avoid flooding the charcoal cannister.
