Notice of "check Gas cap" came up dashboard Tuesday. Gas cap was tight. Repair shop Cleared code - light went out. On Wednesday check Eng light came on. Replaced Gas cap. Repair shop Cleared code again- light went out. On the way home light came back on again. Diagnostic meter says "Emission Sensor Valve" Both times -->i believe was the Code name when they told me to tighten and/or change the Gas Cap which neither worked. Any suggestions?? What & where is the Emission Sensor Valve??
